I'm thinking of getting a VGA HD cable so I can hook my 360 to my computer monitor. My computer is a VGA LCD 17" flat panel, but it isn't a widescreen, it has a native resolution of 1280x1024. My standard tv is only a 20 inch, and about to crap out on me. Will it look good on this monitor. I can't afford a HDTV right now, but really want good looking picture.
