Origin and Nvidia issues ?

[foster grant]

OK so I have two monitors a 27" swift and an X34a , and I play my gamas on the x34 , all has been ok until the last 10 days or so...i have both screens set slightly on the darker side ( i dont like bright screens) yet whenever i am on BF4 or BF3 or even TF 2 and when I either exit the game/s or minimize them both monitors go to being rather bright and slightly "pale" almost like there is a "film" over both, so fr it only happens when using Origin , steam and Uplay are not affected , anyone have any idea what is going on please ?

thanks
