When I leave my PC alone for while the screens turns black, which is fine. When I return and move my mouse it comes back on but my second screen stays black and my first screen has a blue overlay over the top of the unlock screen.
I believe this is to do with my dual screens on gts450.
screen 1 is 1920*1080
screen 2 is 1024*768
The blue overlay is on screen one and looks to be the size of screen 2
I can put the password in and press enter and then everything goes back to normal, but how do I fix this issue of a blue overlay stopping me seeing whats on screen?
