i used a HDMI cable in the past and all was fine, i used VGA for months now with no prob. i now have a new pc and wanted to be able to flick back and forth. i connected the hdmi to the dvi (7800gt) on this monitor and while the pic is there, it looks awful. it is blurry as anything. i swapped the cable back to my other pcs card (9600xt) (the one i used it on originally) and thats the same. both are fine with VGA but i want to use hdmi with it is there anyway to find if its the cable or the projector short of buying a new cable?
