To address the issue with your screen contrast changing when playing videos in full-screen (.avi format) and reverting back once exiting full-screen mode, you can try the following troubleshooting steps:

Possible Solutions:​

• Update Graphics Drivers:
• Ensure your graphics drivers are up-to-date. Visit your device manufacturer's website or use Windows Update to check for the latest drivers.
• Disable Automatic Brightness/Contrast Adjustments:
• Go to your graphics control panel (NVIDIA Control Panel/AMD Catalyst Control Center/Intel Graphics Command Center).
• Look for automatic brightness/contrast adjustments and disable them if enabled.
• Adjust Video Player Settings:
• Check video player settings for any video enhancement features that might be causing the contrast changes.
• Adjust Windows Display Settings:
• Right-click on the desktop and select Display settings.
• Disable or adjust any display setting related to brightness or contrast adjustments.
• Disable Adaptive Brightness:
• Go to Control Panel > Power Options.
• Click on Change plan settings next to the current power plan.
• Select Change advanced power settings and locate Adaptive Brightness under Display settings.
• Check Monitor Settings:
• If your monitor or laptop screen has built-in display settings, adjust them to see if the contrast issue is resolved.

Additional Tips:​

• Use a different video player to see if the issue persists.
• Run a video player in windowed mode and check if the contrast issue occurs. By trying these steps, you can troubleshoot and hopefully resolve the auto-contrast adjustment issue while playing full-screen videos. If the problem persists, feel free to provide more details or specific system information for further assistance.
