Back again - problem not solved at all
Same thing as before and a lot of people complaining about it, it seems if you google
Running fine for a few days then random black screen and you need to do hard reboot
latest drivers and firmware
win 11 - updated
sfc /scannow verified
Starting to lose my mind as I'd be half way through an edit and it just goes blank.
Still happening but I have a work around - if the driver hangs you unplug and replug the hdmi cable and the gpu starts up again.
Use amernime zone unofficial moddriver can solved all black screen, no signal and driver disabled issue
