Same, I got an 7900 XTX, All 3 monitor goes black With power saving mode as they dont received any signal from the card. Cant unsleep it. Need to force a shut down and reboot the PC. Happening every day without any notice but mostly on Idle. If the card got Load from a game this dosen't happen. Driver Up to date. Putting back my 1070 fix the issue. So clearly an AMD driver side one and not component
