Signal not detected in device.
Signal not detected in device.
Recently I've faced this problem multiple times. On my PC, suddenly the screen goes black and doesn't turn back on—something called 'DP no signal'. When I try to restart, it prompts for the Windows password, then after a couple seconds the display shuts off again and the GPU fans stop working. I've checked all the usual troubleshooting steps and similar forums, but it seems unrelated to the monitor or cables. Previously it would resolve by itself, now it's stuck. My system specs are: Ryzen 5 5600, Radeon 6750 XT, 16GB DDR4 RAM, M.2 B550 M.Pro.
