I recently grabbed an ASUS VG24QE 144hz and now I have two monitors. My old LG, still going strong is my second monitor now hooked up via hdmi. Now, while I had this LG, long before I got my ASUS, it did flicker sometimes. Only in, usually, 2d flat colour environments (ie, camera panning to a blue sky in a movie, facing a colour uniform wall in a video game) would this flicker occur. Now that I have it set up as a second monitor, it flickers everytime something is on the screen of it. Now when I say flicker, I mean it turns off for 1 - 2 seconds then comes back on and does this constant until I move the browser window or whatever that is on the screen, once there is just the wallpaper, it stops flickering. I have tried a few fixes, one of them being disabling AMD overdrive, and that seemed to help but the flicker came back. To reiterate, it flickered before I bought the ASUS, but now it does it perhaps 80-90% of the time.
EDIT: the flickering actually only occurs on HDMI and not DVI. However, my 7950 only has a dual link DVI and HDMI for video output, so If i want two monitors I kind of need it on HDMI.
