I recently purchased two ASUS MX279H monitors for a dual setup. Both monitors have vertical line noise (the lines jump around). You don't notice it from about 4 feet away. Also, BOTH monitors have done this once - randomly and instantly it will burn in whatever is on the screen and the backlight flickers. This gradually goes away over a period of 2 hours or so. I am running both monitors on DVI to HDMI cables. Playing with settings, inputs, etc. does not help... Surely I didn't receive two bad monitors, right?? Could this be a noise issue from another source?? I have a EVGA GTX 570 Classified gpu, could it be my card going bad?? Please help!
