How To Connect Laptop Screen To Pc

Desktop customization

It is possible to display the image from the computer system unit on the laptop display only if you have previously configured the display of the desktop on the PC. To do this, you need a monitor, at worst, a modern TV with an HDMI, DVI or VGA connector (depending on which connection the PC monitor supported).

connect, laptop, screen

For the connection to be established, the video card in the system unit must have at least two outputs. Here is one output cable goes to a PC monitor or TV, from the second. to a laptop. Setting up the desktop is carried out on the computer, the laptop will be the second display for now.

  • Right click on the desktop. Open the Screen Resolution tool (Display Settings on Windows 10).
  • The system should detect that there are two displays connected to the computer block. You can duplicate images on them, extend the desktop to two screens, or select only one monitor.

The laptop display in this case is the second device for displaying a picture. Set the value “Display desktop only at 2” so that the image from the video card from the computer’s system unit is transferred to the laptop screen.

Such a connection is possible only if the laptop has a video input, and not just a video output. The presence of one connector for connection to the system unit is not yet to say that you can make a laptop monitor for a computer.

Using a laptop as a monitor for a computer

If the question arose of how to use a laptop as a monitor, then you should know that you will NOT be able to do this directly. Even if the laptop has a connector to which you can connect a cable from the computer’s system unit, the image will NOT appear on the display. The installed system will be displayed on the laptop screen, there will be no connection with the PC.

Remote control software

You cannot use a laptop instead of a monitor, but you can make a remote connection and display data from the computer on the laptop screen. In this case, it is not necessary to connect the laptop to the system unit, the connection is established over the network. There are several proven options to display an image from a computer on a laptop display without connecting to the system unit.

  • Zoneos ZoneScreen.
  • Radmin.
  • Teamviewer.

To configure the computer, there must be a monitor, the laptop in this case will be the second display. First, let’s see how the ZoneOS ZoneScreen program works. The application has two modes of operation. the server (the computer from which the image will be sent) and the client (the laptop, which will perceive the signal).

  • Run the program on your PC. Select the “Act as a server” mode and click “Next”.
  • Leave the port by default. 2730. It is better to set the resolution as supported by the laptop display.
  • In the next window, select the image transfer options. The higher the baud rate, the lower the latency. But as the speed increases, the load on the network and the computer increases. Set the number of uncompressed frames to 10 so that the load is not excessive. After establishing a connection, experiment with the settings, choosing the optimal parameters.
  • Click “Start” to start data transfer. If the connection has already been established, but you changed the settings, Click “Reloaded”.

Now you need to configure the client, that is, the laptop. Run ZoneOS ZoneScreen on it and select the “Act as a client” mode. Leave port 2730 and specify the IP address of the computer to establish a LAN connection. To find out the IP address:

  • Run on the PC the command term. Type “ipconfig” and press Enter.
  • Look at IPv4 addresses.

I entered the computer data in the client on the laptop, click “Next”. A window will appear through which you will see the PC desktop on the laptop screen.

If ZoneOS ZoneScreen does not work (there are compatibility issues with the latest Windows versions), try setting up remote control via TeamViewer or Radmin. The first program is distributed free of charge, in the second you need to buy a license, but there is a demo access for 30 days.

You should download TeamViewer from the official website. To make the program work for free, during installation, check the item “Personal / non-commercial use”.

To establish a connection to a remote computer via TeamViewer, you need to know the ID and password. Naturally, TeamViewer must also be installed on the computer. The process of pairing devices is extremely simple:

  • Find out the computer ID and password (just start TeamViewer on it, the identification data will be assigned automatically).
  • Open TeamViewer on your laptop. In the Partner ID line, enter the PC identification number. Enter the password to connect to the computer.

After completing this simple procedure, you will see the PC desktop on the laptop display and even be able to control it. But the computer must have a working monitor, otherwise nothing will come out.

We use a laptop as a monitor for a computer

If you need to connect a second monitor to a computer, but it is not available, then there is the option of using a laptop as a display for a PC. This process is carried out with the introduction of only one cable and a small setting of the operating system, but there is one very important remark. Let’s take a closer look at this.

Connect laptop to computer via HDMI

To complete this process, you need a working system unit, an HDMI cable, and a laptop with an HDMI-in connector. All settings will be done on the PC. The user only needs to perform a few simple steps:

    Take an HDMI cable, plug one side into the corresponding HDM-in connector on the laptop.

Now you should start the laptop. If the image is NOT automatically transferred, press Fn F4 (on some laptop models, the switch between monitors can be changed). If there is no picture, adjust the screens on the computer.

Select the “Display” option.

Go to the “Configuring display settings” section.

If the screen was not found, click the “Find” button.

You can now use your laptop as a second monitor for your computer.

Alternative connection option

There are special programs that allow you to remotely control your computer. Using them, you can connect your laptop to your computer via the Internet without using additional cables. One of the most popular programs is TeamViewer. After installation, you only need to create an account and connect. Read more about this in our article at the link below.

In addition, there are many more programs for remote access on the Internet. We offer you to get acquainted with the full list of representatives of this software in the articles on the links below.

In this article, we examined the process of connecting a laptop to a computer using an HDMI cable. As you can see, there is nothing difficult about this, if the laptop is equipped with HDMI-in, the connection and adjustment will not take long, and you can immediately start working. If the signal quality does not suit you or, for some reason, the connection cannot be made due to the lack of the required port, we suggest taking a closer look at the alternative.

Technical information

HDMI is a digital I / O port that supports bi-directional communication. Its operation is controlled by the video adapter driver. Accordingly, the first step is to update the software to the latest current version (to support the latest version of the port specification).

Some Ultrabooks that have a physical HDMI port cannot output images from another PC. This is explained by the technical limitations of the used chipset and its strapping on the motherboard.

One more nuance: you should connect with the equipment turned off (both notebook and PC). When you try to connect them “hot” there is a considerable probability of failure of the graphics accelerator (or chipset, if integrated graphics is used). Only after disconnecting the device can you connect and configure.

If the laptop has HDMI?

If the laptop has an HDMI port, then the only output is the use of special signal converters from HDMI to VGA or DVI.

But in practice, if a discrete video adapter is used, then most likely the output of a third-party image to the built-in display will be blocked (since in such laptops there are 2 video cards that switch among themselves depending on the load on the graphics subsystem).

How to connect?

It is recommended to adhere to the following algorithm (for example, Windows 7):

  • Turn off PC and laptop.
  • Connect one end of the HDMI cable to the laptop, the other to the HDMI output on the video adapter (not to the monitor).
  • Turn on PC and laptop.
  • On the PC, enter the “Control Panel”, open the “Display” menu, go to the settings.
  • In the drop-down menu “Multiple screens” select “Extend desktop” (or duplicate, create a new table. it all depends on the needs of the user).
  • On a laptop, too, go to the “Screen” settings and select “Show Desktop 1” (or “PC Monitor”. the parameter may be called this way, depending on the brand). After that, the display will show the image from the PC.
  • In most modern laptops, switching between operating modes of the integrated display can be performed using hotkey combinations. The most common combinations are FnF4 and FnF8. You can clarify in the technical documentation or on the label on the keyboard itself.

How to set up multiple displays in Windows is described in the following

Similar settings for image output can be set using proprietary graphics accelerator software (NVidia, AMD, Intel, SiS). over, in many cases there are more functions. For example, in software from NVidia, you can not only configure the output of an image to a third-party display, but also at the same time adjust its brightness, contrast, or even enable “portrait orientation” Displayed images.

After connecting the laptop to the PC via HDMI, the sound is automatically transmitted along with the video signal, and the audio card built into the PC is disabled. You can change this parameter in the “Control Panel”, in the “Sound” tab (by choosing the built-in audio codec instead of HDMI). Otherwise, the sound will not be output to the headphones or PC speaker.

Likewise, you can use your PC monitor as an additional or external display for your laptop. But in this situation, it will be easier to simply connect the monitor directly, bypassing the graphics accelerator of the personal computer.

How to output an image to a laptop via HDMI in 5 minutes

The laptop is a portable PC. But the principle of its technical structure is similar. This means that its display can be used as a second monitor for a PC.

But how can this be done? How to connect a laptop to a computer as a monitor via HDMI and are there any other options on how to display an image from a PC on a laptop display?

  • Technical information
  • How to connect?
  • If the laptop has HDMI?
  • What other options are there for image output?

What other options are there for image output?

It is possible to display an image from a PC on a laptop display not only through a cable, but also wirelessly. But only if each device has a compatible Wi-Fi adapter supporting the WiDi or MIRACAST function.

As an alternative, you can consider programs such as TeamViewer, AirDisplay (There are not only for Windows, but also for Mac OS) Radmin. They also allow you to transfer images via Wi-Fi (even if there is no WiDi support, the image quality will be low), but if there is a network connection (via a router or switch).

In total, if you have an HDMI cable, the laptop display can be used as an additional or duplicate monitor. And it works regardless of the version of the built-in HDMI port specification. In the absence of HDMI, you can use either wireless image output (WiDi) or a dedicated HDMI to VGA or DVI converter.

How to use a laptop as a computer monitor or a second laptop

There may be several situations when there is a need to use a laptop as a monitor. The most common problem is the failure of the main display of a personal computer. Therefore, in order to use in the future the power of the system unit and the data that are stored in it, you will need a monitor of the second external device. The same situation can occur when the display matrix of the second laptop does not work correctly.

How to connect a laptop as a monitor

Use your laptop as a monitor with a cable connection

Having decided on the necessary cable and established with its help the connection between the system unit and the laptop, we proceed to setting up the display. To do this, turn on the laptop and wait for it to fully load. After that we activate the “Properties” or “Screen Resolution” settings menu item (depending on the installed operating system) by right-clicking on an empty space on the desktop. In the window that opens, we see the parameters of the current display.

To use a laptop as a computer display, you need to select the required monitor by name from the list that appears. Then you need to expand the PC desktop to the connected device, set a checkmark opposite the corresponding menu item. To do this, you need to confirm the changes made by clicking the “Apply” button, and then “OK”. After performing THESE simple settings, you will be using your laptop screen as your main monitor.

The advantages of this method:

  • Reliable connection;
  • Stable data transfer rate;
  • Simple settings.

Disadvantages of cable connection:

  • Lack of required cable;
  • Mismatch between laptop and stationary PC connectors;
  • The need to purchase an adapter.

Ways to connect a laptop as a monitor

The most stable and reliable way to do this is by cable connection. Depending on the laptop model, its external interfaces may differ. You can use a laptop as a monitor through the HDMI connector or through the VGA output. If the system unit contains only an HDMI socket, and the laptop is equipped with a VGA input, then a special adapter will be required for their joint work.

How to use a laptop as a display over Wi-Fi

For computers with the operating system Windows 7 and later, as well as Mac devices, there is a special program called Air Display. It allows you to quickly and efficiently connect your laptop as a computer monitor wirelessly. To do this, the application must be installed and activated simultaneously on two devices. By following simple settings, following clear prompts, you will quickly achieve the desired result.

A stable connection of the laptop as the main display of the PC will be provided by the MaxiVista utilities. It is specially designed for this function and is available in two versions:

  • Client (for a managed device, whose monitor will be used as the main one)
  • Server (needs to be installed on the main device).

When the application starts, the server should automatically detect the client laptop. After connecting to it and performing step by step settings, you can use your laptop as a computer monitor. The main disadvantage of this utility is that it is not free and is not cheap. In addition, there are a number of programs that allow you to remotely use the display of a combined device:

  • Teamviewer;
  • Radmin;
  • Rdesktop and others.

These applications have their own characteristics and more complex configuration. Among all the listed methods, each user will be able to choose and apply in his case the most convenient and accessible option for him.

Remote access via software

And if you do NOT want to use wires, “apple technique”, you can use a special application called “Air Display”. You will need to install this software on a working laptop. This program is freely available on the official Apple website.

This method is as simple as possible, because to pair, you need to launch the program after installing it and follow the instructions, which the developer carefully equipped this software with.

If both of your devices run on the Windows operating system, then no one bothers you to install software to work with Microsoft products. The programs do NOT cause any difficulties due to their ease of use. We recommend using this particular connection method if your devices are working properly and meet the system requirements.

Modern “handmade

No one is immune from unexpected breakdowns, right? Household appliances are also NOT an exception. But did you know that technical problems can be made to work for you? It sounds pretty strange, but it is. Here we have a broken laptop, and at home a personal computer without a working monitor is waiting for us. Why not convert your laptop display to a new monitor? Why waste money?

This will require the presence of the laptop itself and, of course, desire. How to connect laptop monitor to PC? Let’s get to know this interesting procedure together, Paying attention to the most important nuances.

Your laptop has stopped working and you are about to get rid of the non-working “trash”? Don’t rush. Component parts that are still usable can always be sold or made into something interesting. For example, you can use a laptop screen as a monitor for a personal computer. Interesting, isn’t it? But how do you connect a laptop screen to a computer? We will talk about this today.

Connecting with a cable

How to connect a system unit to a laptop via vga and how to connect a laptop to a computer instead of a monitor? For the first case, you will need a connection cable, with the help of which the whole thing will be turned. Most likely, a VGA cable will suffice, but no one forbids you to use its counterparts. One of these representatives is a DVI cable. Also, this option will require an installed Windows operating system on the used personal computer.

Then you need to follow the following instructions:

  • Insert one end of the wire into the laptop connector, and the other into Connect to computer.
  • Start the laptop, wait for it to turn on completely.
  • Right click on an empty space on the desktop.
  • A context menu will open in front of you, in which you need to find and open the tab “Properties”.
  • Now you need to select the item “Display properties” and go to the section “Options”.
  • You will see a picture in front of you, which indicates the screens with numbering. Select the second screen and set the position that corresponds to the actual location of the laptop.
  • Next, mark the required item for displaying visual information with a checkmark. To select the main monitor, you need to check the tab “Use this device as primary”.

Everything is simple and clear here, but how to connect a laptop monitor to a PC the owner “apple devices”? How to display a computer screen on a laptop? You need to do the following if you have already established a connection between devices via a cable:

  • Go to the section “System settings” and find the tab there “Monitors”.
  • The same layout of display devices will appear as users of operating systems from Microsoft might have noticed.
  • Do the same manipulations for the position of the screens.
  • Save your settings and get to work.

Devices are ready to use!

Pairing devices using Wi-Fi wireless transmission

The wireless Internet has long ceased to be a rare phenomenon. So why NOT use it for this case too? Synchronization can be done by doing the following:

  • Install a program called “MaxiVista”. The software developer did not bother to create a free version, so you have to fork out a little or use a trial version of the program.
  • After installation, you need to use special modules and configure them according to the instructions from the publisher.
  • If you did everything correctly, then there will be an excellent opportunity to control screens remotely using Wi-Fi.

In what ways can you connect?

How to connect a laptop monitor to the system unit? Here we have on hand a device that once did its job properly. Its presence is enough for a very creative way out of an awkward situation. In order to start implementing this interesting plan, you need to prepare a little. First you need to familiarize yourself with the most common ways to pair two devices.

Nothing complicated, right? Now you know how to save money on buying a new monitor by taking advantage of the old technique.

Connect external monitor to laptop via HDMI port

So, we have a laptop with an HDMI port (Fig. 1).

READ  How to remove sticky keys on a laptop

We need to connect an external monitor to it using a cable and VGA connector.

To connect a monitor with VGA input, you need an HDMI-VGA adapter (Fig. 2). It is a pity, of course, that the adapter is NOT white for a white laptop, but here, as they say, it is better to have a functional and working thing than a beautiful and non-working thing. Therefore, a black adapter is also suitable.

Then connect the HDMI-VGA adapter to the laptop’s HDMI connector (Fig. 3).

In the next step, you need a wire coming from an external monitor with a VGA connector at the end, for subsequent connection to the HDMI-VGA adapter (Fig. 4).

So, We connect these 2 connectors together and Secure the connection, for which we carefully and without much effort rotate the screws located on both sides of the VGA connector (Fig. 5).

It seemed that this was all, because the monitor is now connected.

However, let’s forget that not only a video signal, but also a sound audio signal is transmitted through the laptop’s HDMI port. Therefore, prepare sound speakers for connecting them to the same HDMI-VGA adapter (Fig. 6). It is also desirable to connect the speakers in the off state, although this is not as important for them as for an external monitor.

The audio jack is located on the opposite side from where we plugged the VGA connector of an external monitor (Fig. 7).

How to connect a second Windows 10 monitor: personal experience

Next, I publish the opinion of a computer user based on my own practice.

It so happened that I am the owner of a 20-inch monitor and a 40-inch TV. I work behind a small monitor, write articles and surf the Internet. A large monitor was previously used for a console, and after that it became not in demand at all. After that I thought: “Why not get your own multi-monitor system??” This idea turned out to be not only interesting, but also quite simple to implement. It was enough to connect the TV to the video card via the HDMI cable, and the image was immediately displayed on both screens.

Computer literacy with Hope. Setting audio playback modes

After connecting and setting up an external monitor, it remains for us to adjust only the sound so that it sounds “correctly” through the external speakers connected to the adapter.

To do this, right-click on the speaker icon in the lower right corner of the taskbar. In the context menu that appears, select “Playback devices” (Fig. 12).

Next, select the connection option where our external monitor is indicated. In this case, it is an Acer monitor, so we click on the line where this monitor is indicated (Fig. 13). It doesn’t matter that in this case we connect sound, not video.

And it is important to point out that the sound should be reproduced through the port where the external monitor is connected, since we connected the speaker connector to the HDMI-VGA adapter (Fig. 7), where we also connected an external monitor (Fig. 5).

On this connection of the external (second) monitor and its settings in the Windows 10 system, in general, is completed. You can now use the second external monitor in accordance with the selected option for its connection and use.

3 Show on first screen only

This possibility is highlighted by number 3 in Fig. 11. She speaks for herself:

  • The image will be displayed only on the main laptop screen,
  • Or to the first screen of a desktop computer.

The second monitor will NOT be involved.

The meaning of this option when connecting a second external monitor is only to temporarily disable the image output to the second monitor, for example, if at the time of demonstration of the presentation the speaker decided that he does not want to broadcast some part of the video, show it to the general public.

Or it can be used exclusively for settings, when you need to temporarily turn off the second external monitor, and again show the entire image only on the main screen of a laptop (stationary computer).

Filling in the Gaps. Expanding the Horizons! Configuring Multiple Monitor Modes

The settings “Multiple displays” are especially important, for which Fig. 11 shows all the Possible options:

Consider 4 (four) options for two screens that are available in the Windows 10 operating system:

  • Duplicate these screens
  • Expand these screens
  • Show only 1
  • Show only 2

2 Extend these screens

Number 2 in Fig. 11 shows this option. It means that the continuation (to the right) of the desktop of the main laptop monitor will appear on the second (external) monitor. The desktop will become wider, as it were. It will be possible to open more windows on it so that they do NOT overlap each other.

It works this way. You open a new program, a new window. This program, this window opens on the main monitor, I close the other windows open there. Then you simply drag the opened exercise window with the mouse, not paying attention to the fact that the window will seem to go beyond the main screen to the right. This window will simultaneously appear on the second external monitor, where you can fix it, and work with this window already on the second, on the external monitor.

It is so convenient, for example, for one PC (laptop) user to work on it, and for the second, say, to watch videos on YouTube or television programs broadcast over the Internet. Also, programmers in their work often use two monitors in this mode: on one they write and edit the code (program), and on the second they immediately see the results of their efforts. This is clearly shown in the very first figure in this article.

1 Duplicate these screens

This option is highlighted by number 1 in Fig. 11. means that on the second monitor the picture will be identical to the first one. Everything that happens on the main, first monitor will be automatically duplicated on the second external monitor.

As a rule, the sizes and resolutions on the primary (first) and external (second) monitors are different. Therefore, in order to achieve the coincidence of pictures on the first and second monitors, the Windows system automatically makes the picture with the resolution, The worst of the two monitors. That is, the picture quality on both monitors will be the same as it would be on one of them, which has the worst video playback quality.

This mode is most often used for wide slideshows or any other content displayed on the main monitor.

Let’s say a presenter demonstrates slides and comments on them, and listeners see a similar image on an external second monitor. Also, often in this case, a multimedia projector acts as an external second monitor, which projects an image on a large screen for the convenience of its demonstration to the general public.
