What to do if my GAOMON PD1161 shows no signal and a black screen?

If your GAOMON Monitor displays 'No signal,' is saving power, or the screen is all black, ensure the 3-in-2 cables are securely connected. If you're using a desktop, plug the HDMI cable into the graphics card, not the motherboard. For Windows, press 'Windows+p' and select 'Duplicate' or 'Extend'. If your computer lacks an HDMI port, use an HDMI adapter (DVI/VGA/Display Port/Type-C/Thunderbolt are recommended over USB).
