Hi minuk kim,
thank you for posting on the Microsoft Community Forums.
Screen flickering and pixelation issues can be caused by a variety of factors, including outdated drivers, hardware issues, or software conflicts. Here are some steps you can take to troubleshoot the issue:
- Update your graphics drivers: Go to the manufacturer's website and download the latest graphics drivers for your device.
- Check for Windows updates: Make sure your device is up to date with the latest Windows updates.
- Run a hardware diagnostic: Use the built-in Windows hardware diagnostic tool to check for any hardware issues.
- Disable hardware acceleration: In some cases, disabling hardware acceleration in your browser or other applications can help resolve screen flickering issues.
If none of these steps resolve the issue, you may need to contact your device manufacturer for further assistance.
Hope it helps.
Best regards,
Lei
