How to enable a second screen on Windows 10

Configuring Windows 10

Unlike older versions of the operating system, Windows 10 is the most convenient for working with multiple displays. There are three ways to mirror your PC screen to TV in Windows 10.

The first way is the easiest. With the computer turned on, simultaneously press the “Windows” “P” keys. This combination allows you to switch between dual-screen computer modes. It remains only to select the desired mode.

If keyboard shortcuts are confusing to the user, you can use Windows Action Center. In the lower right corner of the screen, you need to click on the corresponding icon. A window will open in which you need to select the “Send to screen” item. In the appeared menu “Project” select the item “Repeating”.

Activating Screen Mirroring in Windows 10

If the TV screen resolution is higher than the monitor screen resolution, then the picture on the TV display will be located in the center, surrounded by black borders. In this case, you need to use the following method.

On the desktop, in an unoccupied place, click the right mouse button. A context menu will open, in which you need to select the “Display settings” item. In the window that opens, find the item “multiple displays” and click on the pop-up menu. In it, select the item “Duplicate screen”. After that, be sure to select a TV (screen 2) and check the box “make the main display”.

Connecting a TV to a Computer

The first thing to start with is choosing a cable. It is required to inspect the back of the system unit and determine which free video outputs are present on it.

Then the same thing needs to be checked on the TV. It is required that the same connectors are free on the computer and on the TV. If both ports are free, then it is better to give priority in favor of the HDMI connector, since it has a higher bandwidth, and, therefore, better quality. Plus, HDMI connects not only image but also sound.

If the computer will be connected to the TV via the VGA connector, you should note that on most modern TVs, when connected via this video output, the screen resolution will be significantly lower than the “native” TV resolution, which will negatively affect the image quality. In the characteristics of the TV, the screen resolution is always separately indicated when connected via the VGA connector.

IMPORTANT!
The cable to the computer and TV should only be connected when the devices are turned off!

After the computer and the TV are connected with a cable, it remains only to indicate on the TV from which connector to receive the image (usually the source button).

Mirroring your computer screen to your TV

There are often situations when the size of the monitor is not enough for comfortable work with a computer. In this case, the computer is connected to a TV or projector and the image is displayed on it. But what if you want the picture to be displayed both on the main computer screen and on an additional TV connected to it? In this article, we will show you how to mirror a computer screen to a TV in Windows 10. To do this, you will need:

  • Computer with an unused VGA or HDMI connector
  • Cable connecting computer and TV
  • TV with the above connectors

From all of the above, we can conclude that connecting a computer to a TV is not so difficult. The main thing is to follow the instructions and everything will work out. This manual is also relevant for connecting projectors and other devices for displaying images from the computer screen.

How to enable HDMI on Windows 10

How to properly connect a laptop to a TV via HDMI?

Immediately, we note that in order to connect everything, you will need to set the desired parameters on the TV and laptop. You will also need the HDMI cable itself. Also, note that some laptop models only have a DVI connector. Then you will also have to get a special adapter.

The procedure itself for connecting a laptop to a TV via HDMI is quite simple. You need to do the following:

  • We make sure that there are connectors on both devices.
  • We turn off the TV and laptop. This is to protect the ports. If you connect the cable with the devices turned on, then there is a risk of their failure.
  • We connect one end of the cable to the HDMI connector on the TV. Typically, modern TV-devices have it on the back or side. In this case, there can be several connectors. Usually they are all signed. HDMI 1, HDMI 2, etc. In which of them you connect the cable there is no difference.
  • We connect the other end of the cable to the laptop. Now we turn on both devices and go to the connection settings.
  • We start with the TV. We pick up the remote control and press the button on it, which is responsible for setting up signal sources. This is often the key “input”, “source” (on LG, Samsung TVs, etc.) or “home” (on some Sony models).
  • A menu will appear on the TV screen (its interface is very different depending on the TV and the manufacturer!), Where you need to select the signal source. In our case, HDMI. If you choose the wrong option, the following message will appear on the TV screen: “No signal”. Do not be afraid! Just click on another signal source.
  • That’s all. Most likely, everything worked out for you, and you are already watching a movie or playing computer games using a TV monitor, and not a laptop screen.
  • If the laptop did not connect to the TV and it was not possible to display the image on its screen, then on the laptop we go to “Start”. Further in the “Control Panel”. Click on the item “Setting the screen resolution”. Next, in the “Screen” line, select the TV screen if it was not automatically recognized. Press the button “Find”. For laptops with Windows 10, go to the system settings in the “Screen” section and click on the “Detect” button.

Helpful information! Not all laptop models have an HDMI connector. In this case, some users, using an adapter, connect the device via VGA. This is a fairly old 15-pin connector that became popular back in the 80s of the last century. However, no sound is transmitted through such an interface. Therefore, in addition to the HDMI cable, you will need to connect an additional wire for the audio signal.

Problems when connecting a laptop to a TV using an HDMI cable are far from uncommon. Therefore, we will dwell on this point in detail. we will describe the most common problems and ways to solve them.

enable, second, screen, windows
  • What if you connected everything correctly, but the TV screen does not show the image from the laptop? The first thing we do is sit down at the laptop. Right-click on the desktop. In the menu that appears, select the line “Screen resolution” (for Windows 7, 8). Now you need to select “Multiple monitors” in the “Screen” item. Below you will see another option “Multiple screens”. Here we put “Duplicate desktop on the first and second”.
  • Why is there no sound on the TV? As we noted above, an HDMI cable carries an audio signal. So it is weird if the sound continues to come from the laptop and not from the TV device? How to fix it? Go to the notification panel and click on the sound icon. We select “Playback devices” or “Sound devices”. it all depends on the OS version (Windows 7, 8, 10, etc.). The list that opens should also include the TV to which you connected the laptop via HDMI. Click on it with the right mouse button, and then select “Use as default” or “Enable”. It remains only to click “Ok”. The sound should appear.

Sometimes there are conflicts that prevent the laptop from connecting to the TV via HDMI. The main reason is outdated or incorrectly working drivers. For example, video cards. Therefore, if you cannot connect the device to the TV, then update the software for the video adapter.

On a note! Connecting a laptop to an old TV via HDMI is hardly possible. Mainly due to the lack of an appropriate interface. Therefore, if you have a rather “ancient” TV receiver, then you can connect it to a laptop only through RCA (everyone knows them as “tulips”).

HDMI setup

After Windows boots up, select the appropriate screen resolution. To do this, right-click on an empty space on your desktop and then select the appropriate “Screen Resolution”.

Here you can choose the appropriate resolution. A higher resolution produces a sharper picture, but everything on the screen will be smaller. The system defaults to the maximum resolution supported by the device. If everything suits you, don’t change anything. If you are not comfortable working with such a resolution: the font is too small and difficult to read, you can reduce the resolution, taking into account some of the nuances. Some monitors and TVs are designed to show a strictly defined number of pixels vertically as well as horizontally. If you set a non-standard resolution, your TV will have to scale it to display it on its matrix, which can lead to blurring of the picture and deterioration of the image quality.

If your TV supports Full HD resolution (1920 × 1080), it will reproduce 1280 × 720 just as well, but all fonts and details will be larger. The real resolution of the HD Ready TV is 1366 × 768, it makes no sense to set the resolution to 1920 × 1080.

FIX: Windows 10 Not Detecting Second Monitor [Quick Tutorial]

On the monitor tab, located in the “Advanced settings”, you can set the required refresh rate of the screen. You can set it to 60 Hz or more (if your TV supports it):

If the video is not running smoothly enough or jitters during playback, you can experiment with this parameter by changing its value. Set the color quality to “True Color (32-bit)”.

Whenever you change the resolution, color depth or frequency, a window appears in which you need to confirm the changes. If your device does not work with the new parameters, you will not be able to see this window and confirm your actions. Don’t worry, fifteen seconds later, your computer device’s system settings will be restored to their previous system settings.

What is important to know about HDMI?

Recently, HDMI data transmission technology has become very popular. Largely due to the fact that with its help it is possible to broadcast a video and audio signal of a sufficiently high quality. This uses only one cable.

There are currently several HDMI standards:

  • 1.0 standard (speed up to 10.2 Gbps, support for up to 8 audio channels);
  • standard 2.0 (data transfer at speeds up to 18 Gbps, as well as support for up to 32 audio channels).

Many companies are involved in the production of HDMI cables. Branded options are often quite expensive. However, many modern TVs have such a cable included.

How to connect a computer or laptop to a TV via HDMI?

Many people who have a large plasma or LCD TV at some point think about connecting it to their computer or laptop. The opportunity to watch a movie on a large screen is of great interest to many users. First, let’s get acquainted with the possible ways of connecting these devices, then we will understand the settings of the video card, and at the end we will consider how you can output sound via HDMI. For the simplest connection of the above devices, you only need to have an HDMI cable with the same connectors at the ends. Any, even the most inexpensive cable is suitable, but note that if you are going to use 3D mode, the version of the cable must be HDMI 1.4 or higher. Find the HDMI jack on your computer case, as well as on the back of your TV. This is how this socket looks on the back of the TV: And this is an image of the socket on the side wall: But such a socket should be looked for on the back of the computer’s system unit: This socket is located directly on the video card, next to the connector for connecting a DVI or VGA monitor. If a discrete video card is not installed in your system unit, the socket will be located on the motherboard, near the USB ports. With laptops it is lighter, the HDMI socket in them always looks the same, just in different models it can be on different sides: In portable computer devices (tablets, netbooks, cameras, etc.) install mini-HDMI connectors, which are three times smaller than a conventional connector, so they need a mini-HDMI cable.

Many modern users have an LCD TV hanging on the wall, which makes it difficult to connect a massive cable to its back surface.

For such cases, cables are provided with the plug at right angles. You can also, if you wish, purchase a special HDMI corner: With this corner, you can connect to the TV from the back or from the side. Some adapters even support the ability to adjust the angle and the bend in them is not straight, but in any direction. Before buying, decide in which direction the cable will come out after connecting it through the corner. Please note that different cable models are oriented in different directions.

You will not be able to connect without HDMI connectors (however, if you have a DVI monitor connector, you can use a DVI-HDMI adapter).

How to set up a second monitor in Windows 10

This guide shows the steps you can take to set up a second monitor in Windows 10.

Windows 10 operating system by default supports multi-monitor systems of various configurations and therefore you do not need to install third-party software to set up multiple displays.

The need to use a second monitor is needed primarily to expand the workspace, which in some cases simplifies the simultaneous execution of several tasks.

It is important to note that some video cards do not support multiple monitors, and that older displays may not always connect automatically.

Further, the article describes the settings of various parameters when connecting a second monitor to a computer.

To connect a second monitor, you need a computer (laptop) or a video card with an additional video signal output to an external display using various connectors, such as HDMI, VGA, DVI port or DisplayPort, as well as an appropriate cable that connects the monitor to the connector (port).

Configuring display options

Setting up and managing displays using Windows is very simple, to do this, open one by one: Windows Settings ➯ System ➯ Display, or right-click in an empty area of ​​the desktop and select Display Settings in the context menu that appears.

Select the background for the second monitor in the same way.

You can also choose the position of the wallpaper from the Select a position drop-down list.

Reasons why the problem occurs

Windows ten may not see another monitor connected to a stationary computer or laptop for the following reasons:

  • Incorrect connection. The user can make a mistake when performing the task, for example, by plugging the VGA cable into the port on the motherboard, not into the connector on the video card. The same goes for using the DisplayPort connector.
  • Incorrect computer settings. After connecting the additional screen, the user must perform the initial setting of the parameters. If he does not, then the device will not be identified.
  • Problems with the connection interface, connectors. For example, the VGA, DVI or HDMI cables used to connect are damaged, frayed, or inoperable. In this situation, the wires will need to be replaced.
  • Viral infection of the PC. As one of the reasons for this problem. If the user is unable to synchronize the PC and the second display with each other, then, first of all, it is recommended to check the computer for malicious software.
  • The lack of a driver for the video adapter. Many PC users face this problem. It can be solved in the shortest possible time by downloading the latest driver from the official website of the video card manufacturer and installing it.

Note! The problem can also be caused by damaged connectors on the video card or its physical condition, for example, overheating.

What to do if HDMI and DisplayPort Problems began to appear

Almost all modern video cards are equipped with these connectors. These ports are designed to output a digital signal, that is, an image to a monitor. If there is no image on the second display connected to the PC, then the user is advised to do the following:

  • Move the HDMI cable to the adjacent connector on the video card. The video adapter has multiple HDMI ports. Therefore, the cable can be easily rearranged into another connector and check if there is a picture on the screen. Perhaps one of the ports went out, which was the reason for the absence of an image on the monitor.
  • Do the same with DisplayPort.
  • Disable the use of the connector integrated into the motherboard in BIOS. This circumstance is relevant if there is no picture, both on the first and on the second monitor. It is possible that only integrated graphics are set in the BIOS and the ports of the video card are disabled, not used.
  • Inspect HDMI and DisplayPort connectors. If they show chips and scratches, then such ports are most likely inoperative.

Important! If the above manipulations did not lead to a positive result, then it is worth trying another method of solving the problem.

Reinstalling the driver on the video adapter

Often the Windows 7 operating system does not see the second monitor due to an outdated video driver. To solve the problem, it is recommended to use the following algorithm:

  • Go to the official website of the manufacturer of your adapter. For example, Nvidia or AMD.
  • Go to the section responsible for software downloads.
  • Select your adapter model from the list provided and the version of the operating system.
  • Download the latest driver.
  • Install the software following the installer prompts.
  • Restart the PC and check if the image appears on the secondary screen.

Note! During the driver update process, the image on the main monitor may disappear for a few seconds. Do not be afraid of this, tk. the picture will be restored in the near future.

Why Windows 10 does not see the second monitor. ways to fix the problem

Many users connect two monitors to one computer. However, certain problems may arise with the synchronization of these devices. This article will explain why the Windows 10 operating system does not see the second monitor.

Display 2 not active Windows 10 due to VGA issues

Old-style VGA connector, which is now practically not used either on video cards or on motherboards. However, it can also connect two monitors to one computer. If the video card has only VGA connectors, but at the same time these ports are absent on the monitor, then you should use an adapter, for example, from HDMI to VGA.

If the picture on an additional monitor connected to the VGA connector cannot be displayed, then the user is recommended to do the following:

  • Carefully inspect the port on the cable and on the video card for integrity. If no external damage was found during inspection, then it is worth first checking the cable on another computer, and then the video card. A similar result indicates problems with the VGA connector, or with the video adapter itself.
  • Connect the monitor to the adjacent connector. If there is still no picture on the screen, then the problem is in the video card. In this case, the image should be absent on both displays.
  • Take a close look at the VGA to HDMI adapter. Sometimes you can cope with the problem of the absence of an image on the secondary screen by moving the adapter. It may be coming off the cable or connector.

Additional Information! Previously, VGA to DVI adapters were bundled with Nvidia video cards. Now it will need to be bought separately.

On Windows 10, the monitor is not detected due to problems with the converter

As mentioned above, the convector is an adapter from one connector to another. It is needed in cases where the video card does not have a corresponding port for connecting a monitor.

If a user who decides to duplicate the signal from the video card to an additional screen using a converter cannot see the picture on this monitor, then, first of all, it is worth checking the adapter for operability. To do this, you need to insert the signal conversion device into another computer, TV or connect to the adjacent connector to make sure there is an image.

If the user is one hundred percent sure that there is no image on the display due to the adapter, then the device should be replaced, returned under warranty, etc. Most likely, such a converter is not functional.

What to do if Windows 10 won’t detect the second screen

The problem due to which the display does not want to turn on can occur regardless of the version of the operating system. There are several ways to eliminate it, which will be discussed below. Each method requires an individual approach and detailed consideration.
