How to set up a screen extension on windows 10. Changing the screen resolution on Windows. Uninstalling AMD Drivers

During the development of Windows 10, Microsoft has changed the familiar display options interface. It became simpler, which allowed users to make various settings on an intuitive level. The determination of the optimal screen parameters occurs already during the installation of the system in automatic mode. It remains only to configure them for a specific user, if such a need arises. The set parameters must correspond to the maximum capabilities of the display screen and video adapter. This achieves the most accurate rendering of graphics and colors.

Screen resolution setting

Setting up the screen on a personal computer, tablet or laptop with Windows 10 is not a big problem for any user. Its interface is simple and intuitive, which allows you to modify the screen as you wish in a few clicks. To make a setting:

Click on the "Settings" icon. From the Start menu, click on the Settings icon
Click on the "System" icon in the "Settings" window.
In the "Settings" window, click on the "System" icon
Open the Display tab.
View your screen options
Check your screen resolution. It must match the recommended resolution of the device.
If the resolution is set correctly, then click on the "Graphics Adapter Properties" button.
Click on the "Graphics Adapter Properties" button
Make sure that your adapter is selected in the "Adapter Type" tab. Check if the video adapter is installed correctly
Close the Graphics Adapter Properties by clicking the OK button.
Change the screen resolution if necessary.
Close the System Options window.
Screen setup is complete.

Other screen parameters can be configured as needed.

When installing Windows 10, all screen settings are usually configured automatically. The exception is rare or obsolete types of video adapters whose drivers are not in the database on Microsoft servers. In this case, the driver is downloaded from the manufacturer's website or installed from the optical disc that comes with the computer or laptop when it is sold. It contains distributions of all drivers for installed devices.

Increase or decrease screen brightness and contrast

Brightness and contrast are among the main screen settings. Each user adjusts them individually to his own requirements.

Contrast on laptops and tablets adjusts automatically. Personal computer monitors and displays have a Menu button that allows you to adjust the contrast using the device menu.

There are several options for changing the screen brightness settings that you can apply.

Changing screen brightness in system settings

There are two ways to access screen options:

Changing screen brightness using the keyboard

Almost all modern types of keyboards have the ability to change the screen brightness without resorting to system settings. Previously, only laptops had this feature, but now this feature is also inherent in many types of personal computer keyboards. As a rule, you can change the brightness using two keys, which are marked with a sun icon and an arrow, indicating an increase or decrease in brightness. They are most often found in the upper or lower case of the keyboard.

Adjust the brightness level of your screen with the keys

In some cases, to change the screen brightness, you need to press the Fn key along with these keys.

If the keys do not respond to commands to change the brightness, download and install the keyboard driver from the manufacturer's website.

Change the screen brightness through the "Notification Center"

In the "Notification Center" you can set the screen brightness level only in fixed positions. To change the brightness level, follow these steps:

Changing screen brightness using the battery indicator on the "Taskbar"

Laptops and tablets have a battery indicator on the Taskbar, which can also be used to change the brightness of the screen:

Click the left mouse button on the battery charge indicator.
Click on the battery indicator
Click on the screen brightness tile.
Adjust the screen brightness level
You can change the brightness level by fixed values from 0 to 100% in 25% steps.
Click on the "Power and sleep settings" tab.
Click on the "Power and sleep settings" tab
Click on the line "Advanced power settings" in the right side of the opened "Settings" window.
Click on the "Advanced Power Options" tab

Changing Screen Brightness Through the Start Menu

You can also use the Start key to navigate to the screen brightness settings panel. To do this, do the following:

What to do if the screen blinks

Frequent screen blinking in Windows 10 can be caused by two problems:

using outdated video adapter drivers;
incompatibility of the software application installed on the computer and system requirements.

The problem is not as common as it was when Windows 10 just started rolling out.

This is due to the fact that the main companies that produce components for computers have brought their software applications to the required parameters. On those computers where video adapters manufactured 6–7 years ago are installed, incompatibility may occur, since their drivers were developed without taking into account modern requirements.

To fix the error, you need to find out if the driver or software application is the source that creates the screen blinking. To solve the problem and restore the normal operation of the screen and video adapter, you must use the following method:

Right-click on the "Taskbar".
Click on the "Task Manager" line. In the menu, click on the line "Task Manager"
Check for blinking in the Task Manager panel. If the panel blinks along with the screen, then the reason is the old video adapter driver. If this does not happen, then the reason is in one of the installed software applications.
Check for a Blinking Task Manager Panel
Double click on the Control Panel icon on the Desktop.
On the Desktop, double-click on the Control Panel icon
Click the Administrative Tools icon in the All Control Panel Items window.
Click on the "Administration" icon
Double-click Computer Management in the Administrative Tools window.
Double click on "Computer Management"
Expand the Event Viewer tab in the Computer Management window.
Expand the Event Viewer tab
Expand the Windows Logs tab.
Expand the "Windows Logs" directory
Check the Application and System tabs for errors.
If a software application compatibility error is found in the Application tab, then delete it. Then download the latest version of the application from the developer's website and install it on your hard drive.
Click on the "Application" tab and check for errors
If an error in the System tab indicates that an updated video adapter driver is needed, then follow the same steps for the replacement as you would for the software application.
Click on the "System" tab and check for errors

What to do if applications or games do not open in full screen

All modern programs automatically adjust to the screen size. If you install an application or game that was developed many years ago for older editions of Windows, then they can unfold in a reduced size. In this case, it becomes necessary to expand them to full screen. There are several ways to solve this problem:

Using hotkeys:
- press the Alt and Enter keys on your keyboard at the same time;
- the application will expand to full screen;
- when you press the keys again, the application will return to its previous state.
Change launch options:
- right-click on the icon of the game or application on the "Desktop";
- select "Properties" in the drop-down menu; In the drop-down menu, select the line "Properties"
- in the panel that opens, click on the "Compatibility" tab; Click on the "Compatibility" tab
- press the "Run the Compatibility Troubleshooter" button;
  Click on the "Run the Compatibility Troubleshooter" button
- if the application does not expand to full screen, then check the box "Compatibility mode" and select the required edition of Windows from the drop-down list. Keep in mind that the Windows 10 edition is not listed. The last one on the list will be Windows 8.
  
  Select the edition of Windows you need
- click the OK button.
Update video adapter drivers:
- determine the model of the video adapter in the "Device Manager";
- go to the manufacturer's website;
- download and install the new driver.
Changing the graphic settings of the game:
- start the game;
- enter settings;
- find the item for changing screen settings;
- set the full screen mode;
- restart your computer.
Screen resolution change:

If a game or application requires a screen resolution of 640X480, then you can set it in the "Parameters" block on the "Compatibility" tab. But it must be a very old game or application that was created during the appearance of Windows in the software market.

One of the main criteria for a graphical interface is brightness, contrast and color gamut. The more clearly the display of graphic objects looks, the more comfortable the work for the user will be. Therefore, do not neglect spending a few minutes in order to achieve the maximum effect when displaying graphics and text documents on the screen. It should be remembered that incorrect screen settings also affect the user's visual apparatus and may lead to a gradual deterioration of vision. You can use the methods in this article to adjust the screen and fix minor problems with the image. If they do not lead to the desired result, then you should contact the specialists of the service center.

Resolution change

The number and density of pixels involved in displaying the image depends on the screen resolution. Each monitor model has its own recommended resolution value, you can find it in the instructions for the monitor or by sorting through all the resolutions offered by the system:

Video: How to change screen resolution in Windows 10

Change orientation, scale, add multiple monitors

By going to the screen settings (the first step of the previous subparagraph), you can change not only the resolution, but also the scale, so that all fonts and icons will become either larger or smaller.

Adjust screen scale

The orientation immediately changes from landscape to portrait or portrait and vice versa. This feature is only useful if you have a monitor with a non-standard aspect ratio, such as being stretched high instead of wide.

Choose the right orientation

If several monitors are connected to the computer, then each of them will be configured separately. But first they must be recognized by clicking on the "Detect" button. Once the search is complete, the settings for each monitor will become available.

Click the "Detect" button to recognize the new screen

Troubleshooting Your Monitor

If you encounter problems while setting up or using the monitor, you should try to fix them yourself.

Blinking screen

If the screen starts flickering only in a certain application or game, this means that the program is incompatible with your build and the problem is in it. If the monitor blinks constantly, then there can be two reasons: a problem with the cable or drivers.

First, check that the cable connecting the monitor and the computer unit is not pinched or loose. Usually this is a VGA or HDMI cable. Unplug it from both connectors, plug it back in and check if the problem is gone. If possible, test the monitor with a different cable.

Check if the unit and monitor are well connected

Secondly, if you are convinced that the problem is not in the cable, update the drivers:

Games won't open in full screen

Some games may open in a window instead of full screen by default. If you want to fix this, there are two ways. The first is to use the Alt + Enter combination, which gives the command to stretch the active window to full screen, the second is to go to the settings of the game itself and set the value to "Open in full screen mode". Usually the second method works completely, the game either immediately opens to full screen, or does it after restarting.

Turn on full screen mode in the game settings

Screen calibration

Users of a Windows 10 tablet or digital pen may experience that the system does not respond correctly to finger or pen touches. In this case, you need to resort to screen calibration:

Deactivate sleep mode and turn off the monitor

By default, if the user does not interact within 15 minutes, the computer turns off the monitor. After another 15 minutes of inactivity, the system goes to sleep. This is necessary to save energy. But the power saving function can be deactivated or configured:

So, a computer monitor can be customized by changing its extension, format, brightness, contrast, and scale. If the screen is having problems, it's worth updating the drivers, checking the cable, or calibrating. You can also configure or disable computer sleep mode.

This guide walks you through the steps to change the screen resolution in Windows 10, and provides solutions to possible resolution-related issues such as resolution not available, picture looking blurry or small, and so on. There is also a video in which the whole process is shown clearly. Before talking directly about changing the resolution, I will write a few things that may be useful for novice users. It may also be useful: , .The resolution of the monitor screen determines the number of dots horizontally and vertically in the image. At higher resolutions, the image tends to look smaller. For modern LCD monitors, in order to avoid visible “defects” in the picture, you should set a resolution equal to the physical resolution of the screen (which can be found from its technical characteristics).

Changing screen resolution in Windows 10 settings

The first and easiest way to change the resolution is to enter the new Windows 10 settings interface in the "Screen" section. The fastest way to do this is to right-click on the desktop and select the "Display Options" menu item.

After that, at the bottom, click on the "Advanced screen settings" item and you will see the option to change the resolution. If you have multiple monitors, then by selecting the appropriate monitor you can set its own resolution for it.

How to Install Windows 10 on Mac

When finished, click "Apply" - the resolution will change, you will see how the picture on the monitor has changed and you can either save the changes or cancel them. If the image from the screen has disappeared (black screen, no signal), do not press anything, if there is no action on your part, the previous resolution settings will return within 15 seconds.

Using the control panel

The screen resolution can also be changed in the control panel in the more familiar "old" display options interface.

To do this, go to the control panel (view: icons) and select "Screen" (or type "Screen" in the search field - at the time of this writing, it gives the control panel item, not the Windows 10 settings).

Download Windows 10 ISO image from Microsoft website / 4 options

In the list on the left, select "Screen resolution settings" and specify the desired resolution for one or more monitors. When you click "Apply", you, as in the previous method, can either confirm or cancel the changes (or wait, and they will be canceled themselves).

Video instruction

First, a video that demonstrates how to change the screen resolution of Windows 10 in various ways, and below you will find solutions to common problems that may occur during this procedure.

Problems when choosing a resolution

Windows 10 has built-in support for 4K and 8K resolutions, and by default, the system chooses the optimal resolution for your screen (corresponding to its characteristics). However, for some types of connections and for some monitors, automatic detection may not work, and you may not see what you need in the list of available resolutions.

Screen resolution directly depends on the diagonal of the monitor (physical characteristics). It determines the number of dots (pixels) horizontally and vertically, as well as their ratio. The higher the resolution, the smaller the image on the screen and vice versa. For widescreen monitors, you should choose one resolution, for "square" - another.

If it was initially set incorrectly, then the picture quality will be noticeably lower. These may be defects such as:

black stripes on the sides;
disproportionately "sliding to the side" image;
blurry, fuzzy picture (especially visible on the text);
too large or, conversely, small icons, etc.

To prevent this from happening, the resolution must be set based on the technical characteristics of the device. You can learn it from the instructions or look at the official website of the manufacturer. As a rule, after downloading the latest drivers for the graphics adapter (video card), the computer will set the recommended settings on its own. If this does not happen, then the user will have to do it manually. The article will address the question of how to find out the screen resolution on Windows 10.

This parameter can be determined in several ways. The simplest and fastest - through the desktop. For this:

Right-click on an empty area (wallpaper) on your desktop. In the context menu that appears, select Display Options.

A new window will open with the current display settings. Here you specify the resolution, scale, orientation (landscape, portrait, portrait format) of the monitor. If other screens are connected to the PC, they will be displayed in this menu. As for the main one, you can specify the desired parameters for them, turn them over.

There is another way to access this menu. It is convenient to use it if you have a laptop, and the key responsible for calling the context menu (via the right mouse button) does not work on the touchpad. For this:

Call "Start" and in the list that appears, start typing "Settings". Choose a classic app from the Best Match category. Or just click on the gear icon.

Windows Settings will open. Find and click on the "System" category. She will be first on the list.

By default, you will immediately be taken to the screen with the desired settings. If this does not happen, then from the list on the left side of the window, click on the inscription "Display" so that the resolution is displayed on the right side.

Or, on the main Windows Settings page, immediately start typing the keyword "Display" in the empty field to start the search automatically. From the options provided, select "Change display settings".

The correct extension for the monitor will be marked with the words "Recommended" next to the digital designation. It is detected automatically if there are drivers for the video adapter.

If any other is selected, then it must be changed to the one recommended by the system. If none of the parameters has such an inscription, then this indicates the absence of drivers for the video adapter. In this case, you need to download them.

How to change

You can change the value to the desired one through the display parameters. You can get into them by following the instructions described above. Or you can use another method:

Launch the Run system utility. It can be found through the Start menu or called by the Win + R key combination on the keyboard.

In the opened window, enter the command "desk.cpl" and click "OK" to bring up the display settings.

The display options will open. Change the resolution through the appropriate category. To do this, click on the digital designation (which is currently set) and select the desired parameter from the drop-down list.

Similar actions can be done if you scroll down the page and click on the inscription "Properties of the graphics adapter".

A small window will appear in which you need to select the “Adapter” tab, and then click on the “List of all modes” button.

All extensions available for the monitor are displayed here. And even those that are not available through the "Display" menu (for example, 1920x1080 Full HD). This is handy if you want to set a non-standard setting. Select the one you want, and then click the "OK" button.

Confirm your actions to save your changes.

Please note that in the properties of the graphics adapter, there will be no corresponding inscription opposite the recommended setting. Therefore, to check if the selected option is suitable for your computer, try switching to each one in turn. If you choose the right one, you will immediately notice improvements in image quality.

Possible problems

By default, OS Windows (x32 Bit and x64 Bit) automatically determines the optimal screen settings. In some cases, this does not happen, and when you try to specify the desired extension manually, it is simply not in the list of available ones.

Most often this happens due to the lack of drivers for the graphics adapter or monitor (especially for non-standard devices). You can update them directly by downloading from the official website of the developer, or through special software.

Other reasons:

If you are sure that the latest version of drivers is installed on the PC, then try installing the required extension through the graphics adapter properties (mode selection). The method is described above and is characterized by the presence of a wider selection of available resolutions.

If you are using a non-standard monitor (applies to desktop PCs), then make sure that the drivers for it are also loaded (not to be confused with drivers for a video card). Some monitors require additional software to function properly. It can be downloaded from the official website of the manufacturer.

The problem with choosing a resolution may arise when using low-quality adapters, adapters, cables. Even if you use a laptop and connect an additional monitor to it via HDMI. In this case, try connecting the screen with another method.

Sometimes the reason for a poor image on the screen is that the diagonal of the monitor (physical characteristic) does not match the screen resolution. In that case, try:

Go to screen settings. To do this, open start and start typing "Display" in the search field. From the list of found ones, select and run "Change display settings".

In the window that opens, find the "Scale" item and check if the recommended parameters are set. If not, then return them to default.

If the recommended settings do not suit you and the image is too small at the optimal resolution, then increase its size by selecting a different value. For example, zoom in from 100% to 125%.

For finer settings, click on the inscription: "Custom scaling". Here, specify the desired parameter (the maximum of the available ones is 500%) and save the changes made. To do this, click "Apply".

In some cases, this helps eliminate a number of annoyances associated with poor image quality. Optionally, you can try to select a different screen resolution, adjust the scale. To solve other problems, most often it is enough just to download the latest drivers for the video card.

How to find out the model of the video card

To download drivers for the graphics adapter, you need to know the model of the video card. Without this information, downloading them manually will not work, because automatic online device detection does not always do this accurately.

This can be done through the special utility dxdiag. To run it:

Open "Start" and enter the name of the application. Then click on the found option.

The DirectX Diagnostic Tools window appears. Here, go to the "Display" tab. In the "Device" block, the name of the video card will be indicated. In our case, this is the Nvidia GeForce GT 220M. Copy its name to find drivers. The block opposite will contain additional information about the version of the current software, the date of the last update.

If dxdiag does not start or other problems occur in the process, then you can find out the model of the video card in another way using standard tools from Microsoft. For this:

Open "Settings" and go to the display settings (the method is described in the instructions above). Here, find the inscription "Properties of the graphics adapter" and click on it.

Click the "Adapter" tab. The "Type" and "Details" blocks will contain information about the video card model.

Knowing the name of the graphics adapter, you can download the driver from the manufacturer's official website. After that, you can set the optimal screen resolution on Windows.

How to download drivers

Once you know your graphics card model, you can easily download and install the new software version manually. For this:

In the search engine, enter the name of the video card manufacturer (for example, Nvidia) + drivers. Then go to the official site. To do this, click on the first suggested link from the search results.

The browser will redirect you to the "Drivers" tab, but if this does not happen, then go to it yourself from the main page. Here, specify the type, series and product family, following the information received earlier and the OS version. Click on the big green "Search" button.

Agree to the license terms and click Download. The software download will begin. Wait for it to complete, then run the installation file and follow the instructions of the Windows wizard.

The screen resolution will automatically change to the optimal one. If this does not happen, then follow these steps yourself. Through the display options.

How to update drivers

You can find out the model of the video card and immediately update the drivers for it through the standard features of Microsoft Windows as follows:

In the Start menu, start typing "Control Panel", and then launch the found desktop application.

For a more comfortable experience, change the way you view available options to large or small icons. Then find "Device Manager" in the list. Click on the inscription with the left mouse button to launch the application.

In the window that opens, find the category "Display Adapters". Please note that there may be several subcategories available here, depending on the features of your computer. If any drivers were installed for the device, then there should be a model name (in our case, this is Nvidia GeForce GT 220M). If they are not available, then you will see the inscription "Unidentified device".

Specify the path to the files. To do this, click the "Browse" button and select the folder with the downloaded drivers. Click "Next" to start the installation.

After the process is completed, the most optimal for your screen will appear in the list of available resolutions. Remember that next to it there will be a corresponding inscription "Recommended".

If you are already using the latest drivers, the system will display a message that the most appropriate drivers are already installed on this PC. Such a notification may also indicate that Windows could not find updates. In this case, you can try to download them manually, through the official website (the method is described above).

Conclusion

You can find out the screen resolution through the display settings or by right-clicking on the desktop. After that, you can see the current value, and optionally change it to the required one. Please note that it must match the technical parameters of the monitor (diagonal).

If these characteristics do not converge, then the image quality will be noticeably lower. If the required screen resolution is not available, then most likely you will need to update the drivers for the graphics adapter. You can do this using the built-in Windows tools.
