Screen flickering issues can be very annoying for users. Usually, this screen flickering issue, prevalent in both Windows 11 and 10 devices, occurs due to either a faulty graphics driver or an incompatible application. Before you do anything else, we recommend you run a small test on your computer to identify the actual reason behind the screen flickering problem.
The Task Manager Test
You can run this small test to identify whether it is a hardware fault or just a third-party app that is causing this problem. You can follow these steps to run the test –
1. Open the Task Manager. Either you can just press the Ctrl+Shift+Esc these 3 keys together or press Win key+X keys, followed by a tap on “Task Manager“.
2. However you open the Task Manager, once it opens up a notice which type of screen flickering issue you are noticing on your computer.
Check whether only the Task Manager part of the screen is flickering or the entire screen except the Task Manager is flickering.
Results of the test –
If the Task Manager is flickering, that means the problem is caused by a hardware fault (a corrupted display driver or defects in the cables).
Otherwise, if your entire screen except the Task Manager is showing signs of the screen flickering issue, a third-party app is responsible.
Fix 1 – Check the cable, and screen for defects
Check the cables and the monitor visually for any defects. Follow these steps –
1. Don’t unplug anything. Now, take a look at the physical health of the cable that connects your monitor to your computer. Check whether you can see any dents, heavy scratches, or torn portions on that cable.
If that’s the case, we suggest you order a replacement cable which costs only $8 to $10 depending upon which type of cable you are using.
2. At first, turn off your computer screen. Switch off the monitor as well.
3. Then, unplug the monitor cable and plug the cable back in.
Test if this works.
Fix 2 – Disable the hardware acceleration
Hardware acceleration can cause this problem. There is no definite way to switch off the hardware acceleration. So, you have to use the Registry Editor.
1. Open the Registry Editor. To do that, search for “regedit“.
2. Then, tap “Registry Editor“.
NOTE – You should create a registry backup before you proceed further. We request you make a backup of the registry on your computer.
Once you have opened the Registry Editor, click on “File” on the menu bar. Then, tap “Export” to create a new backup on your computer.
3. On the Registry Editor page, reach this location –
4. Look for the “DisableHWAcceleration” value.
5. If you can’t find it, right-click on the right-hand pane and click “New” and tap “DWORD (32-bit Value)“.
6. Name the value as “DisableHWAcceleration“.
7. Then, you can double-click on the key to change it.
8. Now, fix the value to “1“.
9. Finally, tap “OK” to save these settings.
After this close the Registry Editor page. Restart your computer. Once the system restarts, the hardware acceleration feature will be disabled on your system.
Fix 3 – Check the GPU connection
If you can’t see any defects in the connecting cable of the monitor, you should check the GPU connection as well.
1. Turn off the computer first and then disconnect it from the power source.
2. After that, open the cabinet. You will see the display cable is connected to the dedicated GPU.
3. Check the position of the GPU on the motherboard. Sometimes, the card gets ejected from its’ seat. In that case, place it properly.
4. If your motherboard has an integrated graphics card (every motherboard has one), attach the display cable to that integrated display port.
5. Now, start up the system. Check whether you can notice any screen flickering issue or not.
If the screen flickering stops, this problem is a graphics-card-oriented issue. Try updating the card or roll back any recent updates.
Fix 4 – Set the optimum refresh rate
Refresh Rate plays a huge role on a monitor. Setting the optimum refresh rate can fix this screen flickering issue.
1. Holding the Windows key and the I keys together opens up the Settings window.
2. Once it opens up, click on the “System” settings on the left-hand pane.
3. Here, you can find the “Display” settings on your right-hand pane. Tap it.
4. Then, tap “Advanced display” to explore it.
5. After that, on the right-hand side, click on “Choose a refresh rate” and set it to any different refresh rate.
[Example – Suppose your system supports 75 Hz. Try setting the refresh rate to 60 Hz.]
Once you have set it to a different refresh rate, the screen flickering issue should stop.
This should fix your problem once and for all.
