Not sure if this is the place to post this but seemed best place, perhaps...

So I recently bought a BenQ XL2720Z Monitor. I previously had a dual monitor setup with a Samsung and old NEC. Both were DVI hookup. Then I bought a GTX 970 that only had a single DVI port on it, so I bought a temporary DVI to DP cord to hook up my Samsung.

Now, I have the BenQ, so it's temporarily using the DVI to DP hookup, and the Samsung is on straight DVI.

Here's the issue. Previous to the BenQ I never had any issue with games "locking" the mouse to the game. My mouse would never slide off into the other monitor unless I alt tabbed out of the game. NOW, it ALWAYS does, on EVERY game. And I am horribly confused on why, because nothing has changed. It's the same cables, plugged into same slots on GPU, using same drivers, on the same PC. Only thing changed is the monitor.

This is driving me nuts, as I've tried closing programs, fiddling with things to figure it out, to no avail. It's like something has no decided all on it's own I can slide right out of games into other monitor. Even using programs to "lock" the mouse is having very spotty success. Any assistance on this would be grand.
