pending my purchase of an hdmi cable, i hooked up the nVidia desktop to the LGTV via vga-dvi adapter, worked fine, 1360 x768 resolution
however, im getting "invalid input" for the ATI Desktop, will work up to 40 secs to a minute after boot up, then screen blacks out. used the same vga-dvi adapter that work with the first desktop. what did i do wrong kaya?
