Hello,
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.
Specs- r7 5600x
6750xt reference card
32gb ram, ssd, asus tuf x570
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.
its either some kind of software issue, or the displayport stopped working on my middle monitor because it works just fine with an HDMI cable!?!?
