Solution

White borders on LCD monitors can be caused by backlight bleeding (or uneven backlighting) or LCD panel delamination, but can also be caused by the following:

  • You may be using outdated and/or corrupted drivers
  • System files on your machine may be corrupt and/or mismatched with other files
  • You may have a virus or malware infection on your device
  • Some applications or services running on your machine may be causing your monitor to behave strangely.

Before trying any of the methods below, start with these solutions first, iterating through each one until it resolves the problem.

  • The first resort is restarting your system, which can fix temporary glitches.
  • Install all available Windows or macOS updates until your machine reports it is up to date.
  • Install any driver updates. The update will remove the faulty files and replace them. If updating doesn’t work, then it may not be compatible with your hardware configuration.
  • Make sure your screen resolution is set to the recommended setting in Windows Display Settings. Do the same in your graphics card’s control panel.

If none of the above work, your monitor may have a hardware issue causing this problem. As a temporary workaround, try the following:

  • Try waiting for the border to disappear. This may take hours or days depending on how severe the problem is. To expedite the fix time, try running this YouTube video to see if the problem is resolved.*
  • If you’ve waited hours or days and the border still persists, backlight bleeding may be the culprit. To minimize this issue, lower the brightness in your monitor’s OSD.
  • Be aware that layers from your monitor’s LCD panel can separate as a result of extreme heat or cold temperatures. Use the monitor at a safe temperature.

*To prevent irritation to your eyes that could result in headaches, motion sickness, or seizures with epilepsy, play the video at 50% speed.

If you tried all of the above solutions and the border persists, your monitor may need to be serviced. If it’s covered under the warranty, you may be eligible for repairs or replacement.
