hi guys. as the title really. i started using 3 screens on my 5850 recently, and with even a 1mhz overclock, everything goes to hell. this video shall explain. cant get embedding to work, so heres a link: http://youtu.be/snFPpkFMVcQ just wondering if there is a hardware issue. thing being, i love the card, and it overclocks like a bugger, games run perfectly at 900mhz core, 1150 mem. but the desktops flickers everytime the clocks change, or something moves across the screen. if i do need to return this card, has anybody heard of any issues with the 6xxx series along these lines? thanks for any help. EDIT: it has started happening, albeit somewhat reduced, even with amd overdrive completely disabled.
