Troubleshooting Video Display Issues
Use this guide when: You have turned on the system, plugged in the HDMI and nothing is displaying on the screen.
- Cable Check: Ensure HDMI/USB-C adapters are securely connected and undamaged. Also, ensure the adapter and HDMI cable are securely attached.
- Check Projector: Ensure the projector is on; sometimes, it does not turn on with the system. If that is the case, look for "Display Controls" or "Projector Power" on the touch panel to turn on the projector.
- Input Source Verification: Use the TV or projector controls, usually on the touch panel, to select the correct input (e.g., HDMI or Laptop).
- Check Laptop Display Settings:
- Windows: Press Windows + P → Choose Duplicate or Extend.
- Mac: Go to System Settings > Displays → Click Detect Displays.
- Power Cycle: Restart the laptop and power the projector or TV off and on.
- Test with Another Laptop: This helps determine if the issue lies with the laptop or AV system.
