Picked up the 27" high-end stock iMac yesterday. It's mighty beautiful and damn powerful too (runs all my games on max and never dips below 60fps!) Problem is as it was downloading those games I noticed some display artefacts and I was wondering if other users could view this screenshot and tell me if you get the same problem as my photo; (click to enlarge) URL> http://satansam.co.uk/ftp/IMG_6844.JPG The blue graph lines seem to repeat over onto the blue background. The screenshot produces the same effect under Windows 7 as it does OSX. There are no other problems, as I said games (TF2, L4D2, Portal 2, Burnout Paradise etc) all run totally fine. If it's a common problem then I'll just stick with it. Else I'll make use of my Apple Care and take it back. It's the only thing that's dampening this brilliant machine .
