I upgraded from Windows 8.1 Pro to Windows 10 Pro this morning. I have 2 monitors, and both displays seem to be working perfectly in "extend my display" mode.
The problem I noticed is the OS will not allow me to select a different wallpaper for each display. When I right-click and go to "personalize", I'm only given the option of selecting one wallpaper. It does allow the "extend" mode which stretches the image across both screens, so it's clearly recognizing the second display.
I'm not sure if this is a bug, a removed feature, or if there's simply some other setting I'm not aware of.
Anyone else seeing this?
