What to do if my GAOMON PD2200 shows no signal and says 'saving power' with an all-black screen?

If your GAOMON Monitor displays a 'no signal' message, 'saving power', and the screen is all black, ensure that the HDMI cables are securely connected. If you're using a desktop computer, verify that the HDMI cable is plugged into the graphics card on the tower, not the motherboard. For Windows OS, press 'Windows+p' on the keyboard and select 'Duplicate' or 'Extend', avoiding 'Computer Only' or 'Projector Only'. If your computer lacks an HDMI port, use an HDMI adapter, recommending DVI/VGA/Display Port/Type-C/Thunderbolt to HDMI adapters over USB to HDMI adapters or USB hubs.
