After update of the driver (AMD Radeon 7900 version 15.200.1062.1004) one my displays is not detected any more. On the other hand I can double my screen. The extension of the desktop is not possible any more. If I switched to the older driver Version everything worked fine again. But after restart the problem popped up again. I updated again and it worked. But then after restart ... No more extension of the desktop.
Somebody told me to remove the driver with DDU logs. It did not help and the old driver got lost. So I cannot manually fix the problem after restart anymore by installing the old and the new driver alternating.
Any kind ideas?
