Before/After, Full Screen Not Working on Primary Monitor

Problem: When using my primary monitor, the 'Before' half of the 'Before/After' mode is greyed-out (like in the links below) and the 'Full Screen' mode just shows a black screen. When I drag the LR window to one of my old, crappy monitors, everything works correctly. Then I drag it back to my primary monitor and it stops working again.

I have tried the solutions presented in the following forums - which included copying history step to 'before', updating graphics drivers, and turning off GPU acceleration in LR - none of which helped.

Windows may have installed a corrupt/incompatible display profile.  To quickly test that: http://www.lightroomqueen.com/articles-page/how-do-i-change-my-monitor-profile-to-check-whether-its-corrupted/

Wow, that fixed it right off the bat. Thanks!

So is that change in color profile going to affect anything else on my computer? To be honest, I don't really know anything about color profiles.

Most likely that change to the generic sRGB won't make color accuracy any worse than it was. (Most modern computer displays are reasonably close to sRGB, unless you have a more expensive wide-gamut display.) But if you want to ensure higher color accuracy, you should calibrate your display (see the bottom of that article).
