Hi @roman1010,

Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand you're dealing with a tricky issue after a Windows update. Here are some steps you can try to resolve the pink/purple screen problem:
 

Check Display Drivers:

• Go to Device Manager (right-click on the Start button and select Device Manager).
• Expand Display adapters, right-click your graphics card, and select Update driver. Choose to search automatically for updated driver software.

Roll Back Drivers:

• If updating doesn’t work, you can try rolling back the driver. In Device Manager, right-click on the graphics driver, select Properties, then go to the Driver tab and click Roll Back Driver if available.

Check for Windows Updates: 

• Ensure your Windows is up to date. Go to Settings > Update & Security > Windows Update and check for updates.

Run System File Checker:

• Open Command Prompt as an administrator (right-click the Start button, select Command Prompt (Admin) or Windows Terminal (Admin)).
• Type sfc /scannow and press Enter. This will scan for and attempt to repair corrupted system files.

Check for Conflicting Programs:

• Uninstall any recently installed programs, especially the lockdown browser, to see if that resolves the issue.

Boot into Safe Mode:

• Boot into Safe Mode to see if the issue persists. If the screen works fine in Safe Mode, it could indicate a software conflict.

Reset Windows Defender:

• If you still face issues with Windows Defender, you can reset it:
  • Go to Settings > Apps > Apps & features.
  • Search for Windows Defender, click on it, and select Advanced options. Then click Repair.

Check Hardware Connections:

• Ensure that the display cable (if accessible) is securely connected, and consider checking for hardware issues if the problem continues.
