I have a Radeon HD 7800 Series card servicing two monitors. I just upgraded to Driver version 15.300.1025.0, and I completely lost the Windows 10 Pro ability to display different background images on each monitor, a nice 10 feature since I am a photographer.
Thanks for your help.
Ignore question - figured it out myself.
Futzing earlier with Device Manager->Monitors, I noticed that 'status' on both monitors were 'disabled.' So, after 'Enabled' and restart, monitor behavior is now back to what it was just before Driver Ver 15.xxxx was installed.
Yay - SOLVED (I hope).
