What Res does the TV accept without cutting anything from it (I'm talking about your desktop) I think the problem may just be the res you are running ePSXe in

Simply try a few differnt res settings 640x480 should be fine on most sets 1280x960 may be pushing it 960x720 might be OK P.S. these are all multiples of the original PSX res that was only 320x240 in the first place, but the games always look slightly better if you stick to multiples of the original res
