Native brightness not working?
- Ensure DDC-CI is enabled in your monitor's settings menu
- Try using a different video cable (DisplayPort/HDMI recommended)
- Some laptop displays don't support DDC-CI — use software mode instead
Multiple monitors not detected?
- Disconnect and reconnect displays
- Restart the application after connecting new monitors
