Troubleshooting

The overlay doesn't appear

Check these in order:

  1. Make sure protection is enabled in the dashboard (the toggle should be on)
  2. Check that the overlay is enabled for the correct monitor
  3. Verify the Max Dim Amount isn't set to 0
  4. Try restarting the app — right-click the tray icon and select Restart

The overlay flickers in games

This usually happens with exclusive fullscreen games:

  1. Switch the game to borderless fullscreen mode (recommended)
  2. If the game only supports exclusive fullscreen, OLED Guard will automatically pause and resume — some flickering during transitions is normal

High GPU usage

  1. Switch to a lower quality preset (Low or Medium)
  2. Reduce the Render FPS in Advanced Settings
  3. Disable protection on monitors you don't need it for

Normal GPU usage should be under 2% on a modern GPU at Medium quality.

The app doesn't start with Windows

  1. Open the dashboard
  2. Go to Settings
  3. Enable Start with Windows

SmartScreen blocks the app

Windows SmartScreen may block newer apps. Click More info then Run anyway. This only happens once.

Multi-monitor issues

If a monitor isn't detected:

  1. Check that the monitor is connected and recognized by Windows (Settings > Display)
  2. Restart OLED Guard Pro
  3. If using a dock or adapter, try connecting directly
