Screen flashes black: Troubleshoot screen flickering in Windows

Troubleshoot screen flickering in Windows

Screen flickering in Windows 11 is usually caused by a display driver issue or incompatible app. To determine whether a display driver or app is causing the problem, check to see if Task Manager flickers. Then, based on that information, you’ll need to update, rollback, or uninstall your display driver or update or uninstall the app.

For more, select any of the following headings, and it’ll open to show more info:

Press Ctrl + Alt + Delete to open Task Manager. If you don’t see Task Manager after pressing Ctrl + Alt + Delete, press Ctrl + Shift + Esc to open Task Manager.

If Task Manager flickers along with everything else on the screen, a display driver is probably causing the problem. In this scenario, see the Fix your display driver section.

If Task Manager doesn’t flicker while the rest of the screen is flickering, an incompatible app is probably causing the problem. In this scenario, see the Update or uninstall an incompatible app section.

  How to Fix Screen Flickering and Flashing on Windows 10 and 11
  
  If your Windows 10 or Windows 11 screen is constantly flickering, it’s likely because you have a troublesome application installed or an unsuitable display driver. It’s time for you to resolve that annoying screen flash.
  
  The problem often begins when upgrading to Windows 10/11 from a previous version of the operating system, but it can occur at any time. We’re going to show you various methods to fix a Windows 10 or Windows 11 flashing screen.
  
  Perform This Screen Flickering Test First
  
  First, you need to establish what might be causing the flickering screen. To do this, open Task Manager by pressing Ctrl + Shift + Esc simultaneously.
  
  Alternatively, on Windows 10 you can right-click your taskbar and select Task Manager. You don’t actually need to use Task Manager, but you do need it open.
  
  Now, watch your screen to see if Task Manager flickers. If it does, along with everything else on the screen, the problem is likely caused by your hardware or a faulty display driver. On the other hand, if everything except Task Manager flickers, the issue is likely due to an application.
  
  If it’s the former, follow the instructions below in order. If it’s the latter, skip to step five. That said, if the advice there doesn’t work, check the advice in the other sections too.
  
  1. Check Your Monitor and Cables
  
  If you have a flashing screen, the first thing to rule out is the hardware. Check all the cable connections from the monitor to the computer—take them out and plug them back in to ensure the cables are secure.
  
  If you have a spare monitor cable, try using it instead. Or buy a replacement online, since it’s an inexpensive purchase. Cables can degrade over time, or maybe a pet has had a sneaky chew. Either way, switch the cable and see if it stops screen flickering.
  
  If you can, try a different monitor. If this resolves the problem, you know it’s your monitor that’s the issue. At that point, contact the manufacturer for support or to raise a warranty claim.
  
  2. Set the Correct Refresh Rate
  
  A monitor’s refresh rate is the speed at which the screen updates the image per second, measured in hertz (Hz). Basic monitors can usually only handle a 60Hz refresh rate, while more advanced ones—typically aimed at gamers—can go up to 360Hz.
  
  It’s important that you set a suitable refresh rate for your monitor. Sometimes a monitor manufacturer will support an overclocked refresh rate, but this can cause screen flickering.
  
  To adjust your refresh rate:
  1. Press Windows key + I to open Settings.
  2. Click System > Display.
  3. Click Advanced display settings (Windows 10) or Advanced display (Windows 11).
  4. Use the Refresh rate dropdown and incrementally select lower rates until the screen flashing stops. If the flashing continues, revert to your monitor’s recommended refresh rate.
  3. Reset Your Display Driver
  
  The screen flashing could be caused by your display driver. You might have an old driver or a faulty new one. Let’s make sure you are running the right version for your system.
  
  Remove the Driver
  
  First, boot Windows in safe mode:
  1. Press Windows key + I to open Settings.
  2. Select Update & Security > Recovery (Windows 10) or System > Recovery (Windows 11).
  3. Underneath Advanced start-up, click Restart now.
  4. When your system restarts, select Troubleshoot > Advanced options > Startup settings > Restart.
  5. Again, once restarted, select option five to launch your PC into Safe Mode with Networking.
  Next, use Device Manager to uninstall the display driver:
  1. Press Windows key + X and click Device Manager.
  2. Double-click on Display adaptors to expand the category.
  3. Right-click your graphics card, click Uninstall device, check Delete the driver software for this device and then click OK.
  4. Restart your system again.
  Alternatively, you can use third-party software Display Driver Uninstaller, which will completely wipe any traces of the driver from your system.
  
  Install a New Driver
  
  You now want to install the latest driver for your system. Windows Update will provide the driver it thinks is compatible with your system. To do this:
  1. Press Windows Key + I to open Settings.
  2. Click Update & Security (Windows 10) or Windows Update (Windows 11).
  3. Click Check for updates.
  Alternatively, you can go to your graphics card manufacturer’s website (likely AMD, Nvidia, or Intel) and manually download the driver from there.
  
  Download the driver, install it, and see if the screen flashing problem has ceased.
  
  Roll Back to an Older Driver
  
  If the problem continues, it might be that the newest driver hasn’t patched the problem. If the screen flickering occurred after a driver update, try rolling back to an older version.
  
  Follow the steps above to uninstall the driver, then head to the old driver page for either AMD, NVIDIA, or Intel. This might be a bit of trial and error, but try selecting one released when your screen wasn’t flickering.
  
  4. Reseat Your Graphics Card
  
  If the problem isn’t with your display driver, it doesn’t mean your graphics card isn’t to blame. If your graphics card isn’t seated correctly in your motherboard, it can cause your monitor display to flicker on and off.
  
  You can easily check this if your motherboard has inbuilt graphics. Remove the monitor cable from your graphics card and plug it into the motherboard’s display slot instead. If the flashing stops, you know the graphics card is the problem.
  
  Power off your PC, unplug everything, open the case, and remove your graphics card from the motherboard. Then carefully reseat it, ensuring the card firmly clips into the motherboard. Of course, don’t do this if you’re not comfortable working inside a computer because you might make things worse.
  
  If this doesn’t fix it, your graphics card might be faulty. Contact the manufacturer for support or to claim on the warranty.
  
  5. Uninstall Problematic Applications
  
  Some apps are incompatible with Windows 10/11 and can cause screen flickering. Think about whether you installed any new software before the screen flashing began or if an app recently updated. In the past, three problematic apps have been Norton Antivirus, iCloud, and IDT Audio.
  
  Across all your applications, make sure you’re running the latest versions. Either update within the app itself or head to the respective official websites and download the most up-to-date release. Alternatively, check the developer’s support page for recently updated apps to see if screen flashing is known as a recent bug.
  
  If this doesn’t work, uninstall the program. To do so:
  1. Press Windows Key + I to open Settings.
  2. Click Apps > Apps & features.
  3. Click Sort by and choose Installation date.
  4. Click the offending app and click Uninstall. You may need to restart your system for the changes to take full effect.
  6. Create a New Windows User Profile
  
  How do you stop your laptop or computer screen from flickering? Well, many Windows 10 and Windows 11 problems can often be solved by creating a new user profile. Screen flickering is one of them.
  
  To create a new account:
  1. Press Windows Key + I to open Settings.
  2. Go to Accounts > Family & other users.
  3. Click Add someone else to this PC (Windows 10) or Add account (Windows 11) and follow the wizard.
  Windows Screen Flickers… No More!
  
  As with most Windows 10/11 issues, no one fix will work for everyone. Hopefully, one of the steps above has solved your Windows 10 or Windows 11 screen flashing problem.
  
  If it is time for a new monitor, there are plenty of productive and fun things you can do with the old one. Otherwise, take it off for recycling so it can rest in monitor heaven.
  
  Second Monitor Keeps Flickering, Flashing or Going Black Randomly (Fix)
  
  We have had an issue with one of our computers’ second monitor that keeps flickering and flashing randomly. To be precise, it goes black entirely and comes back on again repetitively (as if it goes to sleep and immediately wake up again) while the primary monitor works just fine. After trying all possible solutions, including switching to other monitors, fortunately, the issue is solved.
  
  This guide will show you what we have tried to fix the second monitor keeps flickering and flashing issue. Though the solutions we shared in this post worked for us, we certainly can’t guarantee that it will work for everyone else.
  
  Also see: Game Stuttering and Lag on Dual Monitor
  
  The monitor flickering problem is very broad. Solutions are everywhere but usually only a few actually works, because it all depends on the symptoms and the actual cause of the problem. You just have to search for the solutions that describe the symptoms closest to your problem and try each one of them.
  
  Symptom: Second monitor keeps flashing randomly
  
  In our case, the primary monitor is a gaming 144hz monitor while the second monitor is an ordinary one that only has 60hz screen refresh rate. Whenever we use Chrome (or other active programs) on the primary monitor, anything else open on the other monitor would cause the second monitor to flash and flicker (as in going total black and then immediately showing pictures again) randomly every few seconds. Read: How to Change Screen Refresh Rate in Windows 11.
  
  At first we thought it was due to driver issue or loose cable. We tried to update the monitor driver (which is something you should try first regardless if it works), checking and replacing the HDMI cable (or displayport), trying different resolutions, but to no avail. So, we went on to try the settings in the Nvidia Control Panel and found the solution.
  
  How to fix second monitor keeps flashing and flickering issue
  
  Method 1: Select and Rearrange displays in Nvidia Control Panel
  
  Open Nvidia Control Panel from the Start menu in Windows 11 or 10, or by right-clicking the Nvidia Settings icon from the notification icons area in the taskbar. Then, select Nvidia Control Panel. If you don’t see NVIDIA Control Panel while you are sure you are using a NVIDIA GPU, update your graphics driver.
  
  In the control panel, expand Display and select Set up multiple displays. Select and enable the displays you want to use. Then, drag the icons (usually appear as 1 and 2 where 1 is your primary monitor and 2 represents your second monitor) to whichever direction you want.
  
  For example, in the screenshot below, my second monitor will be on the left of my primary monitor. Then, click on Apply. The random flickering or flashing should stop now.
  
  It doesn’t matter if you have configured this before in the default Windows settings, the point is to configure this once again in the Nvidia Control Panel and it somehow solved the flashing issue for us.

  Method 2: Adjust desktop color settings option in Nvidia Control Panel
  
  This is another method you can try to fix the flickering and flashing problem if your monitor is connected using HDMI but not via DisplayPort (you can’t see the option if you use displayport).
  
  In Nvidia Control Panel, under Display, go to Adjust desktop color settings. Select the your primary monitor and at the bottom under the “Content type reported to the display” option, select Desktop programs. At the top, select your second monitor and also change the option to “Desktop programs” as well. Click on Apply. Restart your PC and see if the flashing issue is fixed.
  
  Other recommended solutions to fix second monitor flickering and flashing issue:
  
  Needless to say, you need to always make sure both your video driver and monitor driver are up to date. If you are using an Nvidia graphic card and you cannot find Nvidia Control Panel in your Windows, download and install your graphic driver again from Nvidia.com.
  
  Check the screen refresh rate setting of the second monitor and see if it is set correctly. Right-click on your desktop > Select Display settings > Advanced display settings > Display adapter properties for Display 2 > Monitor tab > Screen refresh rate. If you are using a 60hz monitor, try to change the refresh rate to 60hz if it’s otherwise. Also, try to change it to 59hz and see if it works.
  
  If your monitor offers other types of input port, try using another type of input port. For example, if you are using HDMI right now, try using DisplayPort or DVI if your monitor has the port.
  
  Hopefully this will help you solve your second monitor flickering and flashing issue. If you have other solutions you may want to share with others, let us know in the comment section below.

  - How Gamers Can Fix the Monitor Flickering Issue
  - STEP 1 ALTER THE GRAPHICS CARD CONTROLLER
  - STEP 2 INSTALL GRAPHICS CARD DRIVER
  - STEP 3 CHANGE THE REFRESH RATE
  - STEP 4 CHECK YOUR HDMI OR VGA CABLE
  How do I fix a flickering monitor while gaming? You can adopt many solutions, from installing a new graphics card driver to changing your display’s refresh rate to even investing in a flicker-free monitor. It doesn’t matter what brand of gaming display you have in your setup; this issue can persist if you do not take care of it. Even if you have high-quality, professional monitors like Fortnite pros monitors, you can still run into flickering issues, but there are ways to resolve this issue.
  
  KEY TAKEAWAYS:
  - If your screen flickers, check if your display’s refresh rate is low. Even if you own the top-rated 4K gaming monitor on the market, sometimes the refresh rate may not be able to support the current game and needs to be adjusted.
  - If you update your driver or download the latest version and your screen is still flickering, contact an expert technician to sort out the issue.
  - The most common monitor technology that flickers is the LCD screen.
  Ideally, the flickering of your monitor as you game seems to be more on LCD and IPS monitors. When you play 4K or 1080 games, the monitor exhibits a black display for a brief moment, and then it becomes normal. Although 1080p monitors are considered excellent for gaming, any flash can annoy and disrupt a competitive gaming tournament. This is the case if you have a 60Hz monitor that can flicker more when you try to game in full-screen mode. But you do not have to worry. Below, we are going to discuss how to fix it. If you have a Windows 10 monitor, we have a guide dedicated to resolving screen flickering on Windows 10.
  
  STEP 1 ALTER THE GRAPHICS CARD CONTROLLER
  If your gaming PC has a dedicated graphics card, you can fix this issue by altering your graphics card settings. Follow the instructions below:
  
  NVIDIA
  1. Open NVIDIA Control panel
  2. Display
  3. Advanced Desktop color settings
  4. Desktop Programs
  5. Apply
  For AMD graphics card users, you can follow similar steps and configure the correct settings.
  
  STEP 2 INSTALL GRAPHICS CARD DRIVER
  An outdated graphics card driver or the lack of installing the correct driver can be the root of the problem. In this case, you should update the existing one or install the latest driver.
  
  Now, there are two ways to go about this process – manual and automatic. To simplify the process, you can use Driver Easy or Driver Booster. These two tools can help you update the drivers regularly.
  
  STEP 3 CHANGE THE REFRESH RATE
  Suppose the problem persists after sorting out the graphics card issue. In that case, you can tweak the refresh rate of your monitor through the display settings of your Windows 10. This process can fix the flickering problem. Follow the instructions below:
  1. Open settings in Windows 10
  2. Go to “Display.”
  3. Click “Advanced Display Settings.”
  4. Open Display Adapter Properties
  5. Change the refresh rate by increasing the value. It might save the problem.
  STEP 4 CHECK YOUR HDMI OR VGA CABLE
  When the HDMI cable is faulty, your monitor can blink. That is why it is essential to check the connection of the cable. Top-quality cables will also ensure that you have an acceptable input lag for gaming. Although, compare whether HDMI or DVI or DisplayPort vs HDMI is best for gaming.
  
  F.A.Q.S
  
  What is causing my laptop to flicker?
  
  Some of the causes include an aging laptop, loose internal cables, incompatible applications in new machines, or defective hardware. Also, consider checking your monitor warranty or computer insurance to seek professional help if no other method resolves the issue.
  
  How can I stop my laptop from flickering?
  
  You can start by updating your graphics card’s drivers, download the latest drivers from the manufacturer, disable Windows’ desktop manager, or have an expert sort it out.
  
  Why is my game flickering all the time?
  
  The reason might be that your screen has a low refresh rate. Try to increase it to higher than 75Hz. Alternatively, compare 100hz vs 144hz for gaming monitors with even better refresh rates
  
  STAT: A refresh rate of 60Hz can produce a flickering effect on most monitors. However, most gamers find that monitors with 70-90Hz refresh rates and above enable flicker-free viewing. (source)

  Samsung TV Black Screen With Sound
  
  If you turn your TV on and hear audio but don’t see an image, there are three possible causes:
  - A faulty connection
  - A problem with the unit attached to the TV
  - The television has hardware damages (this problem requires professional servicing by a technician)
  First, double-check the cable connections to ensure they’re safe. After that, consider modifying the television’s broadcasting channel by following these steps:
  
  Copywrite article owner is Readytodiy. com for this article. This post was first published on 2021-05-27..
  1. On your remote, press the menu button.
  2. Choose Live TV.
  3. Select Channel List.
  4. Choose between terrestrial and cable.
  If changing the broadcast channel doesn’t resolve the issue, you may want to contact Samsung’s customer service. However, if your television is wired to an external device, try one of the following troubleshooting techniques.
  
  Rotate through the television’s available sources to confirm the number of impacted input sources. Following that, if you’re using an HDMI cable, run an HDMI cable inspection. To run the exam, do the following:
  1. Go to the Settings menu.
  2. Navigate to the Support menu.
  3. Choose Self Diagnosis.
  4. Pick Signal Details.
  5. Scroll down to the HDMI Cable Test section.
  6. Press Enter on your remote.
  If the cable is deemed defective during the inspection, replace the communication cables between the television and the attached unit. If no visible changes occur, call a repair expert.
  
  Or, you can link an additional device to the same input to test if the issue is related to the connected unit. If the new device returns a picture, there’s a problem with the original device.
  
  Samsung TV Black Screen With No Sound
  
  Due to a connection issue, your Samsung Smart TV is likely to have a black screen and no audio. First, secure any loose links and adequately dispose of broken cables.
  
  If that doesn’t resolve the issue, the problem may be triggered by faults with the external devices. To confirm this theory, click the Menu button on your remote. If the menu appears on your television’s display, the issue is with the connected unit.
  
  Are you confident that the external sources are operating correctly? If you are, the television screen may be black because of outdated firmware. As a result, the firmware must be updated to resolve this problem. If you have access to your television’s home menu, you can update it using the following procedure:
  1. Navigate to Settings.
  2. Choose Support.
  3. Select Software Update from the menu.
  4. Press enter to update.
  Your TV will begin downloading the latest firmware. Once the update is complete, your TV will immediately restart, and the black screen problem should no longer exist.
  
  Samsung TV Black Screen Won’t Turn On
  
  When your Samsung television displays a black screen and doesn’t come on, it’s most definitely due to a power problem. Try checking the wall socket and ensure that the voltage is correct for your TV. Check as well to see if your television turns on when you plug it into a different outlet.
  
  If not, contact a repair technician. This issue could be a hardware malfunction, such as:
  - Faulty driver board
  - Defective LEDs
  - Damaged capacitors
  - Malfunctioning television screen
  Additionally, if the warranty is still active, you can use it to replace the entire television.
  
  Samsung TV Black Screen Won’t Turn Off
  
  If the television doesn’t switch off when you use the remote or the power button, try unplugging it for thirty seconds. Once reconnected, the TV should remain turned off. If it automatically turns on and doesn’t turn off, it’s best to call a repairer.
  
  Or, you can post on the Samsung support forum; a technician will reach out to you to help.
  
  Samsung TV Randomly Goes Black
  
  Is the ambient light detection system disabled, but the TV continues to go dark unexpectedly? If so, it might be necessary to adjust the Motion Lighting feature to see if this improves the visual consistency.
  
  The Motion Lighting feature changes the brightness in response to on-screen activity. When this function is activated, the screen will appear dark, but it’s actually incredibly dim.
  
  To disable this function, open your configuration menu and navigate to Eco Solutions. Once there, use your remote to highlight Motion Lighting and press enter to deactivate it.
  
  Samsung TV Black Screen Reset
  
  If the previous troubleshooting steps were ineffective, consider factory resetting your Samsung TV. This approach is only applicable if you can navigate the Eden menu despite the black screen. Additionally, you need access to a Samsung remote. A smartphone remote application cannot perform these steps.
  
  To perform a factory reset on your device:
  1. Navigate to Settings.
  2. Choose General.
  3. Select Reset and then enter your PIN. Enter 0000 if you don’t have a pin.

  How to stop Mac screen from flickering
  
  Why is my MacBook screen glitching?
  
  Not everyone reported these problems, but there are certainly enough people experiencing this for it to get mentioned.
  
  Screen glitching lines appear on retina and non-retina screens, with Mac users noting that it can affect them when using Terminal or when graphics are enabled or disabled. In some cases, it’s so bad that it makes looking at the screen impossible.
  
  You may be wondering if Macbook screen glitching is a problem unique to older Macs. M1 Macs are powerful and can help handle even the most demanding tasks. Unfortunately, upgrading to a newer machine is not a solution for now. When working on M1 MacBook, you may encounter the same headache — screen lines flickering.
  
  It seems that the issue stems from compatibility problems between the new operating system and the graphics processing unit. On M1 Macs, this usually happens randomly, but it may be because of connecting to an external display or working with some software.
  
  Subsequent macOS updates may have solved this problem, although a workaround or troubleshooting fix is often necessary even then. Hopefully, this problem will be eliminated in flagship M2 Macs that Apple announced at WWDC in June 2022.
  
  For now, though, the problem prevails. So, let’s look at how to solve it and get Mac screens working smoothly without flickering.
  
  There are several potential solutions to the MacBook screen glitching problem. In turn, it is worth trying each one, then seeing whether the screen flickering issue is still present or if one of the fixes has solved it, as each Mac may have a different reaction to this hardware and software interactivity challenge.
  
  1. Restart your Mac
  1. Go to the Apple Menu > Restart.
  2. Or Shut Down, then give it a few minutes before starting it up again.
  2. Update your macOS
  1. Go to the Mac App Store or Apple Menu > System Preferences.
  2. If a macOS update is available — which means you aren’t running the latest version (which could contain the automatic updates needed to solve this problem) — then a new macOS will be waiting for you to download it.
  3. Back up your data beforehand, either to an external hard drive, third-party cloud storage, or iCloud.
  4. Now follow the steps to update the macOS and once your Mac restarts, see whether the screen flickering issue is still present under the same conditions as before.
  Assuming neither of the above solutions has solved this, you can try a few other things.
  
  3. Run maintenance scripts
  
  Not sure how to perform it? You can do that easily using a handy app — CleanMyMac X. It is an all-in-one Mac utility offering a variety of tools including those helping improve maintenance, freeing up RAM, and performing other tweaks to tackle the screen glitching problem.
  
  Maintenance Scripts is a feature that fixes various system glitches and inconsistencies. After you utilize this service, your Mac should run a bit smoother. And, hopefully, Mac screen glitching will disappear.
  
  To use the feature:
  1. Open the app.
  2. Go to the Maintenance module.
  3. Choose Run Maintenance Scripts.
  4. Click Run.
  The free version of this app is available here.
  
  Once complete, restart your Mac for good measure and see whether your MacBook screen flickering has stopped.
  
  Implementing a combination of fixes, such as running maintenance scripts and switching it off and on again (or updating the macOS), should quickly solve this annoying problem.
  
  4. Reset the PRAM (or NVRAM):
  1. Shut your Mac down (not reset, a full shut down).
  2. As soon as you start your Mac again, press the following keys for around 20 seconds: Option, Command, P, and R (simultaneously).
  3. Your Mac will restart with the PRAM (or NVRAM) reset, which should solve the problem. If not, here are a couple more things worth trying.
  It could be caused by caches or out-of-date system logs, and there are solutions for both of these.
  
  5. Adjust Energy Saver settings
  
  If you use MacBook Pro, MacBook screen blinking is sometimes caused by Energy Saver working improperly. If you enable «Automatic graphics switching» in Energy Saver, your Mac will alternate between 2 different graphics chips. But things often break.
  
  Open your System Preferences > Battery.
  Uncheck the box that says «Automatic graphic switching.»
  
  Note
  
  This option is only available on MacBook Pro models that have two graphics systems.
  
  Restart your computer and see if the MacBook screen flashing stopped.
  
  6. Enter a Safe mode
  
  Safe Mode disables a number of services and puts others in a low-key mode. This affects screen parameters as well. Try entering a Safe Mode to see if your screen graphics stabilized.
  1. Shut down your Mac completely.
  2. Hold down the Shift key and turn the Power on.
  3. Keep holding Shift until the Login Screen appears.
  4. This is the Safe Mode.
  By now, you should see if your Mac screen glitching continues.
  
  7. Disable True Tone (for 2018 Macs and newer)
  
  The True Tone technology makes your screen colors look more natural. But sometimes, its color management goes off track.
  - To disable True Tone, open your System Preferences.
  - Click on Displays.
  - Now, uncheck the True Tone box.
  Has your MacBook screen blinking stopped?
  
  Frequently Asked Questions
  
  Why is my MacBook screen flashing?
  
  This issue is sometimes software-related. Open your Activity Monitor and look for unknown processes going on. Also, you can use a hidden software detector in CleanMyMac X.
  
  I’ve tried all these steps, but nothing worked.
  
  One more idea to try is to change your screen resolution. Go to Displays in System Preferences and play around with Resolution settings. Try switching off the default option that’s shown there.
  
  If it’s a hardware issue, how can I fix it?
  
  Maybe it’s the screen connector at the hinge of your MacBook that is off. In this case, you will have to take your Mac to the service. Apple has a free replacement program for this issue.
  
  I hope your screen is acting calm and peaceful now. Thanks for reading.
  
  Let’s figure out why the monitor screen flickers when the computer is running
  
  The most common cause of computer monitor flickering is an incorrectly determined refresh rate. This parameter is changed manually. To go to the screen settings, call the context menu on the desktop. To do this, right-click on any empty area of the screen. In the menu that appears, select the last item — «Personalization».
  
  Your Windows theme settings will open. In the lower left part of the window, find the link «Screen» and click on it.
  
  Here you can change the size of the screen elements. To access additional configuration items, click Customize Display Options.
  
  Please note! You can also use the «Adjust Screen Resolution» link. Both of these items lead to the same menu.
  
  This section sets the resolution — the number of horizontal and vertical dots that make up the image on the screen. To do this, select the desired value from the drop-down list. Opposite the optimal value for the connected monitor, “recommended” will be indicated in brackets. You can save these settings without closing the window by clicking the «Apply» button.
  
  After that, click on the link «Advanced options», which is located on the right. A new window will open in which you can change the basic parameters of the video card and monitor.
  
  The screen refresh rate is set on the Monitor tab in the window that opens. Select the maximum refresh rate available from the list. This parameter is responsible for how many times per second the image on the monitor will be updated. If the frequency is too low or the value is not supported by the output device, the screen will flash.
  
  It is better not to check the flag responsible for access to additional modes. If it is checked, uncheck it. The list of available frequencies will be updated, and you will be able to select the maximum of them.
  
  Please note! It is not recommended to set a refresh rate that is not supported by the monitor itself. You can specify the recommended frequency in the instructions for the device or in its characteristics on the manufacturer’s website.
  
  Outdated graphics card drivers
  
  Computer monitor screen may flicker when incorrect or outdated graphics adapter drivers are installed. You can update this software on the «Adapter» tab. To do this, click the «Properties» button.
  
  In the section that opens, go to the «Driver» tab and click «Update». Then use the built-in search wizard. If, after installation, the system notifies you to restart your computer, do so. A reboot may be required for the software changes to take effect.
  
  Problems with monitor drivers
  
  In addition to the video card, an outdated program may be installed for the output device itself. The update is done in the same way. Close the graphics card properties window and return to the Monitor menu. After that, click «Properties» already in this section and select the «Driver» tab. Click on «Update».
  
  The system prompts you to select one of two software search modes. If you select the first option (automatic search), the folders on your computer will be scanned, and if the monitor driver is not found, Windows will try to find the necessary software on the Internet. If you select the second option, the search will be performed only on the user’s computer, without access to the network. It is recommended to select the first option.
  
  If your monitor came with a driver disc, insert it into your computer’s optical drive. Wait until the search process is completed. It takes from a few seconds to 1-2 minutes.
  
  Damaged cables or loose connection
  
  Screen problems may be caused by a defective VGA, DVI, or HDMI cable that connects the monitor to the computer. To diagnose this problem, check the cord for damage. It must not be crushed or torn. Also check the network cable through which the device is connected to the outlet. Unstable contact with the electrical network causes the image to flash.
  
  If possible, connect the computer with a different cable and check if the screen is flickering. If there are no problems when using a spare cable, they were associated with the cord. Replace it for correct operation of the device.
  
  In addition, it is worth checking whether the cable connector is firmly inserted into the monitor and computer ports. Most VGA and DVI cables have screws that are used to screw the massive connector to special mounts on the device outputs. The cable fixed in this way will not fall out, and the contact will not come off even if you often move the monitor.
  
  Technical malfunctions of the monitor
  
  Another reason why the screen may flicker when the computer is running is a breakdown of the monitor itself. The best solution in this case would be to take it to a service center. Image flickering may be caused by the burnout of one or more CCFL or LED lamps, which illuminate the matrix. Also, the built-in power supply may become unusable.
  
  But you can also eliminate common minor malfunctions at home, using a soldering iron. The most common cause of hardware failure, due to which the image on the screen may flicker, is the failure of capacitors. A faulty capacitor is easily identified by its appearance. Normally, this part looks like a cylinder with a flat top face. If it is convex, the capacitor could lose its original properties, which is why the screen flashes.
  
  If the capacitor breaks and electrolyte flows out of it, the part will not work normally and must be replaced. The most common causes of such a breakdown are power surges and overheating. Because of them, the electrolyte inside the device boils, expands and breaks through the top cover.
  
  Important! Do not repair the monitor yourself if the warranty period has not yet expired. Most devices have seals that will void the warranty if opened.
  
  Such parts are attached to the board with two metal feet. To disconnect them, heat the junction with a soldering iron and pull it towards you. The capacitor parameters are always indicated on the case, according to which you can purchase a similar part on the radio market or in a specialized store.
  
  Solder the purchased capacitor in place of the removed one, observing the original polarity. A contrast strip on the side of the part will help determine the «-«. It consists of broken lines and looks like road markings. Replacing capacitors at home will cost you several times cheaper than the same repair at a service center. Therefore, if you have a soldering iron and minimal experience, it makes sense to try to produce it.
  
  The image in the game flickers
  
  If the screen flickers only in certain games or graphics programs, check the application settings. They are usually found in the «Video» or «Graphics» section. Set the minimum settings, turn off anti-aliasing and anisotropic filtering. Then launch the game and check if the screen is flashing. If the problem is fixed, gradually increase the settings to achieve a balance between performance and realistic graphics.
  
  Pay special attention to the «V-Sync» parameter. Disabling it improves the performance of the game, but the image may flicker. It is recommended to enable this setting to avoid flashing horizontal bars during gameplay.
  
  Important! When configuring some games, there is an item «Automatic configuration detection». Selecting it will set the optimal graphics settings for your system.
