Once the Task Manager is open, watch the screen for any flickers. </p><ol><li>If Task Manager flickers, then the problem may be caused by a faulty display driver or a hardware issue.</li><li>If everything except the Task Manager flickers, the issue is likely because of an incompatible application. </li></ol><p>If you encounter issue 1, please see "How to fix your display driver" for solutions. If you encounter issue 2, please see "Update or uninstall an incompatible app." </p><h3 data-id="how-to-fix-your-display-driver">How to fix your display driver</h3><p>You can troubleshoot a display driver issue using any of the three methods below.</p><p><strong>Roll back your display driver</strong></p><ol><li>Press the <strong>Windows <em>⊞ </em></strong> + <strong>X</strong> keys and select <strong>Device Manager.</strong></li><li>Select the arrow to expand <strong>Display Adapters</strong>.</li><li>Under Display Adapters, <strong>right-click the adapter</strong>, then select <strong>Properties</strong>.</li><li>Select the <strong>Driver</strong> tab, and then select <strong>Roll Back Driver</strong> and click <strong>Yes</strong>.</li><li>Restart your device.</li></ol><p><strong>Update your display driver</strong></p><ol><li>Press the <strong>Windows <em>⊞ </em></strong> + <strong>X</strong> keys and select <strong>Device Manager.</strong></li><li>Select the arrow to expand <strong>Display Adapters</strong>.</li><li>Under Display Adapters, <strong>right-click the adapter</strong>, then select Update.</li></ol><p><strong>Uninstall your display driver</strong></p><ol><li>Press the <strong>Windows <em>⊞ </em></strong> + <strong>X</strong> keys and select <strong>Device Manager.</strong></li><li>Select the arrow to expand <strong>Display adapters</strong>.</li><li>Under Display Adapters, <strong>right-click the adapter</strong>, then select <strong>Properties</strong>.</li><li>Select the <strong>Delete the driver software for this device</strong> check box, and then select <strong>OK</strong>.</li><li>Restart your device, and Windows should automatically reinstall the driver.</li></ol><h3 data-id="update-or-uninstall-an-incompatible-app"><strong>Update or uninstall an incompatible app</strong></h3><p>The Task Manager test can help you determine if an incompatible app is causing your computer screen to flicker, but it does not tell you which app is causing the screen glitches.

If not, keep uninstalling or updating each app one by one until the problem is resolved. </p><h3 data-id="cables-and-monitors"><strong>Cables and monitors</strong></h3><p>Outside of display driver and application issues, faulty or broken hardware can also cause screens to glitch or flicker. Check all the cable connections from your monitor to the computer to ensure the cables are secure. </p><p>If you have spare monitor cables, you can try replacing your current cables with the spare to see if it stops the glitch screen. </p><p>If you have a second monitor, you can plug that into your laptop or desktop to see if the built-in-display or primary monitor is causing the issue. If the problem is resolved, you know the display is the issue. </p><h3 data-id="schedule-a-hardware-repair"><strong>Schedule a hardware repair</strong></h3><p>If troubleshooting did not resolve your display issues, it is possible there is a hardware problem that requires repair.
