How to connect a monitor to another monitor

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 this cannot be done 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.

Desktop customization

You can display an image from the computer system unit on a 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, monitor, another

For the connection to be established, the video card in the system unit must have at least two outputs. From one output, the cable goes to a PC monitor or TV, from the other 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 unit. 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 the desktop only at 2” so that the image from the video card from the computer system unit is transmitted 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 connecting to the system unit does not mean that you can make a laptop monitor for a computer.

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, you do not need 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 must have 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 receive 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 the connection is established, experiment with the settings to find 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 enter the IP address of the computer to establish a LAN connection. To find out the IP address:

  • Run Command Prompt on your PC. Type “ipconfig” and press Enter.
  • Look at IPv4 address.

After entering 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, the second one needs 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 ID and password of the computer (to do this, 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 work.

Physical connection of devices

The process of physically connecting the second, third, etc. monitor to the ports of the video card is not difficult. Just insert the connectors of the connecting cables into the sockets of both devices, without forgetting to first unplug them from the socket.

When creating a dual-monitor configuration, use the same interfaces whenever possible, for example, DisplayPort only or HDMI only, so that the image quality on the two screens does not differ much. If there are no identical ports on your video card, connect through different ones, for example, DVI and HDMI or HDMI and VGA. It is permissible to use adapters from one interface to another only in extreme cases, since signal conversion is always accompanied by its losses, sometimes significant. The same goes for splitters. If you can do without them, try to do.

After completing the connection, turn on the power of the system unit and monitors. Recognition of the latter, as a rule, occurs automatically. You just have to customize them to fit your needs.

Connecting a second monitor to laptops is done in the same way as to a stationary PC. The only difference is that the video card that will serve the additional screen is determined by the system, not the user.

Multi-display adapters

If the picture quality on the primary and secondary displays varies greatly, as well as if you need to connect not one, but 2 additional monitors to the laptop, a specialized device. a multi-display adapter will help out. It is a small box with a processor inside, reminiscent of a multiport splitter, and a few cables included. The box is connected to the output of the video card with one cable, the rest are connected to the inputs of the monitors. It receives power from a USB port or an external adapter.

An example of such a device is Matrox DualHead2Go Digital SE.

Setting up additional screens in Windows 10 & 8.1 & 7

After the first turn on, the image on the additional monitor, as a rule, duplicates the main one. Sometimes the desktop is stretched to 2 screens at once. To select the desired mode, press the WindowsP key combination (Latin). this will open the projection panel.

In Windows 10 and 8.1, it looks like this:

In Windows 7. like this:

The Duplicate (Repeating) option reproduces the same picture on all displays. “Expand”. makes the second screen a continuation of the first.

If the system could not automatically recognize the second display, open the “Display Settings” through the context menu of the desktop.

Click the “Find” button (In Windows 7. “Find”).

If the device is physically sound and correctly connected, the system will most likely recognize it immediately. If not, open the “Multiple displays” list and select “Try to connect anyway.” to a monitor that is not detected.

If this does not help, you should check the contacts and, if possible, connect the device with another known good cable to another video output or another video card.

The “Define” button in the same section allows you to select which of the two displays will be the primary (first), and which will be secondary (the second, third, etc.).

To change the settings of one of the displays of a multi-monitor system. sizes of displayed elements, brightness level, orientation, resolution, color rendition, etc., click on the rectangle with its serial number in the gray field under the heading “Customize your screen”.

Changes will take effect after saving. You do not need to restart your computer for this.

Additional multi-display configuration settings are found in the NVIDIA and AMD Catalyst Control Panel menus.

How many monitors can be connected to one computer. Connection conditions

Hardly anyone is able to name the exact number of possible connections of monitors to one PC, but 50 or more is definitely possible. It all depends on the budget that you are ready to allocate for this. To create video walls from dozens of modules, as, for example, in the photo below, special controllers are used. Their task is not only to display the image on many screens, but also to provide each picture with a decent quality.

However, video wall controllers are an extremely expensive solution that not every enterprise can afford. A more affordable option is a video server with several multi-channel video cards. But it can also cost the owner several hundred thousand rubles.

An ordinary user, like most of us, does not need such excesses. Home gaming systems, as a rule, consist of no more than six monitors, and they can be connected not just to one computer, but to one video card. But in order to achieve the highest possible image quality, it is better to distribute the monitors so that there are no more than two or three monitors per “video”.

Connecting two monitors is supported by almost any modern video card, even built into the processor (chipset). Three or more. all AMD models from Series 5 and NVIDIA GTX 600 and newer.

In addition to supporting multichannel, the following is important for creating multi-monitor configurations:

  • The presence on video cards of outputs that match the inputs of monitors (the use of adapters is allowed in extreme cases, when there is no other way to connect). over, AMD requires a mandatory DisplayPort interface on at least one of the displays (with the exception of certain branded video cards with a built-in DisplayPort-DVI adapter). NVIDIA does not set such conditions.
  • Video driver support for all monitor resolutions.
  • Sufficient video memory. 2048 Mb is a conditional minimum for a two- or three-monitor configuration in a non-gaming system. For four or more monitors, especially if you plan to use a computer for games, the memory should be at least 2 times more.
  • High data bus bandwidth (from 128 bit) and good memory speed (the more the better). The narrower the tire, the higher the speed should be.

To connect monitors to different video cards, the latter do not need to be combined into SLI or Crossfire. In some cases, in addition to the discrete card (inserted into the slot), the integrated video can be enabled if it is supported by the motherboard BIOS (there is an “Always Enable” option for the integrated video card output). But in such configurations, each pair of displays that are served by one video chip operates independently of the other. This means that creating a common visual space for all screens will not work.

If your computer is equipped with a single video card, you can connect monitors to several of its ports, or to one. To connect 2 or more screens to one video card with 1 input, you need a signal divider. a splitter. For example, as in the photo below. This modification can send a signal to 4 monitors, but the picture quality, as a rule, decreases (it depends not so much on the splitter as on the video capabilities). If the stream is barely enough for a single screen, dividing it into “streams” will reduce both the resolution and the clarity and frequency of the scan. And the more connections, the lower the quality.

When you connect the splitter to displays with different resolutions, the picture quality on them will be different: on some it is better, on others it is worse. And you cannot correct it separately, except through the settings of the monitors themselves.

AMD cards featuring Eyefinity technology (powered by ATI Radeon R800 series GPUs) allow up to 6 displays to be connected and combined into a single visual space. But here everything is tied to the DisplayPort interface, which, unfortunately, not all devices are equipped with.

The following are acceptable combinations of connection interfaces when building multi-monitor systems using AMD Eyefinity technology:

  • To combine 3 monitors into one system, one of them must be connected via DisplayPort or miniDisplayPort (miniDP), the second via DVI, and the third via VGA, HDMI or the same DVI.
  • If there are 4 monitors, two devices must be connected to DisplayPort, the third to DVI, and the fourth to VGA or HDMI.
  • In a five-monitor system, all 5 or 3 monitors are connected to DisplayPort (miniDisplayPort), one or two to DVI and one, if left, to HDMI.
  • Six-monitor configuration only allows connection via miniDisplayPort.

NVIDIA Surround / 3D Vision multi-monitor technology allows you to create a shared gaming space from three monitors. However, this requires either a dual-processor video card or the combination of two or three cards in SLI. Several more displays can be connected to the remaining video outputs, they will work independently of the rest.

If you do not have a task to build a video wall for displaying one picture on several screens, it is not necessary to adhere to the above rules. Monitors can be connected in any configurations through any interfaces at the rate of 2 devices per 1 video processor. over, each of them will display its own desktop, and you can switch between them, drag windows from one table to another, etc.

How to connect a second, third. tenth monitor to one computer

Today’s multi-monitor PC configuration is no surprise. And soon, one should expect, having a single display on the table will become an exception, not a rule. So say people who had the opportunity to compare the convenience of working at a computer with one and several monitors. And the second option, if you believe their words, is much more convenient than the first.

The statistics are of the same opinion. According to their research, if you connect 2 monitors instead of one, the productivity of personnel involved in processing a large amount of information increases by 15-60%. What can we say about gamers, for whom multi-monitor systems are the only way to go headlong into the virtual world?

How to connect and configure additional monitors in Windows

Configuring Extra Screens in Windows XP

To access the display options in Windows XP, also open the desktop context menu and click Properties. Next go to the “Options” tab.

If the second monitor is correctly recognized, 2 display icons with sequential numbers will appear in a gray field. The “Find” option, as in modern versions of Windows, is not here.

By default, both screens display the same desktop image. If you want to stretch it, click on the icon of the second display and check the box “Extend my desktop to this monitor”.

Setting up each screen individually is performed in the same way as in Windows 10: click on the monitor icon in the gray field and set the desired parameters. Options “Screen Resolution” and “Color Quality” are located here, and the rest. scale, adapter properties, etc., is hidden behind the “Advanced” button.

Most of the settings take effect immediately, but some. only after restarting the computer.

How to connect two computers to one monitor? Is it possible to connect two system units to one monitor?

In sci-fi movies, vaguely reminiscent of reality, and various pictures about hackers, the theme often flashes when one user uses several displays for different tasks. This form of communication between a person and a computer is familiar to almost everyone and is quite common in the real world. But there is also another side of the “coin”. connected one monitor to two system units. Why do this? What will it give? And most importantly, how to connect two system units to one monitor? We will consider the answers to these and other questions.

There are many server applications, it would be a fantasy.

Having set up a server at home, an ordinary user can conduct many interesting experiments, for example, with programming. It is very convenient to receive feedback from your personal server, to see the intermediate result, without thinking about connecting to the hosting. You can check the performance directly on your server; for this, special software is installed

Connect or not connect, or Modern Serpent-Gorynych

Without understanding the goals and objectives of this type of connection, it makes no sense to even think about how to figure out how to connect two computers to one monitor. And even more so to start doing something. It makes sense to connect two computers to one monitor at the same time to display graphic, text and other useful and useless information if you have a server and, of course, another computer.

We check the correctness of the connection

We carefully check: the output cable for the keyboard should stick out in the keyboard port. Input ports must contain cables from system units. And the weekend. from the monitor. and nothing else, if you do not want to repeat the whole procedure again, but, most likely, with new equipment. A couple of minutes to check will save both effort, money and time.

So, everything is ready, checked, rechecked. We connect the KVM device. Do not forget, of course, to turn on both computers in advance. And now, to move from one station to another, it is enough to double-click the NumLock button and the numbers 1 or 2. The number of the number indicates the position of the computer in the system. If the computer number, in the user’s opinion, does not correspond to the key on the keyboard, then this misunderstanding can be corrected. To set up a convenient switching for us, the KVM manufacturers took care of the software, using which it is possible and necessary to program the buttons we need for the corresponding block. So the main goal. how to connect two computers to one monitor. reached!

What is a server and what is it with??

Server is a “well-known” concept. Usually, it is thought of as a large, powerful computer that looks like a cabinet with light bulbs. And only large companies, corporations, banks, factories and other large structures use it.

In fact this is not true. In common parlance, a server is a service personnel. The service computer provides services to other machines connected to it. This collective activity offloads the computers connected to the server and increases overall labor productivity. The processing speed is also increasing, and such a useful option saves users’ nerves. There are several types of servers, each of which performs a specific type of task.

Divide and rule

Having dealt with the goals and objectives, let’s proceed to a step-by-step consideration of the question of how to connect two computers to one monitor.

There is one more side for the input signals on the KVM switch. This half of the device has ports for the first and second system units. First, we connect a keyboard, mouse and video card from one workstation to them, and then a SIMilar operation is performed for the server. Or vice versa. Changing the places of the terms does not change the sum.

The best option

We work!

Well, the answer to the question of whether it is possible to connect two computers to one monitor is given. Now it became clear how to implement this, and why such a “double” connection is needed, as well as what benefits it can bring to the average user. The proposed method is not the only one for connecting two workstations to the monitor. There are also alternative techniques. We’ve covered the KVM switch method as it’s SIMple and intuitive. And both an advanced user and a novice user can handle it.

How to connect HDMI to VGA or VGA to HDMI. What are their SIMilarities and differences.

Take VGA (Video Graphics Array) and HDMI (High Definition Multimedia Interface) as examples. Since both of these connectors are made for video transmission, it would make sense that a person should be able to connect them together by SIMply making a cable with the correct connectors on both ends. However, this theory is far from the truth. VGA and HDMI are extremely different systems that don’t even speak the same language, even though they both carry a video signal. VGA was created as a video standard for computer monitors in 1987. On the other hand, HDMI was created in 2002, making it the most relevant modern connectivity option.

So what’s the difference between VGA and HDMI? In fact, there are many differences between the two. The first and probably most important is that the VGA connector uses an analog signal, while the HDMI connector uses a digital one. The second difference between VGA and HDMI signals is that VGA is just a video signal, while HDMI carries not only video but also stereo audio audio signal. Another difference is that the VGA connector and the HDMI connector are SIMply not the same. You can’t just connect a wire from one source to another sink. The big difference between the two is the difference in resolution between VGA and HDMI. When we use the term “native resolution” we are talking about the actual number of rows and columns of pixels (color dots) that appear on the screen. Initially, the VGA was created in four different graphics modes: 640 x 480 pixels in 16 colors 640 x 350 pixels in 16 colors 320 x 200 pixels in 16 colors 320 x 200 pixels in 256 colors. Initially, the resolution was not great, but the predecessor to VGA was CGA, which had only 320 x 200 pixels. Since then many new modifications have been developed for VGA including: SVGA (Super VGA) monitor whose resolution is 800 x 600 pixels. XGA (Expanded Graphics Array) resolution which is 1024 x 768 pixels WXGA (Wide Expanded Graphics Array) resolution, which is usually 1280 x 768 or 1280 x 800 pixels, which allows widescreen monitors to be used for watching movies All of these different formats (very large quantity) are still considered part of the VGA family. They all use the same D-subminiature connector and any transmitting device with a VGA connector can connect any image display device that has a VGA connector. The HDMI connector, which is designed primarily for use with HDTVs, comes in two main flavors: 720p, which has 720 horizontal pixel lines, which makes an actual resolution of 1280 x 720, and 1080p, which has 1080 horizontal pixel lines, which makes an actual resolution of 1920 x 1080 When the monitor cannot display as many lines and pixels as it receives from the signal source, it either crops the edges of the image, or usually clips out some of the rows and columns of pixels, which allows the image to be displayed correctly. If the monitor is capable of showing more rows of pixels than what is being transmitted from the signal source, it duplicates the rows and columns of pixels, which makes the image larger. This process of changing the number of resolution lines from the input signal is called “scaling”. HDTV signal has more lines of resolution than normal VGA signal, so it needs to be scaled while converting from analog to digital.

To connect HDMI to VGA or VGA to HDMI special devices are used. converters, signal converters, which you can find on our website vgahdmi.ru. These devices contain a complex conversion circuit and contain a special chip that converts either an analog signal to digital sound, or vice versa, a digital signal to analog sound.

When do you need to use these converters? For example, we have an ordinary monitor with a VGA connector and we want to connect a device with HDMI output to it, for example: laptop, DVD player, HD camcorders, game console, satellite TV, etc. For this we need a device. converter from HDMI to VGA. Such converters come with support for sound transmission from HDMI and without sound, which only transmit the image to the receiver (monitor, projector, LCD, etc.) with vga.

Now let’s consider the next case when we need to transfer an image from VGA to HDMI signal. For example, submit an image from a computer, laptop and other devices with vga output. to a TV, monitor, LCD projector or plasma panel with HDMI input. For this we need a VGA to HDMI converter.

Conclusion: with the help of the converter we solve the communication problem between HDMI and VGA connectors and can enjoy high quality picture.

How to connect a monitor to a laptop

Modern laptops are practically not inferior in performance to full-fledged desktop computers. In this case, 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 talk about how to connect a monitor to a laptop.

To connect the monitor to your laptop first

Interfaces for connecting a monitor to a laptop

VGA is the most common interface and can be found in almost all laptops. VGA is a legacy analog interface. However, 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 paired with VGA. Also, the HDMI port can often be found on other computer equipment. For example, on tablets or smartphones.

DVI is ideal for connecting a monitor to a laptop. Currently DVI is considered the standard for connecting monitors. However, DVI is quite rare on laptops.

DisplayPort is one of the newest interfaces for displaying images. DisplayPort has been rapidly gaining popularity lately and is increasingly seen 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 both on the monitor and on 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.

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 the connection of the monitor to the 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 mode of duplicated screens. 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 the laptop and on the 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 only select one of the screens. While the second monitor won’t work. This mode is suitable if you only want to work with a connected monitor.

How to connect a laptop as a monitor

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.

Use your laptop as a monitor with a cable connection

Having decided on the necessary cable and using it to establish a 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 extend the PC desktop to the connected device by checking the box opposite the corresponding menu item. To do this, you need to confirm the changes made by clicking the “Apply” button, and then “Ok”. After completing these SIMple settings, you will be using the 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 the required cable;
  • discrepancy between laptop and stationary PC connectors;
  • the need to purchase an adapter.

How to use a laptop as a computer monitor or another 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 the power of the system unit and the data stored in it in the future, you need a monitor of another external device. The same situation can occur if the display matrix of another laptop does not work correctly.

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 setup points, 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 utility. 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 room (must be installed on the main device).

When starting the application, 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 paired 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.

Directly

  • Turn off your computer and external screen.
  • Connect the cable to the corresponding port of the laptop and monitor.
  • Include both.
  • Configure.

Step-by-step connection instructions

Using the docking station

A docking station is a special piece of equipment with ports used to connect multiple gadgets at the same time. In the case when it is necessary to work on 2-3 monitors from one laptop, they are used.

Reference. Almost all popular gadget manufacturers have a docking station in their assortment. This is due to the fact that modern laptops are getting thinner and lighter. There is no need to have absolutely all possible interfaces with you at all times, if you can get a separate docking station and use it as needed. In addition, it is a great addition to existing ports.

The connection technology is not intuitive:

  • Turn off laptop and external screen.
  • Connect the docking station to the computer via USB.
  • Connect the cable to the appropriate port on the dock and monitor.
  • Turn on both monitor and laptop.
  • Configure.

The sub screen can be customized in different ways depending on the goals. On the keyboard of laptops, there are often “hot” keys for working with the monitor. To call the menu of actions with the screen, you need to hold down the Fn key and the corresponding key with the drawn monitor or WinP. Next, there are 4 ways to project the image:

  • Computer screen only. only laptop screen is on.
  • Duplicate. external screen duplicates activities on the laptop.
  • Expand. increase the work space, both screens act as one.
  • Second screen only. the image will only be shown on the external monitor.

Through adapters

How to connect one or more monitors to a Lenovo laptop

A portable laptop provides the user with maximum mobility, while many models are not inferior in performance to a PC. Often there is a need to connect additional devices to a laptop to increase its functionality. Working with presentations, graphs, program codes, comparison tables requires “wide format”, which this gadget does not have. For this, an external screen with a higher resolution quality is used.

Varieties of ports for connecting an external monitor

  • VGA (D-Sub). suitable for SIMple projectors, office monitors, set-top boxes. To connect to modern models, adapters are used: VGA-HDMI, VGA-DVI, etc. The main advantage is its prevalence. But VGA cannot boast of a large expansion without loss of picture quality. 1920 × 1080 and higher is only capable of it with good equipment capabilities.
  • DVI is a less popular interface. There are several outwardly absolutely identical varieties: DVI-A (for analog signal), DVI-D (for digital), DVI-I (universal). The only difference is in the contacts involved. If you are very sophisticated with adapters, you can achieve image transfer to 4K monitors, but this does not guarantee high quality.
  • HDMI is a modern and convenient interface. With its help set-top boxes, monitors, TV are connected. HDMI technology allows video and audio to be transmitted with minimal loss. There are several variations: micro, mini and full size. The advantage of HDMI is its popularity and versatility. Technics with such an interface will be produced for a very long time. The disadvantages include high-quality loss of sound and image when combined with other technologies.
  • Display Port is a high bandwidth interface. It is a modern alternative to HDMI. It seamlessly supports not only 4K monitors, but also FullHD, a picture in 3D. Display Port mini meets. This interface is slightly less common than HDMI, but is gradually gaining popularity. The undoubted advantage is the high quality of technology.
  • Type C is a universal connector for data transmission, streaming, charging and more. over, if the laptop has only one Type C connector through which the laptop is charged, then when a supporting monitor is connected to this port, the laptop will not only transmit a streaming image, but also charge.

Not all laptop models support more than two monitors.

Setting up a monitor in Windows 10

On the free space of the Windows 10 desktop, right-click. In the window that opens, select the “Screen settings” item. The display setup menu appears. To switch to an external monitor, you need to click on the square with the number 2. Now it can be adjusted in the same way as the main one: change the resolution, contrast and brightness, scale, and flip the image. The “Orientation” item will help you choose how the desktop is displayed: duplicate, expand on both screens, enable only the first or only the second.

Note. Many TV monitors have their own audio system, which is often louder than a laptop. To switch, you need to right-click on the speaker image in the lower right corner of the taskbar. We select the item “Playback devices” and in the list we find the name of the external screen.

With the necessary cables, connecting your laptop to an external monitor is quick and easy. The correct operation of the equipment depends on the compatibility of the technologies. Universal docking stations keep you mobile.
