I've had this issue a few times but a quick reboot always fixed it. Last night I woke my pc up and my 2 side monitors work but the middle never woke up. Says "no signal " . I've rebooted several times in fact i turn it completely off every night. I've redone the drivers several times. Rolled back to the previous driver and it didn't fix it. Also just disabled hdcp.

I have a 3 monitor setup. The screen that went blank is the center monitor. The pc still works I can boot, I ran a few games on the other monitors just fine. I was hoping that would wake it up but it hasn't. Also changed out the displayport cable. Only thing I really haven't done is try an hdmi cable, which I will when my new one arrives. I see lots of posts about black screens on here and I did my best to check the solutions and try them. Unsuccessful so far.
The monitors are 27" acer monitors. 2k, hdr, ect. I do iracing primarily and again have never really had any issues until this. I rolled back drivers but I didn't do the fresh start thing that deletes all the amd stuff upon update. I'll try that next I guess.
Any other suggestions? I think that I did see an error pop up with the amd window when the screen wouldn't wake up initially.
