sheepdog26 Swapping out for a higher quality DVI cable is an option. However, as you seem to have 2560x1440 at 120Hz functioning, it is likely not a bandwidth issue. I think very few systems even manage 120Hz at 2560x1440, so that's a pretty large bonus already. Probably better to post on the yamakasi section at the 120Hz forums. They should be in a better position to provide appropriate advice. Plug2k, alientorni If you are having issue with CRU, then the best place to ask for support would be at the software author's official forums by following the link in the original post. I personally have not had a chance to test the utility so can not provide any further help at present.
