- How:
- Go to Settings > System > Display (Windows).
- Set the resolution and refresh rate to recommended values (e.g., 1920×1080, 60Hz).
- Test fullscreen mode again.
- Why It Works: Mismatched settings can overwhelm your display, leading to a black screen.
Step 4: Run in Compatibility Mode
- How:

Step 6: Test Windowed Mode First
- How:
- Launch the app in windowed mode (check game/app settings or press Alt + Enter).
- Gradually switch to fullscreen to isolate the issue.
- Why It Works: Windowed mode uses less GPU power, helping identify if fullscreen is the problem.
Step 7: Check Hardware
- How:
- Ensure all cables (HDMI, DisplayPort) are secure.
- Test with another monitor or PC to rule out hardware faults.
- Update GPU firmware if available.
- Why It Works: A failing monitor or GPU can’t handle fullscreen demands, resulting in a black screen.
