Troubleshooting Computer Screen Refresh Issues: A Step-by-Step Guide

Computer users occasionally encounter display problems, such as screen areas failing to refresh or freezing. This guide provides solutions to resolve this issue.

Addressing Partial Screen Refresh/Freezing Issues

This problem manifests as sections of the screen remaining static, even after attempting a refresh. It's often reported when using web browsers or applications like Discord. Common causes include outdated or faulty graphics drivers, Multi-Plane Overlay (MPO) technology, graphics acceleration settings, and Windows update bugs.

The keyboard shortcut Ctrl Shift Win B offers a temporary fix, but the problem may recur. For a permanent solution, follow these steps:

Resolution Methods

Method 1: Managing Graphics Card Drivers

Updating, downgrading, or reinstalling your graphics drivers is crucial.

• Update:

  1. Right-click the Start button and select Device Manager.
  2. Expand Display adapters.
  3. Right-click your graphics card and select Update driver.
  4. Choose Search automatically for drivers.

  

• Downgrade:

  1. Open Device Manager and expand Display adapters.
  2. Right-click your graphics card and select Properties.
  3. Go to the Driver tab and select Roll Back Driver.

• Reinstall: Use Display Driver Uninstaller (DDU) to completely remove the existing driver. Then, download the latest driver from your graphics card manufacturer's website and install it.

Method 2: Disabling Multi-Plane Overlay (MPO)

MPO can sometimes cause display glitches. Disabling it might resolve the issue.

1. Press Windows R, type regedit, and press Enter to open the Registry Editor.
2. Navigate to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Dwm.
3. Create a new DWORD (32-bit) Value named OverlayTestMode with a value data of 5.
4. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers.
5. Create a new DWORD (32-bit) Value named DisableMPO with a value data of 1.
6. Restart your computer.

Alternatively, use an NVIDIA support-provided .reg file to disable MPO.

Method 3: Disabling Graphics Acceleration

Disabling graphics acceleration in your browser settings might help. (Example using Google Chrome):

1. Click the three-dot icon in Chrome's top right corner and select Settings.
2. Go to the System tab and disable Use graphics acceleration when available.
3. Relaunch Chrome.

Method 4: Uninstalling Recent Windows Updates

If the problem started after a Windows update, uninstall that update. Instructions vary slightly between Windows 10 and 11 (check your system settings for the exact steps). For Windows 11 24H2 users, consider reverting to a previous version within the 10-day rollback period.

Method 5: Reinstalling Windows (Last Resort)

As a final option, consider reinstalling Windows. This should only be done after backing up your data. MiniTool ShadowMaker is suggested for creating backups.

Conclusion

These methods offer various approaches to resolving screen refresh problems. Try each method sequentially until the issue is resolved. Remember to back up your data before attempting major system changes.
