Odd AMD driver issue

[WhiteNoise]

I'm only posting this in case it helps someone else, but yesterday, I was doing some gaming when I had to leave and pick up my son from school. I turned my monitor off but left the PC running, having exited the game.
When I arrived back I found that my main screen was not receiving a signal from the video card. My second screen was though and it was acting as my secondary screen.

So I use a 55" LG OLED as my main screen and a 16" touchscreen as my second monitor. Moving forward, I will call them screens #1 and #2.

I'm running HDMI cables from 7900xtx to both screens. I tried rebooting first and my screen #1 was not detecting any signals but screen #2 was still showing the wallpaper and layout as if screen #1 was on. That made me think that the video card was still outputting both signals. If I unplugged screen #1 from the back of the VGA then screen #2 would become the main screen. Plug screen #1 back in and screen #2 would become the second monitor again but my TV was not receiving a signal.

Next, I swapped out the HDMI cable which immediately solved my issue. Screen #1 was now receiving the signal and I figured my HDMI cable must have gone bad.

Everything was fine until later when I had to pick up my daughter. This time, I left both screens turned on. When I got back it looked like my monitors were asleep. I wiggled my mouse and only screen #2 woke up. There was no way a second HDMI cable went bad. Still, I swapped cables again and it didn't work. Screen #1 was on but wasn't receiving a signal. I tested the PS5, and Switch through the TV and they both displayed fine. At this point, I wasn't sure if maybe one of the ports on the video card died, but after testing them with screen #2, they all worked. Yet screen #1 would not work with any ports, even when trying the display ports.

At this point, I decided to update the video card drivers. AMD had just released a new set. I installed them but unfortunately, that did not solve the problem.
Then I went into safe mode and used DDU to wipe the AMD drivers. After rebooting, both screens came alive. I then made sure Windows was fully updated and did a fresh install of the AMD drivers.

So I think this is a driver issue. I think it may be related to when my monitor goes to sleep (which I have disabled now). But cleaning the drivers from Windows, and then reinstalling solved the issue. I have never seen this problem before.
It was odd that the video card would output to my smaller 1080p screen but not my larger 4k screen. So very strange.

Has anyone else experienced this?

If you're trying to clean out AMD drivers, you gotta use their driver cleanup along with DDU in safemode. Using DDU alone isn't enough.

Typically I'll DDU, ADU, and offline install new drivers and that gets everything going.

@Toothless Im good for now but I will keep that in mind if it happens again. I'm just glad its working.

Have you tried unplugging the power and reseating it again? I have set my monitors to sleep at ten minutes and the computer at 30 minutes. If I leave it like that say overnight my main monitor (Samsung U32J590U over displayport and a 6950xt) will be completely non-responsive until I unplug the power cord. I've assumed it has something to do with displayport (or a new standard), because it didn't happen when I was using HDMI only (Geforce 3060ti).

I had weird issues with my LG monitor too. Like you I have a 7900xtx and did the usual troubleshooting. The video output worked on a DP and HDMI connection to another monitor so I focussed on the LG. The LG has 4 HDMI ports and I found I only had output on one of them. People suggested that the ports not working were shorted out but I'm wondering if this is an LG thing.

No, I didn't try that but when I placed the HDMI cable into another device, the monitor detected the signal and came to life. Placing that same HDMI cable back into the video card and no signal was detected.

I was worried that it could be my LG as well and considering the price of this thing, I would have been crushed, but I tested all of the HDMI ports and they all work with other devices like my ROG ALLY, PS5 and Nintendo Switch. So I do believe it is the video card. More precise the drivers.
