Display Devices

1. Dell U2312HM (DisplayPort) 1920 x 1080(p) (60.000Hz) (via DisplayPort)

2. Sony KDL50W800B (HDMI) 1920 x 1080(p) (60.000Hz) (via HDMI)

 

When I'm duplicating my displays, I'm running into major issues with certain games. I will click the game to boot, the screen will flash black and seemingly change to a lower resolution, the game then boots but it is blown up and the picture is pushed way off to the right. If I disable the clone or disconnect the HDMI cable, everything works normally. Both of the displays are 1080p/60hz. I've attached a video to show the issue.
