Two Monitos, one look dimmed (darkened when both are plugged)

I have an Asus and Samsung monitor, when the samsung its plugged alone its look great, when I plug the Asus and Samsung together for desktop expanded the Samsung just look dimmed, like darker, and lose allot of color in the sense it look less vibrant, and the Asus look like Samsung does when its alone, I tried swapping ports but make no different

For GPU I have a gtx 780 ti, PSU 1000watts + titanium, asus Maximus Formula VI and Intel i7 4770k
