Laptop connectors: what are they like, how do they look

Choosing a portable computer for work, games or other goals, most people are guided by its technical characteristics. First of all, they are interested in the frequency of the processor, the volume of memory, the capabilities of the video card. At the same time, its equipment is overlooked by other components.

Meanwhile, the number of equipment connected directly depends on which connectors the laptop will be equipped. Let us consider in more detail what connectors have a gadget and why they.

To connect to the Internet

The presence of a special connector for connecting to the World Wide Web now is no longer as relevant as just a few years ago. The development of wireless networks and mass equipment of new Wi-Fi laptop models allows you to reach the Internet anywhere in any place. Nevertheless, in many places ordinary LAN and Ethernet networks are still relevant due to more stable operation and high connection speed.

One of the connectors for connecting the network cable is RJ45. It has almost every model of a portable computer. Outwardly, this port is easily recognizable. a rectangular neckline in the case, eight thin metal contacts and a groove for a latch on a plug. As a rule, the manufacturer provides for one such connector, since the need to connect two wires is extremely rare and when solving specific problems. The main purpose of RJ45: connection to the selected line or connecting a computer with a router, as well as creating a local network by connecting several laptops.

The second type of ports serving for access to the network is RJ11. This connector is identical by which ordinary telephones are connected to the line. It is smaller than RJ45 in size, but also has a characteristic latch. It is used to connect to a worldwide network using a modem, in this case, access is available through a telephone line for a trimmer. This will allow you to remain in touch in those places where a high.speed cable has not yet been extended.

Cable. how to choose the right

If there are different methods of connection, then you need to use the output that gives the best picture quality. HDMI is considered a standard exit. It provides the highest quality signal and it requires minimal settings.

Connect the cable, then turn on the TV and laptop. The connection is carried out immediately after choosing the corresponding channel. If you press it, switching will occur automatically. Now that you were able to connect your laptop to the TV, you can watch your favorite movie or watch your favorite pictures with higher resolution and size.

So, how do you connect your laptop in the most convenient way? Thus, alternative methods may be the best choice. But do you know that you can have two completely different images? This is especially convenient when you want to see something on your big screen, but continue to engage in sewing on your smaller laptop screen.

  • If the devices have the same outputs, then you need to purchase a cable with the same plugs at both ends.
  • In the event that the connectors of the laptop and the TV differ, it is necessary to purchase an adapter or adapter. In the absence of an HDMI connector, you may need to try connecting the HDMI port to the release of the USB laptop. This is done using a special adapter. When using adapters, in particular analogue, the initial image quality is lost. This is an occasion to avoid them.
  • Mainly use HDMI cable. If the cable is corporate, then it will cost expensive at the expense of the name of the brand. He transfers the image without losing its quality.

It is recommended if necessary to purchase an audio cable. There are computers and TVs that are joined to transmit audio or video files using one cable. However, most equipment requires separate cables for audio and video.

Using the diagram at the top of the window, you can drag the monitors to your liking. If not, then you just have to work manually. Here you can change the resolution from the opening list, there will be a “recommended” resolution, but it may be wrong, try the above resolutions in order and see if they improve them.

Connecting the device via Scart connector

This can lead to the fact that part of your desktop will be out of the screen or a black frame around everything. Your laptop can still cause problems, so you may need to fix the problem here. Depending on the age of your laptop, this can be eliminated by changing the settings in your graphic drivers.

When using the HDMI port to connect devices to each other, a special adapter is not required. This is due to the fact that the HDMI port transfers both video and audio signals. With a different type of connection, you will need to purchase a separate cable.

In the laptop, the output for audio is 3.5 mm, and marks the icon with the image of headphones. It is possible to connect an audio cable to the TV, if he has an entrance for audio, or to external columns (an amplifier or receiver will help).

In the process of connecting the audio cable, you must verify in accordance with the audio entry and video of the output.

Connection of the laptop to the TV: Stages

Consider the answer to the question of how to connect a laptop to a TV. In principle, there should not be problems with modern technology models. The peculiarity of modern video cards is that you can connect even a few displays. For older models, you will have to purchase an additional cable “for sound”. Connection algorithm:

  • Before the direct connection of one device to another, you need to make sure that the laptop is turned off. This is required when connecting through older types of connectors. Connection through the exit HDMI such a manipulation is not required;
  • you need to connect both ends of the wire. Then you need to install the necessary signal source on the TV. Most inputs on this device have marking. In the menu you need to select the entrance to which the laptop is attached. If there are doubts, then you need to carefully study the instructions for the TV; Note: the TV needs to be left on. This is necessary so that the laptop will recognize it as its monitor.
  • If the laptop was turned off, then you need to turn it on. Now the TV as a monitor for a laptop will work depending on the operating system. In some cases, the picture may be displayed immediately, the image can be duplicated (to be on the laptop monitor and on the TV). There are times when the picture on the TV screen is completely absent;
  • The next step you need to connect the TV as a monitor. Some laptops have a separate button to control the monitor. It can be used by pressing the “Functions” key (FN). This button is designed to switch all available options to display the picture on the monitor.

There is a function of expanding images at once on both screens, as well as the inclusion of one of them. The owners of the Windows 7, 8 operating system have the opportunity to call the “projector” menu (Windows P). Using this menu, you can choose any of the above methods for displaying the image on the screen.

If it is impossible to use any of the listed options, you need to click on the laptop on the work table, and select the “Properties” tab in the window that appears, then select the “screen resolution”. Use the function of “several screens” to select the way to display the picture that is right for you.

A large number of modern high.resolution TVs can be reproduced in a resolution of 1920×1080. However, some have restrictions in resolution 1280×720 or 1366×768. The ratio of the parties with such a resolution is wide.screen (16: 9).

If there is no normal image, you can turn off the devices from each other for a while, and re.set the resolution settings before re.connection. When choosing the function of duplication of the image, it is worth remembering that the resolution of the monitor must correspond to the resolution of the TV.

It is necessary to set the scaling of the TV screen. Some models are trying to adjust the different ratio of the sides of the screen, using the scaling of the image. If the “cut” edges are noticed, then you need to check the connection of this function.

  • When connecting devices to each other with high screen resolution, the ability to see some elements will only be on the HDTV monitor, but not on the laptop monitor. This feature is quite normal. To observe the same elements on the computer again, just turn off the TV.
  • It happens that difficulties arise when connecting wires. In this case, you can purchase a device that transmits a signal without wires. It is quite simple to use and ensures the absence of unnecessary cables.
  • If you have problems with sound, you need to try to switch it from a laptop to a TV using a special sound card utility. To do this, you need to find the logo of the sound card in the control panel, accompanied by the inscription Audio.

All of the foregoing will help solve the issue of how to connect a laptop to a TV.

Extra options

Having finished with permission. go to the menu of additional parameters on the Monitor tab.

Set the update frequency supported by your TV.

To do this, use the opening list of the “screen update frequency”.

Then set the color rendering parameter “True Color (32 bits)”.

Do not forget to select a TV connected to the computer in the “Monitor type” section.

With each change in the settings, a window will appear in which you can both use and cancel the variable parameter.

Therefore, the everyday life is attentive and if the image on the TV screen becomes incorrect. make the cancellation.

Using a laptop as a monitor for a computer

Today, almost every house has a stationary computer, and besides it, a laptop, tablet and other devices is also. Even one modern person accounts for several devices that serve for different tasks. Any technique cannot function forever and sooner or later fails, sometimes having served its own, sometimes ahead of schedule. But what to do if at the most inopportune moment the computer monitor brought? The situation is uncritical when the devices are interchangeable, but in some cases the use of a laptop instead of PC is not a solution to the problem, for example, if there is any important information on the hard disk, it is necessary to continue work, complete the project, etc.D. There are different methods of transferring data when the necessary information is captured by the system unit, the option using a laptop as a monitor involves obtaining information without extracting stiff drives. It also happens that there is a need to connect a second monitor, which is not available, for example, for stream or other purposes. The reasons why the user wondered whether it is possible to use a laptop as a monitor can be different.

When connecting a large display to the laptop, the latter will act as a system unit. For this process to be successful, you should carefully consider the connectors on the laptop. And depending on this, choose the corresponding cable.

Through HDMI

This is the most common type. You can usually find it on the portable PC and on the monitor. If you find on both devices, hurry to the store and buy a cable with HDMI outputs at the ends.

Put a Desktop GPU in a LAPTOP… The CHEAP WAY!

By connecting the connectors using a cable, you will receive the transfer of the image from the laptop screen to a computer monitor.

On older devices, there may be VGA connectors. They are outdated, but also workers.

If you have just such, purchase a special cable.

Occasionally in laptopes there is a DVI output.

If the monitor is the same, then you can easily connect to it using a cable with a similar connector.

Display Port

Mini Display Port look for game beech.

By connecting with this connector to a large monitor, you can overcome new levels in games with special convenience.

USB port

In expensive ultrabook models, the above connectors are not provided. But this does not mean that you can’t connect. You can do this using the USB Type-C port.

One trouble: monitors are very rarely equipped with a similar port.

Connecting by adapter

It may happen that the connectors on the devices do not match. What to do? Abandon the idea of ​​connecting? In no case. You just need to purchase an appropriate adapter, and then the process of obtaining an image on another medium will be successful.

Problems with connecting an HDMI output with a DVI input through the adapter should not arise. But the VGA entrance is not digital, so, using an adapter, image quality can worsen significantly. If there is another opportunity, this type is better not to use at all.

We connect the monitor to the laptop via HDMI cable

It is recommended to turn off both devices before connecting the cable. Honestly. I do not turn off until nothing burned out. But I recommend turning off the laptop and disable the monitor power.

We connect the second end of the cable to the laptop.

After connecting (and turning on), the image will most likely be duplicated on both screens (as in the photo below).

Update: There are many monitors with speakers. By HDMI, the cable can be transmitted not only the image, but also the sound. If the sound to the monitor did not go immediately after connecting, then perhaps you need to change the sound playback settings in Windows.

Then you can change the operating mode of several displays. Windows has 4 modes:

  • Duplicate, or repeated. This is when the same image is displayed on the screen of the laptop and monitor.In this mode there is one nuance with screen resolution. It is determined by the lowest resolution and is installed on both screens. On laptops, a resolution is usually 1366 × 768, and on 1920 × 1080 monitors. In this mode, a resolution of 1366 × 768 will also be forcibly exhibited on the monitor. And the picture will not be of very good quality. In my case, the laptop is also 1920 × 1080.
  • Expand. When the second screen becomes a continuation of the main.You can take some shortcuts, windows, etc. D. You can, for example, work on the laptop screen in the browser, and take the player on the monitor and watch the movie. Or open the same YouTube in another browser window.
  • Only computer screen (turn off the vice.rector). This is when the image is displayed only on the laptop screen. The monitor is disabled.You can turn off the monitor without disconnecting HDMI cable.
  • Well, the last mode is only the second screen (only the projector). Here is the opposite. The laptop screen is disabled, and the picture is displayed only on the monitor.

How to change these modes and, if necessary, change the resolution in Windows screen parameters, I will show further in the article. Separately for Windows 10 and Windows 7.

Monitor setup (second screen) on a laptop with Windows 10

To quickly change the way to display the image, just press the combination of Win P keys on the laptop keyboard. Or use a special functional key. Most often paired with the key fn.

A menu should be displayed on the screen in which you can already select the desired mode.

If these settings are not enough for you, then you can open the “screen parameters”. By pressing the right mouse button on the empty area of ​​the desktop.

Two displays should be displayed there.

They can be selected and changed for each separately. Including you can change the screen resolution. There you can also choose one of four options for working with two displays.

Everything seems to be simple and clear there. I think there is no need to describe each settings item.

We change the parameters of several screens in Windows 7

In Windows 7, you can call the menu by pressing the combination of the key p. It looks like this:

You can open more advanced settings. To do this, click on the desktop with the right mouse button and select the “screen resolution”.

We will see that two screens are displayed. Monitor and directly laptop screen. They can be determined by pressing the corresponding button. Also choosing a certain screen, you can change its resolution and orientation. Or change the operating mode of two screens.

This information is enough for you to connect your monitor to the laptop and enjoy the image on the big screen. Work for a monitor, play games, or watch movies is much more convenient. And turning off the laptop from the monitor, you can move to the sofa, or go to the nearest cafe and continue to work for a cup of tea. Full freedom!

If you can’t decide on the connection integer, or you have other questions, then leave them in the Комментарии и мнения владельцев. Just definitely write a laptop and monitor model.

How to connect a laptop as a monitor. practical tips

Sometimes there is a need to use a laptop as a monitor. One of the reason may be a malfunction of the main monitor, which is used on the system unit. Thus, if you are faced with this problem, be sure to read this article.

The most popular and affordable way is to connect a laptop as a monitor via cable connection. As you know, most laptops are equipped with two ports. HDMI and VGA. Nevertheless, if your system unit does not have a HDMI port, then use connecting via VGA cable.

How to connect a laptop as a monitor via HDMI and VGA

After you decide on the processor connection method to the laptop as a monitor, you need to perform a number of instructions.

  • Then you need to start the laptop and wait for the desktop. On the desktop, click on the right mouse button and select the “screen resolution”.
  • A window with screen settings will appear. In the “screen” column, select the required screen, and then set the corresponding resolution and set the function of expanding the screens. After that, click on the “OK” button.

At the end of the manipulations done, you will see that now you can fully use the laptop as a monitor. Thus, you have no need to buy a new monitor for a system unit, or now you simply do not have enough funds for a new monitor and the use of a laptop, as a monitor is a temporary phenomenon for you.

Vga (aka d-sub)

An old acquaintance of a 15-pin connector, which has been used for more than 30 years to connect monitors according to the VGA standard.

This connector is present for almost 85% of laptop and netbook models.

The modern connector, which is designed to transmit video images to digital display devices, such as liquid crystalline monitors, televisions and projectors. Designed by the Digital Display Working Group consortium.

Such a port is found on some models, but not often, unfortunately.

There is another option with S-Video, but I met a laptop with such a connector once in my life in 2008. I haven’t seen it anymore. He looks like this:

.And so that it has “tulips” or ancient Scart. this is generally on the verge of fantasy. Of course, you can use different “cunning” transforming cables like VGA. Scart, VGA. RCA. But I will not consider such options, since this option is more costly, because such a cable is expensive. Yes, and they will die with him much longer.

In any case, one of the above connectors must be on your laptop or computer. this is an axiom.

We transmit the image from the laptop to the TV via HDMI

To do this, we need a regular HDMI cable of the desired length:

We connect one end to the laptop connector, and the other. to the TV, which can have such ports up to 5 pieces:

Therefore, remember his number, so that later, when choosing an image source, put it correctly in the menu for choosing an image source:

With this scheme, the sound is also transmitted via HDMI to TV. And if a home theater is connected to it

Combine a laptop and a TV via VGA (D-Sub)

For this option, you need such a cable:

Be sure to make sure that there is a VGA separation on the TV, because on some brands and models it may simply not be. As a rule, it is marked either simply “PC” or “RGB (PC)”. It will also be called in the menu for choosing source of video signal on TV. After connecting the devices, on the TV you will only see the image, the sound will still be only on the laptop. This is because the sound is not transmitted through the VGA (D-Sub) connector.

We connect the laptop to the TV via DVI

The cable for this type of connection is used this:

Otherwise, everything is almost identical to the VGA option.

Connection Settings:

After we connected the TV through the laptop, to switch the image between these two screens is carried out by a special button. Manufacturers do not have the standard, so it all depends on the brand and model of the laptop. You need to navigate the icon:

As you can notice from the photo, this button is functional, that is, combined with one of the keys F1, f12. That is, in order to use the function of switching monitors, you must click the FN button and the icon button. A single press will switch the image from the laptop screen to TV. By pressing the buttons again, you will return the image back to the laptop monitor.

To force both screens to work at the same time, in the operating systems Windows 7 and Windows 8, you need to click a combination of Winp buttons. This menu will open:

Select the option “duplicate” or “expand”, depending on the effect that you want to get.

The same can be done through the screen resolution settings. To do this, on the desktop right on the desktop and in the context menu, select the “screen resolution” item:

In the line “Several displays” select the value “expand these screens”. In this case, the TV will be used as an additional monitor to which you can send, for example, a video player.

Or you can choose the option “Duplicate these screens”:

Then all the actions on the laptop screen will be duplicated on the TV screen. This is how the video games usually do.

Note: Due to the fact that the screen resolution of both devices is different, after their connection you may have to adjust the screen resolution for the TV.

Image and sound setting

After connecting through the adapter or using only a cable, you need to configure the connection in the TV and on the laptop.

On some models there is no menu with signal sources. Typically, tulips (RCA) or SCART connector are used on such devices for connection. If you managed to install the connection (for example, through the vga to RCA or to scart), then try to switch the source using the “TV/Video” or “AV/TV” button.

If the signal source is selected correctly, the laptop desktop will appear on the TV screen. For convenient work, it is necessary to make a small setup.

Since now you have two displays, you need to choose the regime of their interaction. Four options are available:

  • Duplication of the picture.
  • The screen expansion. the desktop is divided into two parts, one of which is displayed on the screen on the screen, the second. on the display of the laptop.
  • The display of the desktop is only 1. the picture only on the laptop.
  • The display of the desktop is only 2. the picture only on the TV.

The same modes are available on Windows 8 and Windows 10, so the setting is no different. In addition, to switch between screens, you can use the functional keys of the laptop. For example, ASUS computers have a combination of FNF8.

The image setup is completed, but there is still a sound. Simultaneous transmission of audio and form is possible only through HDMI. If a VGA cable or adapter is used to connect, then tulips are needed to transmit sound. In any case, on the laptop, the setting will be the same:

  • Click on the dynamics in the field of notifications and open the list of playback devices.
  • With the right button, click on the connector through which you connected the laptop to TV. Select “use by default”.

Now the sound will be sent to the port you specified and further to the audio system TV. If there is no desired connector in the list of playback devices, then you need to click on the free place and select “Show the disconnected devices”. If the connection is installed correctly, the connector will definitely appear, it remains only to choose its use by default.


If you have a card from Nvidia, then you can switch the integrated video card to a discrete on a laptop using the Control Center utility. Initially, it is installed with the drivers, but if it is not, then you need to update the drivers and you will have it. The utility is automatically built into the context menu and you can open it with one click.

A window will be displayed in which it is necessary:

  • On the left side of the panel, go to the menu “Parameters 3D”;
  • Further in the “Parameters Management”;
  • Next, select the application from the list that should be launched from the external card; If it is not on the list, then click on “add” and find it manually.

The switching process is always one and does not depend on the manufacturer of your laptop, whether it be, asus, acer, samsung, hp, dell inspiron, lenovo and p.P, and from the Windows version (7, 8 or 10).

Pros and cons of discrete graphic adapters

Installing a discrete video card on a computer or laptop can be due to the following advantages:

  • The possibility of using resources of two video cards at once at the same time (a function that PC owners with Windows 10 and DirectX 12 will be able to use in the future).

How to Setup External Graphics Card on a Laptop for CHEAP !!. eGPU Tutorial

At the same time, a discrete video adapter has certain disadvantages. First of all, this is a high price. The minimum cost of a modern graphic card, which allows you to run more or less demanding on the resources of the game, begins with 100-150, more powerful models can cost more than 1000.

In addition, a discrete adapter increases the power consumption of a computer. sometimes by 50–70 watts, for some models and 300–400. And the noise from the working fan necessary for cooling the video card can be much stronger than from the cooler of the power supply or processor.
