I had the blue halo when I ran 1360 x 765... I got around it by changing refresh rate to 60 - cleared right on up! I am now using a 37" HDTV to play aces high on - *Homer Simpson Voice* mmmmmmmm big screen My tv has an 8ms rate and honestly the only games that I have a problem with are games with dark areas like some levels of far cry - LCDs dont produce dark contrasts well... never so much as an offbeat flicker in IL2 of AH
