Left uses HDMI and right uses DVI.
I've tried everything possible except for trying a new video card...
Does this mean it's a video card issue?
Sometimes my right screen (the new one), flickers horizontal lines frequently too, especially when I'm idle. So it's almost definitely my GPU..but it works fine if I restart...but every time I boot up (not including restart), it happens.
I have a MSI 7950 TWIN FROZR III 3GB.
