Ok, my pc's hooked up to my 52" hdtv via the hdmi/dvi in on the back of the tv, whenever I start company of hero's demo I get "failed to find a working full screen mode" has anyone had this problem playing on a tv before? and it's not just COH it's all the games I try to play. The video card im using is an 8600gts oc and the resolution is set to 1280x720 (its the only resolution avaiable. Thanks for your time
