Hello,
I have a Radeon RX 7000 XT card in a new computer that is shared between a couple users. When switching between users, the monitors go black. The problem can be resolved by unplugging the monitors and plugging them back in. Sometimes it takes several attempts. I cannot find anything in Windows logs that match up with the times of problem. I updated BIOS and all drivers, reset the Adrenaline software to defaults, and I have also run SFC /Scannow and DISM. The only thing I have found that resolves the problem is switching to the on-board video. Once I do that, the problem never occurs, leading me to believe the problem is related to the video card. Any help would be appreciated.
