ASUS Dual monitor, acting funny.

[eRoD]

Hello everyone, Eddy here. It's been a away since i've posted. My dual monitor set up is acting a little funny. I recently moved upon reconnecting everything something went wrong. My computer is a ASUS G75vw with a 3gb graphics card (NVIDIA GEFORCE GTX 670M) both monitors are ASUS PA248Q. The monitor with the correct is connected via HDMI and the monitor that darkens images is connected via displayport.

Please help. I've linked a video showing the problem.
