How to connect a laptop monitor to another laptop

We use built-in utilities

If both computers are connected to the same Wi-Fi network, then you can connect the two devices using the Internet. Windows 10 has a screen projection feature that uses the Miracast standard. Therefore, first find out if your device supports this technology.

connect, laptop, monitor, another

To connect, follow these steps:

  • Right-click on the “Start” menu in the lower left corner of the screen and select “System”.
  • Further in the left menu find the section “Projecting to this computer”.
  • Adjust the parameters as you wish. For example, a PIN code and the need to enter it every time you connect.
  • Then, on the desktop computer, press the WIN R key combination and enter the mstsc command.
  • In the field that appears, enter the name of the laptop.

You can learn more about this method about Honor in our other article. Don’t be discouraged if you can’t connect the first time. Because there are a huge number of factors that can hinder a successful connection. For example, firewall settings, antivirus software, disabled service, and so on.

How to use a laptop as a monitor?

Just connect with a cable? No, it won’t work that way. We tell you how to do it right.

An old laptop can always be used. For example, connect it as a second monitor on a PC (yes, you can also connect it to the main one) We will tell you about several ways how to do it.

Why you can’t connect the monitor with a cable?

The vast majority of laptops are equipped with a video interface. This is usually VGA or DVA. You might think that it is enough to connect the computer and the corresponding connector with a cable. This is not the case. Do not forget that such video interfaces are video OUTPUT, that is, the signal is broadcast FROM the laptop.

Only some premium models have video INPUTS that act as signal receivers. Some laptops also have a corresponding switch, which is located near the connector, but such chips are quite rare. Therefore, in most cases, you will not be able to transfer a picture from a PC to a laptop using a regular cable.

We use remote control utilities

We can also recommend a universal method for all platforms. a remote control utility such as TeamViewer. In this case, it does not matter at all what operating system you have and how you are connected to the Internet. And you don’t have to use the most popular product. You can use any analogue: AeroAdmin, AnyDesk, RemotePC and others.

In order to use the services of most of these programs, you will need to know the laptop ID and the specified password. Of course, the software must be installed on both computers. Also, many products are free, do not require additional configuration and are translated into Russian, which makes this method itself simple and convenient.

Is it possible to connect a Mac as a monitor?

For owners of “apple” devices, a similar function is also provided. It’s called Back to My Mac, which works through iCloud. Starting with macOS High Sierra, access to the remote connection setup is carried out through the “Sharing” window.

We connect a second monitor or TV to a computer and laptop

Working on a computer with several windows open at the same time is not very convenient. Especially if you are using a laptop with a small screen for work. However, it’s easy to simplify your work by simply connecting a second monitor to your computer and you can conveniently place the windows you need on both screens.

A second monitor or TV can be connected to almost any laptop or desktop computer, and it’s easy to do. Here’s a quick guide on how to do it.

What cable is needed to connect a computer to a TV or second monitor?

The most common connectors on laptops and desktops for connecting a computer to an additional display are:

  • VGA (transfers video only)
  • DVI (transfers video only)
  • DisplayPort (transmits video, usually transmits audio)
  • HDMI (carries both video and audio)

Here’s what these connectors look like on computers, monitors, or televisions:

The most popular connectors for connecting a computer to a monitor or TV

If both the computer and the monitor (or TV) have one of these connectors (both the computer and the monitor have the same connectors), you only need the appropriate cable (VGA, HDMI, DVI, or DisplayPort cable) to connect the computer to the second monitor.

If your computer and TV (or monitor) have the above connections, but they are different, you can probably also connect only those you need an adapter:

A more complicated situation arises if the computer has only a VGA connection, and a monitor or TV has only an HDMI connection. Then a simple adapter cannot be found and in many cases it can be difficult to connect from one connector to another. this requires an expensive and complex adapter.

What needs to be installed on a TV or monitor when connected to a computer?

To view images from a computer when connecting a TV to a computer, you must select the appropriate source (input) in the list of TV video sources. Usually the source name is the same as the connection name (for example, HDMI source). The same should be done on the monitor if it does not start to automatically display the image.

Video source selection button on the TV remote

In most cases, as soon as you connect a second monitor or TV to your desktop or laptop, your computer will immediately “know” what to do with it and start displaying an image on it. However, even if an image is displayed, you may need to select how images are displayed on screens.

To allow your Windows 10 computer to manage display settings, in an empty area of ​​the desktop, right-click and select Display Settings from the pop-up menu

In the settings window that opens, the most important are the following three sections (marked with numbers in the figure):

  • 1. If two screens appear in the picture, it means that the computer has already registered the second monitor or TV. Number 1 is usually marked on the main screen (e.g. laptop).

If the second screen is on the first one on the right, you can use the mouse to move the screen shown in the figure from left to right.

If the second screen is located above the first, then the second screen in the image can be moved with the mouse above.

Since there is no inconvenience when moving the mouse from one screen to another, the mouse pointer or cursor will not appear on the side you expected.

  • 2. If you are not sure which screen is marked with number 1 and which is marked with number 2, press the “Identify” button, the display will show the number.
  • 3. On multiple displays, you can choose what you want to see on each of the screens:
  • Selecting Duplicate These Displays will display the same image on both screens.
  • Selecting Expand These Displays will display a different image on both screens. For example, you can open one document or application on one screen and another on another. You can drag each window from one screen to another using your mouse just like you drag a window on one screen from one location to another.
  • If you select Show for 1 only, the image is only displayed on screen number 1.
  • If you select Show 2 only, the image will only be displayed on screen number 2.

When you disconnect the second monitor or TV from the computer, all windows will automatically return to the first monitor. And then reconnecting the second monitor will automatically enable the options you selected when you used multiple monitors at the same time. Thus, you do not need to adjust or remember the same settings every time.

Frame width

When buying a new monitor, you should also consider the thickness of the screen bezels. Side by side, two monitors with ultra-thin bezels let you focus on the game and immerse yourself in the action. If your monitor has regular bezels, then the optional thin bezel monitor will greatly improve your view.

Do I need a second monitor?

Connecting a second monitor to your computer speeds up many tasks.

You get extra screen space to open twice as many windows, so you don’t have to constantly switch between applications. This will be useful for representatives of many professions. engineers, editors, video designers, etc.

For the gamer, this means that now there will be no need to constantly minimize the game and open applications. The second screen can be used to surf the web, watch videos, or display guides and other information for the game. Having two screens is almost essential if you’re planning to stream Twitch. you will be able to easily view the chat and reply to your viewers in real time.

For fans of racing games, it is possible to connect curved and flat monitors at the same time. Curved monitors for a wider viewing angle and immersive gaming experience.

BenQ EX3203R with very thin bezels and 1440p resolution could be a good addition to the existing screen.

Screen size and refresh rate

When buying a second monitor, you should also consider the characteristics of the monitor you already have.

Many users don’t mind monitors of different sizes, but for a more balanced experience, it is better to purchase two monitors of the same size. Ideally, both monitors should be on the same level and have the same contrast.

When it comes to refresh rates, most gamers have no problem managing two screens at different refresh rates. Monitors must be properly configured for maximum performance

How to connect a second monitor to a computer or laptop?

If you are thinking about using two monitors at the same time when one monitor is used for gaming and the other. to run various applications, then this article is for you. In this article, we will discuss the benefits of using dual monitors and what to consider when buying a second monitor.

PC connection

Make sure that your computer, or more precisely, your computer’s video card, can support two monitors at once. If your video card has only one video port, then you cannot use two monitors without purchasing an additional video card. However, most modern computers have at least two video ports, which means that two monitors can be connected. These ports can be of any type. VGA, DVI, HDMI, Type-C, or DisplayPort. If the second monitor and video card have different connectors, you will have to use an adapter.

READ  Narrowed Screen On Laptop What To Do

Considerations when working with two monitors?

Before going for a second monitor, pay attention to several aspects: the interface of the computer or laptop connectors, the characteristics of the monitor you have, and the width of the bezels and mounting options.

Mounts and stands

Depending on your purpose and application, you may need additional monitor accessories such as a stand, mount or bracket. You should also consider whether you need the ability to mount the monitor on a wall. In this case, be sure to check if the monitors support VESA bracket.

❷ Decide on the interface. choose a cable (and possibly an adapter)

If you don’t have an external monitor yet. and you are just going to buy it. then everything is simple for you: look what interface is on the laptop and buy a monitor compatible with it. How to choose a monitor, told here in this article.

If you already have a monitor and a laptop (the most common option), then first you need to see what ports are present on them. In my case, the monitor had DVI and VGA ports (see photo below ).

Ideally, if you have an HDMI port on your laptop and monitor, then all the connection for you will be carried out using one cable. In fact, you only need to connect it to the laptop port and to the monitor port.

Be careful with HDMI as the port may burn out when hot plugged!

On my laptop, there was only an HDMI port, and on the monitor VGA and DVI. which means in this case it was impossible to do without adapters.

Today, there are a lot of different adapters on sale: now you can connect almost anything that is suitable to anything ;. I, of course, exaggerate a little. but nevertheless.

❸ We connect the laptop to the monitor. we get the first picture

By and large, there is no difference whether to connect a TV or a monitor to a laptop. The steps are the same everywhere.

If we are talking about a TV or a stationary PC, I generally recommend unplugging it from the outlet (and also disconnecting the cable from the cable TV).

The point is that the HDMI port can burn out if you plug it in “hot” (as you can do with USB ports). than once there was enough residual electricity to disable the HDMI port.

2) Next, connect the cable to the monitor and laptop (if adapters are used, connect them as well).

VGA cable from the monitor: we connect it to the adapter, and the adapter to the laptop

3) Then turn on both the laptop and the monitor (or TV).

By default, the first time you connect, the image should be fed immediately to both an external monitor and a laptop screen (example below).

If you have a modern integrated video card from IntelHD (AMD Ryzen) with updated drivers, then you won’t even need to configure anything. the picture will immediately appear on the screen of an external monitor!

For owners of discrete video cards from AMD and NVidia. sometimes it is necessary to update the video driver (for example, an error may pop up that the video signal transmission is impossible.).

The monitor is connected to the laptop. the picture is the same here and there

❶ Connection interfaces

I think the article should start with the interfaces that are most often found on monitors and laptops. And it is with them that they usually face when deciding the connection issue.

VGA (D-Sub)

Quite old already interface, but still popular. Millions of technology supporting VGA have been released, and therefore, it will be relevant for a long time (albeit morally outdated.). Occurs even on newer laptop / netbook models.

Cons: max. resolution when connected via VGA. 1280 × 1024 (although in many cases it is possible to transmit a picture with a resolution of 1920 × 1080 pixels (and even higher), this possibility depends on the equipment).

Cannot transmit audio signal. Mainly suitable for simple projectors, video consoles, small office monitors.

The interface is very popular, although it is even less common on laptops than VGA. Available in one- and two-channel versions, they differ in max. resolution that can be transmitted. 1920 × 1080 and 2560 × 1600, respectively.

  • DVI-A. for analog signal;
  • DVI-D. for digital;
  • DVI-I is universal. By the way, there are technologies for transferring images to 4K monitors by connecting two cables.

Note that the various connectors and their configuration (DVI-A, DVI-D, DVI-I) are compatible with each other (note: however, there is a difference in the pins involved).

One of the most modern connection interfaces. Ideal for connecting TV, monitors, set-top boxes to a PC or laptop.

Allows transmission of both video and audio signals. This interface is found in almost every laptop (also found on tablets and mobile gadgets).

Supports FullHD (1920×1080) picture, 3D, max. resolution up to 3840 × 2160 (4K). In general, today it will suit almost every user.

Note that HDMI comes in several sizes: standard, mini, and micro. Laptops (overwhelmingly) use the standard size type.

Display Port

A new interface that is gradually gaining momentum. Has high bandwidth, transmits audio and video signals, supports 4K and FullHD resolutions, picture in 3D.

Allows you to connect several monitors at once in a chain (especially important for a laptop, where, usually, there is only one port).

Please note that some small gadgets have a mini Display Port (see screen below ). I note that on ordinary monitors and laptops, most often, standard-sized ports are used.

❹ Making detailed adjustments to an external monitor, projecting an image

To fine-tune and fine-tune the operation of an external monitor, the laptop keyboard (usually) has a special function key.

For example, on my ASUS, the FNF8 key combination is used for this (pay attention to the picture on the F8 key. On different laptop models, there may be excellent keys ).

If you don’t have such keys, try the WinP combination, and also read below, there will be a second option, how you can get to these settings.

When you press this combination (FNF8 / WinP). Windows 10 shows a small pop-up window on the left of the screen, in which you can select several projection options:

  • only computer screen. the image will be displayed only on your laptop screen (convenient when you want to show a presentation, but are still preparing materials. Or, say, for work, you do not need a large screen yet);
  • repeating. the same picture on an external monitor and a laptop screen (see my photo above );
  • expanding is an interesting solution: in fact, you will have a large desktop for 2 screens at once. On one screen, you can start watching a movie or show some kind of graph, and on the other screen, you can do something else, say, type text or play a game;
  • only the second screen. on a laptop the screen will go out, on an external monitor it will work. Convenient when at home (say) you connect a laptop to an external monitor and work (i.e. you will have a laptop as a system side).

The photo below shows the option when only an external monitor works (the last option).

If special. you do not have keys on the laptop keyboard (or they do not work). then in the new Windows 10 OS you can resort to another setting option.

Right-click anywhere on the desktop, and in the menu that appears, select “Display Settings” (see screenshot below).

Next, I should open the “Display” section of the Windows 10 Control Panel. In this section, you can do 2 important things:

  • adjust scaling: often on laptops with a small screen, but high resolution, scaling is enabled in the region of 125-170%. Naturally, on a regular external monitor. the image will be too large and not very comfortable to look at. Therefore, adjust the scaling specifically for your monitor and your vision;
  • multiple displays: here you can choose the projection option (what was discussed above: i.e. show the picture on both a laptop and a monitor, or only somewhere in one place).

But here I would also like to recommend you two more of my articles on similar topics:

  • How to find out and change the screen resolution or why everything on the monitor screen has become large;
  • Eyes get tired when working at the computer. how to set up the monitor correctly.

How to connect a monitor to a laptop [step by step instructions]

Many laptops are now catching up with PC performance. Perhaps the only thing they sometimes lack is a large screen.

But this can also be solved by connecting a second external monitor to it (I note that now even thin ultrabooks support this feature).

In this article, I will analyze the main points and questions that often arise when solving this issue. I think the information will be very useful for everyone who is interested in this topic.

I have an article on my blog about choosing a monitor for a computer (the article also talks about a laptop screen).

USB Type-C (Thunderbolt)

Over the past year, the universal USB Type-C port has been actively gaining popularity. And this is not surprising. judge for yourself, with the help of it you can transfer data, video and audio signals to the monitor, plus simultaneously charge the device from it (if it is a laptop). It’s mega-convenient because just one wire!

USB-C port on top. for data transfer, from below. Thunderbolt 3

True, one important “footnote” should be made here. the fact is that not every USB Type-C is “able” to do all this.

READ  What to do if the laptop gets too hot

In order not to get confused, read carefully the description of the device and see the labeling of the icon next to the port. In total, there are three main types of USB Type-C:

  • normal (): simple data transfer is possible (found on both monitors and laptops);
  • with the possibility of transmitting video and audio signals: this port is marked with a “DP” (Display Port) icon. Sometimes, instead of the “DP” abbreviation, there may be a monitor icon;
  • if there is a lightning bolt next to USB Type-C, then the port supports Thunderbolt ().

By the way, pay attention not only to the ports of the video card (laptop). but also to the monitor itself. Not every monitor with USB Type-C supports video signal reception (it is best to rely on the device specification).

Interfaces for connecting a monitor to a laptop

In order to connect a monitor to a laptop, you first need to carefully examine your laptop in order to understand what ports (interfaces) for displaying images it is equipped with. Consider the most popular interfaces for connecting monitors to a laptop.

VGA is the most common interface and can be found in almost all laptops. VGA is a legacy analog interface. Nevertheless, it is still quite relevant and can be used to connect a monitor or projector to your laptop without any problems.

HDMI is also a very common interface for connecting a monitor or TV. Often used in conjunction with VGA. Also, the HDMI port can often be found on other computer equipment. For example, on tablets or smartphones.

DVI is a rare used option for connecting a monitor to a laptop. DVI is considered the standard for connecting monitors to desktop computers, but it is rarely used in laptops.


DisplayPort is one of the newest interfaces for displaying images. DisplayPort has been rapidly gaining popularity lately and is increasingly found in laptops.

After you have examined your laptop and determined what interfaces it is equipped with for displaying images, you need to do the same with the monitor. In general, you need to find the interfaces that are on both the monitor and the laptop. With their help, you can connect the monitor to your laptop.

In order to connect a monitor, you just need to connect two identical ports on the monitor and on the laptop using a cable suitable for the ports. After that, the laptop should detect an additional monitor and a picture from the laptop will appear on it. If after connecting the monitor is not detected, restart the computer.

How to connect a monitor to a laptop

Modern laptops are practically not inferior in performance to full-fledged desktop computers. At the same time, the laptop user is not tied to one point and can freely move with his PC. Therefore, recently more and more people prefer to use a laptop as their main computer.

However, for home use, the laptop has one drawback. the small screen. To neutralize this problem, a full-fledged monitor must be connected to the laptop. In this article, we will tell you how to connect a monitor to a laptop via VGA, HDMI, DVI or DisplayPort cable.


Also, a situation may arise when you do not have the same ports on a laptop and a monitor. For example, a laptop has only an HDMI port, and a monitor does not have an HDMI port. In this case, you will need adapters.

Now you can find an adapter from almost any interface to any:

  • DVI. VGA;
  • DVI. HDMI;
  • HDMI. VGA;
  • DisplayPort. DVI;
  • DisplayPort. HDMI
  • etc.

Configuring monitor connection to laptop

After you have connected the two ports, a picture from the laptop should appear on the monitor screen. However, it is not always convenient to work in the duplicated screens mode. To change the mode you need to enter the “Screen Settings”. To do this, right-click on the desktop and select “Resolution”.

In the window that opens, you can select the mode of displaying the image on the connected screens. The following modes are available:

  • Duplicate screens. In this case, both screens will work simultaneously, both on a laptop and on a monitor. In this case, the picture on both screens will be the same. This mode is especially useful when connecting a projector or monitor for presentations.
  • Extend the screen. In this case, the connected monitor will expand your laptop’s screen. By choosing this mode, you can work with two screens at once and move windows between them.
  • Show desktop only 1 (or 2). In this case, you select only one of the screens. While the second monitor will not work. This mode is suitable if you only want to work with a connected monitor.

the screen is broken, on a laptop there is a monitor with a VGA output, I connect it. writes no signal because it is not configured in the settings of the video card, and the display on the laptop is completely broken I can not configure how to solve all this? is it possible?

Perhaps the laptop has other breakdowns besides the screen. Since in most cases, the picture on the monitor screen appears immediately after connecting the monitor, without any adjustment.

We tried to connect a laptop with a broken screen: through the cable that we bought with the PC everything works, through the cable that was purchased additionally. neither the PC nor the laptop works. The screen displays “check cable connection”. What can be in such a situation?

What are these cables? HDMI and VGA? Why the first connection option is not suitable?

What to do if yesterday I connected the laptop to the TV and he saw the screen, today the image is not displayed on the TV, what should I do? connected via HDMI

Where have you come across HDMI. VGA adapters / cables? Share the source of the working version =)

I crashed a netbook. I connected the cable from the monitor to the netbook. But then he started loading Windows. after which the screen darkened again. What should I do?

Good day! I have such a situation with a portable screen that is completely broken. I tried to connect to the monitor, in theory, on, but then Windows does not start. What to do ?

Maybe you just need to reinstall Windows. maybe the laptop is damaged not only the screen.

On a laptop, the resolution is 1600 × 900, but we want to connect to a TV via HDMI! The TV requires a resolution of 1980X1080, but there is no such resolution on a laptop! help with the problem.

Use the display mode “Show desktop at 2 only”. Then you can change the resolution to 1980X1080. If you use mirroring of screens on a laptop display and TV, then the maximum resolution will be the same as on a laptop.

Good day! And if the display in a laptop does not work, how to connect a monitor?

The monitor can be connected via VGA or HDMI. If the monitor does not have an HDMI input, then you can use an adapter. If the “Duplicate screens” display mode is enabled on the laptop, the picture should appear on the monitor immediately after connecting to the laptop. If there is no picture, then you need to change the settings. And with a non-working monitor, this is practically impossible.

What to do if a laptop breaks down in half is it possible to connect a monitor to it from a computer

In the right corner of the screen there are two squares, when you click on them, the screen should expand, if I understood correctly. I press, the screen narrows again, pressing again does the same. Only from the fifth or sixth time it is possible to turn on the normal screen. Help the teapot!

I can’t understand what you mean. What are the “two squares”?

2 squares, she means “minimize to the window”

Good day. Please tell me which adapter is better to use (for working with graphics): the monitor has DisplayPort and DVI, the laptop only has HDMI.
I think DisplayPort-HDMI or DVI-HDMI ?

It seems to me best with HDMI to DVI. These two interfaces are almost the same in terms of image transmission.

but how to set up on XP. the desktop itself shows, but there are no icons or the mouse cursor and no action occurs. Thanks in advance.

If it shows only the desktop and nothing else, then the problem is not with the monitor. It works fine. You have a problem with Windows. You may need to reinstall the system.

Please tell me, I connected the laptop via HDMI cable, turned on the mode to show the monitor screen only. But when playing games, the video slows down, freezes, what to do?

Can the laptop not cope with the resolution of the monitor? Have not tried lowering the resolution and other graphics settings in the game?

The matrix is ​​broken on the laptop. How to connect a monitor to a laptop to configure the BIOS, since the monitor turns on only when Windows starts, and when the BIOS is running, the monitor is black.

With a broken matrix, most likely, nothing will come of it.

Hello! I connect a monitor (DVI) to a laptop (VGA) via a DVI-VGA adapter, but nothing happens. The monitor writes no signal. The Fn F5 keys on the laptop do not toggle anything. Monitor Iiyama ProLite XB2374HDS, old Toshiba laptop with WinXP (in theory, it should pull). Also on the monitor is the DVI-D (single link) output, and the adapter is a standard female DVI (-A or.I). I don’t know if this matters. I would be grateful for your help.

This laptop model is equipped with a VGA (D-Sub) input. Connect your laptop to it. Why are these dances with a tambourine?

This is how I connect, through the CAA. And the laptop seems to see the monitor (two monitors are displayed in the parameters), but the monitor does not show anything. And the function to make it as main is not available. When I try to go into the properties, it says something like a problem with firewood. Along the way, you need to reinstall Windows. thank.

READ  How to make a keyboard on a Dell laptop

No, that’s not what I wanted to say. Confused a little in the previous comment.

The Iiyama ProLite XB2374HDS monitor has a VGA input. Connect your laptop to it. It will turn out VGA-VGA without any adapters.

Thank you very much)) Indeed, I somehow did not think about it) In vain I just bought the adapter. The monitor shows, but now another problem. the monitor does not give out its resolution (1920 x 1080), it shows the resolution of the laptop. In the parameters of the second monitor, I set 1920 x 1080, but it does not change (even after a reboot). The function to make the monitor the main one is still not available and it is still impossible to go into the properties (write update the display driver, although I have already updated it several times)

Oleg, you probably use the “Duplicate these screens” mode in this mode, an image with the resolution of a laptop will be displayed on the monitor. Select the option “Show the desktop only 2”, after that the resolution should automatically change to 1920 x 1080. Well, or it will be possible to set 1920 x 1080 manually. If it is not clear what I mean, then re-read the ending of this article.

With this, everything is clear, but I have Windows XP, and there it is a little different An extended (not the main one) desktop is displayed on the monitor, as it were, in the middle of the screen, not in full screen. When deploying programs on it, it becomes fullscreen, but this is not 1920 x 1080 and far from HD. I do not know if this is not supported by the CAA, or it is necessary to install Windows 7. Thank you for your attention and help.

I have no idea what to do with Windows XP. But, if the laptop can handle Win7 and there are drivers for Win7 for this laptop, then you can install. With Win7, managing connected monitors is much easier. Set “Show desktop only at 2” and everything works.

HDMI connection. excellent video. There is no sound from the built-in speakers of the monitor. Tell me the way to make a sound. THANK.

How to connect a monitor to a laptop

Users often wonder if it is possible to connect a monitor to a laptop. A large screen can either replace a small laptop display or expand your workspace. This is important for video editors, designers, layout designers, programmers, testers and other professions, where it is more convenient to work on a large display. Gamers and moviegoers can display a picture on a larger display, it is also more convenient to show presentations on it.

    How to adjust the resolution of a monitor connected to a laptop

    To change the resolution of the picture on the second screen:

    • Right-click on the Desktop and select “Display Settings”.
    • Specify the target device. click on the number 1 or 2, respectively. The “Define” option will help you select the desired display.
    • Specify permission.

    Also, programs supplied with graphics accelerators allow you to control the resolution.


    Windows provides several options for displaying images on a multi-monitor system. Setting options: repeat, expand, 1 screen only.

    Let’s look at how to adjust the image on a monitor connected to a laptop. To do this, we will use the panel with additional display options.

    On the keyboard of some laptop models there is a special function key for calling up the external monitor settings menu. It could be a combination of Fn F7 keys. F8 or other. If there are no such keys on the keyboard of your laptop, use the tools of Windows.

    How to connect 2 monitors to a laptop

    A pair of monitors can transform a laptop screen into a multi-monitor system with extended work or play space. The laptop supports a multi-monitor configuration if it has two or more video outputs (their role is also played by USB-C connectors). For example, HDMI and DVI or USB-C and HDMI indicates that the main and secondary monitors can be connected to the laptop. Ensure compatibility between laptop interfaces and connected monitors: buy the necessary wires and adapters.

    There are enthusiasts who want to know if it is possible to connect three monitors to a laptop. There are ways to do this:

    • use discrete and integrated video cards, if the BIOS allows it;
    • connect monitors to all video outputs;
    • use splitters. signal dividers. the picture will be duplicated on devices connected to one port of the laptop. The resolution on all devices will be the same, you can change the value only through the control panel of the monitor itself.

    Do not forget about the power of a laptop video card: displaying an image on two high-resolution displays is a resource-intensive task. To connect a 144Hz monitor to a laptop without losing frame rate, you need HDMI, DisplayPort, or Dual Link DVI.

    Connect phone to laptop as a monitor

    With the help of third-party applications (Splashtop Wired XDisplay, SpaceDesk), you can connect your phone or tablet to a laptop via Wi-Fi and use it as a second monitor.

    How to make a connected monitor to a laptop the main one

    Hold Win P. select the “Second screen only” option.

    Connection options

    First, look at the connectors on your laptop. On one side you will find a connector for connecting an external monitor. The most common are VGA, DVI and HDMI. DisplayPort can also be found on modern devices.

    After finding the connector on the laptop, we examine the existing monitor for the presence of a video port. it is located at the back of the device.

    Ideally, the port on the laptop should be the same as on the monitor, but if there are no identical connectors, adapters (video converters) come to the rescue. There are many adapters available from DVI to HDMI, VGA to DVI, etc. There are also universal adapters with many interfaces.

    How to connect and set up a monitor

    It is better to connect with the device turned off, since some laptops check for a second display only at startup.

    To connect, we take a cable with the appropriate connector.

    exotic option. VGA-miniVGA cable.

    Such a cable can be used, for example, to connect to a TV.

    We connect one end to the monitor, and the other to the laptop.

    Immediately after connecting, you will see the same picture on both displays. it will be duplicated (clone mode).

    However, it is not always necessary to display the same image on a laptop and on a monitor. In addition, the resolution is often chosen incorrectly, based on the lowest resolution of the two displays used. Therefore, you will need to configure.

    On the desktop, press the right key. “Screen Resolution”.

    If the monitor is not immediately detected, then in the window that opens, click the “Find” button.

    Then it is necessary to determine which of the displays is the main one, which screen will be to the right and which to the left. This can be done using the “Define” button in the same part of the window.

    Note that in the field “Multiple monitors” you can choose to duplicate the image, expand it on both screens or display only on one.

    The first option can be used, for example, when showing presentations. In this case, one of the screens is in front of you, and the second in front of the audience (often a projector is used for such purposes).

    The second is the most convenient, and therefore more frequently used.

    When this mode is selected, it becomes possible to change the resolution for each screen separately.

    After making changes, click “Ok” and get to work.

    In this mode, you can move icons and files between the two screens, which is very convenient when working with a large amount of software at the same time. The size of the foreseeable space is doubled. You can watch a movie and chat on social networks at the same time. You don’t have to constantly switch between apps. This will undoubtedly lead to an increase in your productivity.

    The third option is used, for example, if the laptop screen is faulty and you decide to use another one for your tasks.

    If you want to quickly switch between monitors, there is a WinP hotkey combination. Pressing this combination opens a window for selecting the operating mode of several screens. This is how it looks for Windows 7.

    For Windows 8 and 10, the Projecting pop-up appears on the right with the same options.

    Customization can also be done using specialized utilities. For example, if you have integrated video from Intel, then right-click on the desktop to open the graphics settings and then, as shown in the picture.

    The projector connection algorithm is similar.
