“No Signal” Troubleshooting (for PD2200)

If your GAOMON PD2200 shows the yellow GAOMON logo → “No Signal” → “Power Saving” → black screen with the indicator light turning yellow or red, follow these steps:

• Step 1: Check Cable Connections
  • Make sure the USB, HDMI, and Power cords are all securely connected.
  • Use the included power adapter, HDMI cable, and USB cable to connect the PD2200 to your computer.
  • Double‑check that the cables are firmly inserted on both ends.
    
• Step 2: Verify HDMI Setup
  • If your computer does not have an HDMI port but you want to connect two monitors, you’ll need an HDMI adapter.
  • See the guide: Precautions for Using HDMI Adapter.
  • On a desktop PC, plug the HDMI cable into the graphics card, not the motherboard.
    
• Step 3: Adjust Display Settings (Windows Only)
  • Press Windows + P on your keyboard.
    
  • Select Duplicate or Extend mode.
    
  • Do not choose “PC screen only” or “Second screen only,” as these will cause a no signal error.
• Step 4: Test with Another Computer
  • If the issue persists, connect your PD2200 to another computer that has a native HDMI port.
  • This helps confirm whether the problem is with the tablet or your computer setup.

Quick Checklist

• USB, HDMI, and Power cords are firmly connected
• The HDMI cable is plugged into the graphics card (desktop)
• Display mode set to Duplicate/Extend (Windows)
• Tested with another HDMI‑enabled computer
