BenQ EW2740L

VA (Vertical Alignment) panels have been somewhat overshadowed recently by far more common alternatives such as TN (Twisted Nematic) and IPS (In-Plane Switching). With vastly superior contrast, though, there is still a bit of a craving for the VA flavour. The BenQ EW2740L is a recent release from a company who pumps out VA monitors like no other. As a new addition to their ‘Eye-Care’ range a key feature is the use of a flicker-free backlight to promote greater visual comfort. Their continued interest in these unique panels should come as no surprise given that they are the parent company of the main VA panel manufacturer, AUO. We put this 27” VA model through its paces in our ruthless gauntlet of ‘real world’ tests to find out what it’s made of.

Specifications

The monitor uses a 27” AU Optronics AMVA panel which is capable of outputting ‘true 8-bit’ colour per subpixel and pumping out a respectable 3000:1 static contrast. As standard for such a monitor there is a ‘Full HD’ resolution and a specified grey to grey response time of 4ms. As no doubt our testing will reveal, this response time figure shouldn’t be taken at face value as a point of reliable comparison with other monitors.

For your reading convenience the key ‘talking points’ of the specification have been highlighted in blue below.

Features and aesthetics

The front of the monitor reveals a few (in our opinion) attractive design features. The bezels are matte black plastic and very thin – 11mm (0.43 inches) at the top and sides and 16mm (0.63 inches) at the bottom. The stand neck is glossy black plastic at the front, running forwards down the centre of the stand. Either side of this the stand is matte black plastic with a brushed metal texture. The screen surface is very light matte (‘semi glossy’). This provides good anti-glare properties without imparting obvious graininess or sapping too much vibrancy from the image.

In the above photo you can make out the outlines of the Windows and some other objects in the room in a way that is clearer than on ‘regular’ matte surfaces but without the distinct reflections of glossy. Once the monitor was switched on and placed in more sensible lighting conditions without strong direct light hitting the screen, the image was not impaired by glare or reflections. The OSD (On Screen Display) is controlled by touch sensitive areas at the front of the screen. The functions are as follows; ‘Custom Key 1’ (Low Blue Light mode by default), ‘Custom Key 2’ (input select by default), ‘Custom key 3’ (volume by default), ‘Menu’ and ‘Exit’. The buttons are reasonably sensitive, more so than touch-sensitive buttons on glossy surfaces tend to be. Aside from the dim green power LED hanging down beneath the power button, there is no illumination here. This can make operation tricky in the dark, unless you are quite used to the button layout. Functions are labelled on-screen, at least.

The main menu uses BenQ’s ‘Intuitive UI’ style and is fairly straightforward with a good selection of features. Once in the main menu the buttons are used for navigation; ‘Up’, ‘Down’, ‘Right’, ‘Left’ and ‘Exit’. Most features are self-explanatory or are covered in various parts of the review. The main new feature is the selection of ‘Low Blue Light’ modes. Some relatively new features include ‘Super Resolution’ which really just increases sharpness. This makes things look overly sharp and is designed for low resolution content primarily. ‘Smart Focus’ also features as demonstrated briefly in the video below, alongside a run-through of the rest of the OSD.

At the side the monitor is fairly thin and features glossy black plastic (aside from where the front bezel attaches). It is 18mm (0.71 inches) at thinnest point but bulks out centrally to around 50mm (1.97 inches).

The rear of the monitor is dominated by glossy black plastic, making it difficult to photograph in decent light without a lot of reflected clutter. There is no VESA mounting on this model and a rather unique vertical port arrangement. There are two speaker grills either side of the ports housing stereo speakers. The sound quality is quite reasonable for integrated monitor speakers. The sound was not particularly dynamic and had fairly weak base. At the same time it didn’t sound overly tinny or distorted and had fairly crisp treble in places. The sound maintained these qualities even at maximum volume, which is reasonably loud given the small speaker size.

The ports, from top to bottom are; VGA, 2 HDMI ports, 3.5mm line-in, 3.5mm headphone jack and DC power input to attach the included power brick to. The lower HDMI port features MHL (Mobile High-definition Link) which will allow the monitor to display the contents of and output audio from a compatible smartphone and also charge it. Samsung Galaxy phones require an additional adaptor to use MHL, although charging is supported. A VGA cable and HDMI cable is included in the box.

Calibration

Correcting the HDMI colour signal

Our test system used an Nvidia GTX 780 connected via HDMI. By default Nvidia GPUs send out a limited range colour signal over HDMI designed for HDTVs and monitors configured in a specific way. The image looks somewhat flooded and it is clearly missing the black depth and contrast you’d expect from a decent VA panel. If you go onto the OSD main menu and go to ‘Picture Advanced’. ‘HDMI RGB PC Range’ then cycle to ‘RGB(0~255)’ and back to ‘RGB(16~235)’ it vastly improves things. You have to do this every time you switch preset, which is rather inconvenient unless you settle on some specific settings and leave it at that. Things do look, at least on the surface, very nice with the monitor set to ‘RGB(16~235)’ on Nvidia graphics cards.

If you want to unlock slightly more contrast and not have to worry about toggling this ‘RGB’ setting every time you switch presets you can instead ensure the GPU is sending a Full Range RGB signal designed to bring out the full potential of the monitor. The easiest way to do this is to download this utility. You just run the.exe file included in the.zip and click the button at the top right which is labelled ‘Set Full Range (0-255)’, as shown below.

This utility modifies the graphics driver registry entries controlling the HDMI colour signal to ensure the correct Full Range RGB signal is sent out to the monitor. You must restart your computer for the changes to take effect. You should then go back to ‘Picture Advanced’. ‘HDMI RGB PC Range’ in the OSD and cycle to ‘RGB(0~255)’ to ensure the monitor picks up and uses the Full Range RGB signal. If you install a new graphics driver you should re-run the utility, although with the modern Nvidia upgrade process integrated into the driver that isn’t always necessary. AMD GPU users should find that the ‘HDMI RGB PC Range’ option is greyed out and the image looks nice out of the box. If you are an AMD GPU user and like to fiddle about with graphics driver settings you may be able to improve the contrast or general image just slightly. See the ‘Calibration’ section of our BenQ GW2760HS review for details on how to do this.

Testing the presets

The BenQ EW2740L has a broad range of ‘Picture Mode’ Senseye 3 presets available; ‘Standard’, 4 ‘Low Blue Light’ presets (‘Multimedia’, ‘Web Surfing’, ‘Office’ and ‘Reading’), ‘Cinema’, ‘Game’, ‘Photo’, ‘sRGB’, ‘Eco’, ‘M-book’ and ‘User’. Rather than going through each preset and in many cases saying why we don’t like the image in said preset and don’t recommend using them we will instead FOCUS on those we do find appealing. In addition we will be taking a look at the effect on the image of applying the 5 different ‘Gamma’ settings available in the OSD. The table below gives the white point, average gamma, preset-specific OSD features available and general observations about the image using a range of settings. The readings and observations in this table were based on testing using a Spyder4Elite colorimeter alongside some familiar games, desktop images and other applications. We corrected the HDMI colour signal to Full Range RGB as detailed above but used default settings elsewhere, unless otherwise specified.

The EW2740L provided a decent image straight from the box. It was fairly satisfying visually with (correctable) brightness, gamma and white point issues which caused the image to appear cool and some shades to appear deeper than they should. This blue tint to the ‘Standard’ preset was a bit strange given that when the colour channels were completely unaltered in the ‘User’ preset there was a warm and green tint instead. We suspect this may be to try to accentuate the differences between this and the range of ‘Low Blue Light’ settings available on the monitor. These settings provide lower brightness and a warmer, softer look to the image. This can be achieved manually by altering brightness, sharpness and the colour channels. HEVL (High Energy Visible Light), such as blue light from monitor backlights isn’t something you generally have to worry about from an eye health perspective, but for comfort and other reasons it can be important. Eye health aside, we don’t want to take too much away from the ‘Low Blue Light’ modes, as we feel it is nice to have a range of easily accessible presets for this sort of thing. We personally like to make use of such settings in the evening, for example, where blue light can interfere with sleep and make you feel more awake than you’d like.

For our test settings, covered in the following section, we used the ‘User’ mode and manually adjusted the colour channels. We also used ‘Gamma 2’ rather than the default of ‘Gamma 3’ as this gave the closest fit to the 2.2 curve that many users find desirable.

Test Settings

We adopted the following for our test settings. It should be noted that individual units can and likely will vary, in particular when it comes to colour temperature. You should therefore feel free to make your own adjustments instead. The default ‘Gamma’ setting also provides a slightly deeper image which isn’t necessarily desirable for accurately represented colours but may be preferred by some users. It’s nice to have this sort of flexibility, of course.

Brightness= 58 (according to preferences and lighting)

Contrast and brightness

Contrast ratios

We used a KM CS-200 luminance meter to accurately measure white and black levels using a range of monitor settings. From these values contrast ratios were calculated, which are shown in the table below alongside the other readings. The highest white luminance, lowest black luminance and highest static contrast ratio recorded has been highlighted in black. The readings and contrast ratio for our test settings are highlighted in blue.

The static contrast readings on the EW2740L were strong. You could see the result of this on the desktop. Black text was deep and inky and images had a really defined look with excellent distinction between dark and light shades. On standard mode the average contrast ratio recorded was 3269:1, excluding ‘0% brightness’ where the black luminance was too low to be accurately recorded by our luminance meter. This is quite close to the 3000:1 specified for the panel. ‘Standard’ mode makes significant adjustments to the colour channels, not necessarily ideal ones at that. When the colour channels were left completely alone (‘User: Color Temperature= User Define’) a very impressive contrast ratio of 5114:1 was recorded, far exceeding the panel specifications. Following the changes made for our ‘Test Settings’ a contrast ratio of 3660:1 was recorded which is still very pleasing. good news came from the various ‘Low Blue Light’ settings which actually used colour channels closer to the native warm tone of the panel and yielded contrast ratios of 4000:1-4625:1. The luminance range of the monitor was also exceptional, ranging from an extremely low 11 cd/m2 to a maximum of 358 cd/m2 based on the readings we took. This gives a 347 cd/m2 luminance adjustment range – and a lot of flexibility, allowing a comfortable brightness to be achieved for pretty much any user.

There is a ‘Dynamic Contrast’ setting that can be activated in the ‘Game’, ‘Cinema’ and ‘Photo’ presets. You can choose how broad the brightness range is (from 1-5) for this setting. Even at the lowest setting the monitor tended to produce rather high brightness at its dimmest. Using a higher setting simply produces brightness that ranges from high to very high. The backlight didn’t seem to dim appropriately when very dark images were displayed – even an entire black screen. Considering that this mode can only be activated in some of the poorer image presets and that the static contrast is very high on this model it seems a waste of the monitors capability to use it. So we won’t get hung up over this poor Dynamic Contrast implementation.

PWM (Pulse Width Modulation)

As the marketing for this model suggests, being part of BenQ’s ‘Eye-care’ initiative, it’s designed to promote the best possible visual comfort for the user. One aspect of this is the ‘Low Blue Light’ modes which we explored previously. The other is the claim of a ‘flicker free’ backlight, which we can confirm from our testing is correct. This model does not use PWM (Pulse Width Modulation) to modulate backlight brightness. Instead it uses a DC (Direct Current) method to control backlight brightness at any brightness setting – even ‘0’ where 11 cd/m2 was recorded. Some users are sensitive to or suffer visual discomfort from the flickering that is associated with the use of PWM, so it’s nice to see BenQ continue their drive to banish PWM-regulation for their monitor backlights.

Luminance uniformity

Observing a black screen in a dark room using our test settings revealed no noticeable backlight bleed. There was a small amount of clouding, particularly at the bottom two corners. This was very faint even in a dark room (shown in the picture below) and was not noticeable during normal use. There was also a mild silver-purple glow, something we dub ‘VA glow’, visible from de-centralised viewing angles. This was visible to some degree from a ‘normal’ viewing position, in a dark room, at the very edges of the screen but was very faint and nothing like ‘IPS’ or ‘PLS’ glow in its intensity. The video in the ‘Viewing angles’ section shows how this manifests itself from varied viewing angles.

A Spyder4Elite was used to assess the luminance uniformity of ‘pure white’ at various points of the screen. This is a good indicator for potential brightness deviations when displaying various lighter colours and not just white. 9 ‘quadrants’ were analysed running from top left to bottom right. The table below gives these readings as well as the percentage deviation between each quadrant and the brightest recorded point on the screen.

Luminance uniformity table

The luminance uniformity of the monitor was good. The brightest point was ‘quadrant 5’ at the centre of the screen (189.8 cd/m2). The greatest deviation from this, 11%, occurred at ‘quadrant 3’ at the top right of the screen (168.3 cd/m2). There was a 10% deviation at ‘quadrant 2’, the top central region, with single-digit deviation elsewhere. This is a pleasing result from our unit. The graphic below gives a visual representation of these deviations as a contour map with percentage deviation between each quadrant and the brightest point. Darker greys here represent greater deviations than lighter greys.

Luminance uniformity map

It is important for some users not just to consider deviation in brightness at various points of the screen, but also colour temperature. Using the same 9 quadrants the Spyder4Elite also assessed deviation in white point (colour temperature). The graph below shows deviations in DeltaE between each quadrant and the quadrant that’s closest to the 6500K (D65) target white point. Darker colours on this graph again signify greater deviations than lighter colours. Anything above a DeltaE of 3 is generally considered to be significant deviation that some users will see quite readily by eye.

Colour temperature uniformity map

The central point (‘quadrant 5’) is closest to the 6500K target. With a maximum deviation of 1.4 DeltaE (‘quadrant 3’ and ‘quadrant 6’ at the top right and centre right, respectively) the deviations from in colour temperature compared to this central point are minor. As with all uniformity issues, including backlight bleed and variations in luminance and white point, it’s important to remember that individual units of the same model can vary. Our unit performed consistently well here which is always good to see. It’s also important to remember that none of these tests take into account variations due to viewing angle, such as ‘gamma shift’, which is explored subjectively later on. This doesn’t affect the appearance of white or black but can affect shades between this.

Contrast in games and movies

The contrast performance was excellent overall on Battlefield 4. Dark and shaded areas showed very good levels of detail. There was a degree of so-called ‘black crush’ where some of the darkest non-black shades would blend into the black somewhat with visibility improving if you look at the screen from an angle. This is due to the gamma shift behaviour typical for a VA panel and actually seemed less pronounced than on many AMVA panels. The EW2740L performed similarly to the GW2760HS in this regard which features something dubbed ‘Color-shift Free’. Such marketing wasn’t used on this model, but the capabilities seem intrinsic to its new ‘AMVA’ panel anyway. It isn’t only the level of detail that’s important but how this is achieved. IPS and TN panels can use gamma modifications to selectively enhance low-end visibility at the expense of a somewhat ‘flooded’ look to the image. On this monitor dark shades were deep and bold and it didn’t have this flooded look. This is not only desirable in dark areas but also mixed scenes where shadow detail was particularly bold. If you consider vegetation, for example, there was a definite structure that would be lacking somewhat on other panel types. It also helped bring out strong highlights and lighter colours. Bright elements such as neon in-game markets, fires and explosions contrasted beautifully with darker surroundings and really stood out. The screen surface didn’t impart an obvious graininess to such elements, either, so they appeared relatively ‘clean’.

As with Battlefield 4 detail in dark areas on Dirt 3 was very good with even fairly minor detail visible. Some of this was lost due to the aforementioned gamma shifting. However; the overall depth of dark shades and maintenance of detail even near the corners and edges of the screen more than made up for this. The structure and detail levels brought out by these strong distinctions between ‘light’ and ‘dark’ really added something to the game. Vegetation, tire treads, cracks in the road and the materials of buildings highlighted this nicely. Bright elements such as car headlights and interior lights in the dark really ‘popped’ and contrasted very well with their darker surroundings. Such elements didn’t have the absolute smoothness and purity that they would on a glossy screen but weren’t too far off really.

On the Blu-ray movie Skyfall detail levels were excellent in the darkest scenes with even minor detail (such as smooth creases in fabric) visible. Blacks and dark colours in the film also looked very deep and inky at every point of the screen. Bright elements, most notably the neon lights of Shanghai at night, pierced the darkness very well. They had good pop and didn’t appear to be muted too much by the screen surface.

Lagom contrast tests

The Lagom tests for contrast allow specific weaknesses to be identified, even those that may not be readily apparent during other testing. The following observations were made.

Colour reproduction

Colour gamut

The BenQ EW2740L offers quite comprehensive sRGB coverage, particularly good for a modern VA monitor. The image below shows that the monitor’s colour gamut in our test settings follows sRGB closely without any real under-coverage and only slight over-coverage in places. This helps keep the image rich with nicely saturated (but not excessively saturated) colours.

Colour in games and movies

The colour experience on Battlefield 4 was rich, varied and rewarding. The variety of greens (from khaki shades to much deeper and more vibrant shades) was good with pleasing richness throughout the range. The variety and appropriate shade representations helped environments look natural and as they should. Some of the more vibrant colours in the game were quite striking, particularly the red, green and blue ‘neon’ markers. These stood out superbly, especially against darker backgrounds. Reds and oranges from glowing fires and various neon lights on the multiplayer map ‘Operation Dawnbreaker’ also showed good depth and intensity.

The colour performance was also pleasing on Dirt 3. The variety of rich but appropriately saturated colours gave all of the racing environments in the game the look they craved. The distinctions between closely matched ‘dusty’ greens and browns on the Kenyan rally tracks and the variety of lush greens in the Finnish forests were particularly impressive. The monitor also did justice to the vibrant lashings of colour found on the car paint jobs, advertising around the track and game menus. Some stand-out colours here included very rich and deep reds and oranges as well as strong dark blues. Thanks to the semi glossy screen surface colours looked fairly smooth and pure which was nice to see.

On the Skyfall Blu-ray colours had a natural and appropriate look. Skin tones and elements in the environment looked in-place and appropriately saturated. There was good depth and richness to the colours, where it was called for, and a good range of impressively vivid shades. Dark reds and intense blues from some of the lights during the Shanghai night scenes were particularly striking.

The Blu-ray movie Futurama: Into the Wild Green Yonder had the vibrant but varied look that it craves. There were some bold neon yellows, purples and greens with dark star fields in the background that really highlighted how vivid and ‘in your face’ some of the colours could be on this monitor. Even where the contrast was less stark, with bright shades cast around medium shades, the bright shades had plenty of pop. Dark shades had really good depth, too. The variety of subtly different pastel shades was also very good. Although the consistency and therefore ‘distinction’ and ‘identity’ of different shades was not up to IPS levels, the shifts in colour across the screen were less pronounced than on older generation AMVA panels. There were instances where a single solid colour filled much of the screen – the red of Dr Zoidberg, for example. This appeared a marginally lighter red towards the edges of the screen but didn’t have an obvious gradient-like appearance as you’d see on a TN panel. Overall this was an impressive colour performance, giving this title the look it hankers for.

Viewing angles

We took a closer look at colour consistency using Lagom’s tests for viewing angle, where the following observations were made.

• The purple block appeared a lilac colour for the most part with a pink hue towards the far edges and bottom corners in particular. The pink hue didn’t creep in as far towards the centre as usual for a 27” VA monitor.

In the following video we take a look at the viewing angle performance in the Lagom text test, a typical desktop background and a dark desktop background. Here the camera is moved around the desk to show how the monitor may appear when viewed from different viewing angles. The final part of the video shows a slight purple glow in places, the aforementioned ‘VA glow’ that is nowhere near as obvious as IPS or PLS glow.

Responsiveness

Input lag

Using the method described in our review of the AOC g2460Pqu we measured just over 4ms (1/4 of a frame) of input lag on the EW2740L. The signal delay on the monitor is therefore very low and won’t get in the way of the gaming experience.

Pixel responsiveness

We used PixPerAn (Pixel Persistence Analyser), a small piece of software designed to help analyse pixel response performance. Images were captured using a sensitive camera to highlight any trailing (ghosting) resulting from the monitor’s pixel response behaviour. PixPerAn’s speed was set to maximum so that these image represent the worst case scenario for this test. The images below show the results using the three different AMA (Advanced Motion Acceleration) pixel overdrive settings of the monitor; ‘Off’, ‘High’ and ‘Premium’, respectively.

Why care about blue light? Average screen time is over 13 hours per day 1

Screen time and over-exposure to blue light may contribute to digital eye strain. According to the Vision Council, many people experience eye discomfort and vision problems when using digital devices for extended periods. As many as 60% of Americans report experiencing symptoms of digital eye strain 2 which may include:

Review – BenQ GW2785TC Eye-Care monitor

It’s no surprise that we all stare at our screens for most of our waking hours – be it for work, recreation, or just to chat with friends. Honestly, that means our eyes get used the most out of our daily lives, so we should definitely take care of it.

What we have here is something that I’ve tried for the first time – daisy-chaining monitors via DisplayPort MST, or multi-stream transport. Our setup here involves a single USB-C cable to our laptop – and it can charge the laptop while extending to two more monitors!

This is the magic of MST daisy-chaining but that is not the only specialty here. You see, these two monitors are the BenQ GW2785TC monitors and they are within the Eye-Care family of monitors. I’m going to run you through how I use these two monitors for work and what conveniences it offers, while also sharing with you why BenQ’s Eye-Care technology is one of the best in class.

The specs of the BenQ GW2785TC is fairly simple – it’s a:

I’ve also tested the color accuracy of the monitor, so here are the results. It’s pretty good and quite consistent across the two monitors too. Through my own eyes, I can’t even see the color difference between the two monitors. That goes to show that the manufacturing tolerance of BenQ is actually rather good.

The included monitor stand is also very good since the entire installation process is completely toolless, and it has a large, kinda flat base that lets us put stuff on top of the base. It also has height adjustment, tilt, pivot, and rotation.

If you want to use your own monitor arm, then this monitor also supports the standard 100x100mm VESA mount.

Let’s take a look at the ports available on this monitor. So, we have:

We do not have any other ports – especially USB ports, and that is why the cable management of our setup isn’t exactly ideal.

And those two DisplayPorts are where we’ll have to talk about the daisy-chain feature. All we have to do to use the MST feature is to connect the DisplayPort cable from the DisplayPort output on the main monitor and connect it to the second monitor’s DisplayPort input out.

Then, we’ll have to go into the OSD menu of the monitor and enable MST – then Windows will immediately recognize all monitors. This is truly convenient as I can just connect one cable and have two monitors working while charging my laptop too.

However, there are two things that you need to take note of:

• Apple users can stop reading this article because daisy-chaining via DisplayPort MST does not work with Macs
• If you want to connect your keyboard, mouse, or any other USB devices – you’ll have to get another dongle single the BenQ GW2785TC doesn’t have any USB ports – which is what we’ve mentioned earlier.

There are even more features built into the BenQ GW2785TC too – particularly all the features that are under BenQ’s proprietary Eye-Care Technology. We’ll just highlight 3 Eye-Care features that this monitor has.

The Brightness Intelligence Technology (B.I. Tech)

At the bottom of this monitor, we have a little chin. Within this chin is a light sensor that detects your surrounding brightness and change accordingly. I mean, you wouldn’t want to use your monitor at maximum brightness in complete darkness, right?

Low Blue Light Plus Technology

Then, we also have the Low Blue Light Plus Technology. This is to intelligently detect and reduce the amount of blue light that the monitor emits. Don’t worry – the monitor won’t get jaundice as the color only shifts a little bit to a warmer tone.

Flicker-Free technology

One more important technology under the Eye-Care Technology umbrella is the Flicker-Free Technology. This gets a little technical but I’ll try to explain it as simple as possible. Our displays usually work in PWM dimming mode. That means the brightness level that we adjust isn’t actually dimming or brightening up the backlight. It’s actually adjusting how quickly the display flickers in a second to make our brains perceive that level of brightness.

BenQ themselves has a video on this that explains PWM dimming vs DC dimming via animations, which is easier to understand but I think it’s still very technical.

Even though we can’t actually see the screen flickering (some of us can, actually), PWM dimming strains our eyes and potentially causes headaches, and DC dimming is the true “backlight brightness adjustment” as it is consistent stays lit up and never flickers.

ePaper mode Coding mode

One more feature here is the ePaper Mode. If you read a lot of documents, then this is going to be a huge boon for you as the display simulates how a paperback display will look like. Plus, you can rotate the monitor and use it in portrait mode – so it really feels like reading a page out of a newspaper.

And especially for coders, there is a special “coding” profile that you can use that makes codes easier to read. If you’re using editors like Eclipse or Notepad, then the dark mode will look better and cause less eye strain. Combining this “coding” profile with the monitor’s ability to rotate 90º, this makes the BenQ G2785TC a fantastic monitor for programmers around the world.

BenQ Eye-CareU utility

The BenQ Eye-CareU utility can control all of the features that I’ve mentioned in this article too. This utility is very handy since everything is displayed in a handy dashboard. We can even control both monitors via this single software – and expand even further if we have even more monitors daisy-chained to this setup.

But, there is one feature that is not available on the software – and that is the microphone mute button. You see, this monitor has a built-in microphone that we can use.

If you are concerned with privacy, then just hit the button on the monitor to turn off the microphone. We also have an LED here to indicate the microphone status. Nice.

Conclusion

And overall, I think the BenQ GW2785TC is an excellent monitor for those who stare at monitors for long periods of time every day. Remember – we only have one pair of eyes throughout our life, so it’s best to take care of them as much as we can. You can also learn more about the BenQ GW2785TC monitor here.

I mean, RM1,249 is the price that BenQ is asking for this monitor – and I think we can’t put a price to our eye’s comfort.

Why Having a Quality Monitor Like the 4K BenQ EW3270U is Critical To Your Vision

If you stare at a monitor for many hours a day, you can suffer from eye strain or eye fatigue. When shopping for a quality monitor, be sure it has technology to protect your eyes. Review of the BenQ EW3270U monitor. 4K, HDR, 32 diagonal, plus a ton of tech to protect your eyes.

Do your eyes feel tired at the end of the workday after staring at a monitor? Do you get headaches often when you stare at your screen? Does screen flickering make you nauseous? Well, there is a good chance that it is your monitor that is causing these problems. Things like blue light, flicker, refresh rates, having your monitor too bright or too dim, shadows, reflections, ambient lighting, or any combination of these items can actually be affecting your viewing comfort or lack thereof. By not thinking about these combinations, you will suffer from eye fatigue, headaches, lack of energy while working, or having your brain simply too stimulated to relax. So how do you create the proper environment and/or configure your monitor to be optimal for your eyes? Well, you can constantly tweak and fine-tune the settings on your monitor, or you can get one that actually does all of the configurations for you automatically. I will be going into greater details of some of these issues described above as well as reviewing the BenQ EW3270U, a 32” monitor that has all of this built-in! (Disclosure below.)

Ok, got the specs memorized? Great! Let’s learn a bit about eye care!

What You Should Know About Caring for Your Eyes

We have to be a bit grateful for advances in technology. When you think about flat-screen monitors now compared with those huge, bulky, and heavy CRT monitors of a few years ago, you just have to gasp that we managed to survive. And before that? How about just black screens with green text and NO graphics. We have definitely come a long way.

Now we have 4K HDR monitors (like this BenQ one) that can produce billions (with a B) of colors. Our eyes must be a lot happier, right? Not necessarily. Not every monitor is built the same way with the same type of technology. And there are some critical eye care factors that you really need to consider, especially if you are sitting staring at a screen for hours upon hours.

For starters, you should always take a break from staring at the screen. Some people recommend a 20/20/20 rule. Every 20 minutes you should look 20 feet away for about 20 seconds. This will actually let your eye muscles relax a bit. I learned a trick when I was young as well to strengthen the eye muscles. It was something I learned to help with tennis. Hold your finger a foot in front of you, FOCUS on it for a second or two, and then FOCUS on something in the distance for a few seconds. Do this a few times and repeat it regularly. For me, I had to do it to help with a mild case of strabismus when I was a kid. But it is a good exercise to do even today.

And be sure to blink regularly. I have often found myself staring at a screen and my eyes have gotten dried out. Blink and/or use some moisturizing eye drops occasionally.

But let’s talk about a bit of the science and tech behind eye strain and fatigue. There are a few main things you should think about: blue light, flicker, color, and brightness/contrast.

Let’s start with blue light. Visible light that can be detected by humans occurs within the 420 nm and 780 nm spectrum. Beyond 780 nm is infrared light (think about that remote control you have). And at the other end is ultraviolet (below 420 nm). Ultraviolet light (UV) is potentially bad (think sunburns or eye damage if you stare at the sun). But there are visible portions of blue light that the eyes can perceive.

Blue light can be broken up into two types: short wavelength (420-455 nm) and long wavelength (455-480 nm). Interestingly, the short wavelength is bad and the long is good. The short wavelength is closer to ultraviolet and can cause eye strain and blurred vision and even long-term exposure can potentially cause cataracts. The long wavelength, on the other hand, actually can be beneficial during daytime hours as it has been shown to boost attention and positively affect mood control centers in the brain.

So blue light is both good and bad. But luckily the wavelengths differentiating the two have been identified. And that is where technology can come in to play. about how BenQ’s technology in the EW3270U and other monitors in the next section.

The next thing that is truly bad for your eyes is flicker. Monitors over time have gotten better, but as I said, not every monitor is the same. What is flicker in the first place? Basically, it’s the eye detecting changes in brightness during short time periods. Oversimplified, flipping a light switch on and off is a super slowdown example of flicker. Or think about old black and white movies. As the frames rolled by and changed the action on the screen, each film frame would flicker briefly between the next one.

The same thing happens with monitors. The frequency of a shift between on and off (or brightness levels) is defined as the number of times a second this shift happens. So, if you have 5 shifts per seconds, that equates to 5 Hz. The human eye gets bothered up to about 20 Hz (or 20 times per second). At 50 Hz, the eye practically perceives this as a constant light (not registering the on and off).

Flickering also becomes an issue, even more so, when the brightness of the display is lowered. This stuff is a bit above my engineering pay grade (heck, I’m not even an engineer) but it has something to do with Pulse Wave Modulation (PWM) and if it is used for backlighting. These are pulses on and off. But when the brightness is lowered, the “off” setting is longer and it’s during these times that flicker is more obvious. Not all monitors use PWM and you can easily test it by taking a picture of your monitor with your camera. If you see horizontal lines in the output, PWM may be in use. Flicker can also cause eye fatigue, eye strain, and headaches.

There are other backlighting techniques but they aren’t as frequently used due to costs and complicated circuitry. One of these is Direct Current (DC). For long-time viewing, DC seems to be preferred over PWM. BenQ has some “flicker-free” displays which use Direct Current backlighting. The EW3270U is one of those monitors.

Brightness, color, and ambient lighting are also important factors, and they are quite intertwined. When you think about it, if you are near Windows while you work, your workspace is probably subject to lighting changes. If you have your monitor in front of a window, it has bright backlighting at some points doing the day. This can actually be hard on your eyes. And, when it gets darker, having a bright monitor can definitely produce some eyestrain. Couple that with the fact that as you dim a monitor, the color values dim as well, distorting them and creating quite a different picture compared to the original one. So, yes, you can dim the monitor when the lighting around you dims, but you lose color quality in the process. And most monitors you have to dim and adjust manually – who does that? Some BenQ monitors, like this one, will automatically and dynamically adjust based on ambient lighting while still preserving the true color values whenever possible.

So anyway, that’s a LOT to digest, I know. But the key takeaway here is, old monitors are probably bad for your eyes. Newer monitors are better, but they lack many advanced technologies to keep your eyes happy. And some higher-end monitors (like BenQ and others), have the means to dynamically adjust their settings based on your environment while preserving high-definition and key colors.

Let’s take a look at how the BenQ EW3270U handles the challenge.

Review of the BenQ EW3270U Monitor

First, let me start out by saying this is not a scientific review. Nor is it from the perspective of a gamer. I treated this BenQ monitor as simply a work or home-office monitor. I tested using Netflix videos, 4K YouTube videos, photo viewing, web browsing, document editing, and day-to-day tasks. I tried it with different settings on and off (things like HDR set in the system settings).

And, it is important to note, in order to get the best out of the BenQ EW3270U monitor, you really need to be sure that your graphics card can handle it. When I originally received this monitor, I tried to hook it up to my wife’s older computer (which only had VGA and DVI outputs). The EW3270U only allows for HDMI, DisplayPort, or USB Type-C connections. After a quick purchase of a DVI to HDMI cable, I was able to run it in 1080p, but that was the limit to what that type of connection could handle. I wasn’t getting 4K, nor HDR.

So, we made the family decision to get a new, low-end gaming system (which would be the replacement for my wife’s home-office computer – definitely NOT for gaming). It had a good enough video card (an AMD Radeon RX 550) which would be able to support 4K (if you use the proper port). Once we had that computer configured and up and running, the 32” diagonal screen of the EW3270U was magnificent.

Setting up the BenQ EW3270U was extremely easy. You just need a screwdriver. Lay the monitor flat, face down (on some padding), and then slide the monitor stand into place. Then just tighten the screw(s) on the bottom. From there, connect your input devices.

Underneath and behind the monitor are the inputs. This monitor allows you to connect multiple sources assuming you have the proper connections. There are two HDMI inputs, a DisplayPort input, and a USB Type-C input so conceivably, you could have 4 devices attached and just toggle through the inputs. Then just plug the monitor in and head over to configure it. I highly recommend installing the appropriate Windows drivers so that this monitor doesn’t show up as just a “generic PnP monitor.” You can download the drivers here. There is also an audio-out port for headphones or other devices.

One thing became immediately apparent. People have different viewing preferences. And it depends on the type of content you are viewing. If you are a gamer (again, I’m not), be sure that you get an HDR game and you enable the HDR setting in Windows. And, you will probably want to enable FreeSync to prevent screen tearing, stuttering, and jittering during gameplay. I, however, found that I didn’t like having HDR always enabled. It dimmed out the display too much, especially as I was looking at mixed content, some HDR, some not. So, I elected to turn off HDR. If I wanted to get HDR, I could always toggle it back on, or I could use the HDR emulation mode.

Also, as I said, how you have your settings really depends on the content. The BenQ does let you choose (view the buttons under the bezel on the right-hand side) what type of content you are viewing. There are several different types of Picture Modes available:

• Standard – basic PC viewing
• HDR – better color matching
• Cinema HDR – better color for movies
• Low Blue Light (Plus) – decreased blue light
• Rec. 709 – color matching for Standard Rec. 709
• Cinema – good for movies and videos
• Game – gaming mode
• Photo – image viewing mode
• sRGB – color-matching for peripheral devices (printers, cameras, etc.)
• ECO – energy savings
• M-Book – use this if you are connecting a Mac
• User – user-defined settings

You can toggle through each of these settings to find one that you like based on the content you are viewing. And you may want to change it based on the time of day (but there are other settings to automatically help with that).

One of those automatic settings is Bright Intelligence. With this, the monitor uses the built-in light sensor to detect the ambient lighting, image brightness and contrast, and then balance the screen automatically. Remember the previous section where I discussed that? This is one of those nice, automatic things that can reduce eye strain.

Ok, back to the eye strain topic, but specific to this BenQ monitor. There is another menu setting within the monitor called Eye Care. And you will want to spend some time making sure you have this set and use it. Under this menu, you will find the Bright Intelligence setting. But you will also find the Low Blue Light setting. With this monitor and using HDR, you will have different content scenarios: Multimedia, Web Surfing, Office, and Reading. Using these modes will decrease the blue light emitted from the display, thus savings your eyes.

Bright Intelligence Plus (B.I.) is also under the Eye Care menu. You can turn the light meter on or off, as well as adjust the sensitivity of the light sensor here. This may take some testing based on your work environment. You can even have the color temperature change over time as you use the monitor longer to reduce eye strain.

You can adjust the Picture as you see fit (remember, sometimes menu options are not available on the monitor because of the input source or other functions). You can adjust Brightness, Contrast, Sharpness, Gamma, Color Temperature, Hue, Saturation, and AMA from this menu.

Under the Picture Advanced menu, there are some other settings worth talking about. For starters, Super Resolution allows you to increase the pixel density of images that are lower resolution.

Smart Focus magically highlights certain types of content like a YouTube video or a game while dimming out the surrounding area. This is something you need to set manually (it would be really cool if it were able to automatically detect the content and dim out the surroundings).

Controlling and changing all of these settings takes a bit of time to get used to. But once you play around with it for a bit, it becomes much more intuitive. There is one button on the front of the lower-right bezel. On the BenQ EW3270U, this is for HDR and B.I Pushing on this button repeatedly will toggle through the four possible options of on and off for each of the two settings. Your setting will display on the screen.

Underneath the bezel on the right are 6 other control key buttons. From right to left they are: Power, Menu Exit, Menu, Custom Key 2, Custom Key 1, and Low Blue Light hotkey. These buttons also work with the on-screen menu when you are navigating or changing settings. The two on the far left move up and down a menu respectively. The middle one is like pressing “OK.” The menu button either activates the menu or goes back to the previous menu (if a menu is open). And the exit button does just that, exits.

Press these buttons enough and you will get used to it.

Having a large screen is also a definite advantage. At 32” diagonal (actually 31.5”), the view is massive. It’s large enough to be working on an article on one part of the screen while doing research in a web browser on the other. And when it comes to watching movies or viewing and editing images, the details are fantastic.

To test out some of the HDR and 4K capabilities, I watched some HDR/4K movies on YouTube (be sure you select the proper resolution when viewing those videos). I turned on HDR within Windows and the colors were simply amazing. Close-ups of faces actually revealed pores and tiny facial hair (one video that really shows the colors and details is the Real 4K HDR: TCL Four Basic Colors in HDR).

Also, I tested out some HDR content on Netflix (remember, you have to have a compatible Windows computer and use either the Netflix App or the Microsoft Edge browser, as well as have the Ultra HD plan on Netflix). To find HDR content, you can simply search for “HDR” in Netflix.

So, what about pricing of the BenQ EW3270U? Well, since it has so much eye-saving and high-resolution technology built-in, it’s not really a bargain hunter’s dream. The MSRP is 699.00 and you can get it currently on Amazon for 699 as well. (The Amazon page does list other sizes and resolution options but I would highly recommend getting the larger size with the 4K/HDR to truly enjoy movies and images.)
