I currently have four monitors, Monitors #1 and #2 will show the desktop wallpapers but Monitors #3 and #4 will remain with a blue screen while the computer is locked. This doesn't seem to make much sense if two of the monitors can show the wallpapers then the rest should be able to too. Is there any way this can be changed, I'd love to be able to see my desktop wallpapers on the lock screen for all monitors, rather than having two of them bright blue while the other two have pretty wallpapers!

I'm on Windows 8.1, with StartIsBack.

I uploaded a picture! The desktop backgrounds work on all four, but only on monitors #1 and #2 in Windows Monitor Configuration, #3 and #4 seem to just stay the default color.

Any luck?
