Yeah I tried Powerstrip, but couldnt get the new resolution to come up after restart. Did my test through the nvidia drivers. It wouldnt stick, but stayed up long enough to test.
If the ebay guy says it woirks, maybe its just a matter of getting the right advanced timings which I havent screwed around with yet. Btw 60hz gave me a jumpy image, but 58hz seemed to give a stable image for anyone trying.
