T5 Black Screen on Secondary Monitor

[shrek2.mov]

So I did some looking into about how to get BO1 to run on a secondary monitor and updated my .cfg file accordingly. However when I now run the game like this, my 2nd monitor is a black screen, except I can hear all the sound perfectly. I've tried updating my graphics card driver, I've tried doing the cmd lines for r_fullscreen 0 then vid_restart but keep coming up with the same result. The game works fine on my primary monitor it's just the smaller one of the 2 that I have. Is there a fix for this?
