I have an i7 4770K, GTX970 and 3 x 27" 2560x1440p Monitors. W8.1 x64 Pro. Latest Nvidia Drivers. 

My middle screen is my primary screen and the one I game on. 

Recently I have played 2 games where when I set the game to 1440p and fullscreen, the start bar is still visible at the bottom of the screen. I have been unable to find a solution. 

Witcher 2 and Dragon Age Inquisition. I do run Display Fusion.

Any ideas?
