I have an xbox 360 and I really want to play in high def. Computer moniters are basically the same thing as hdtvs arent they? so should I get an HDTV or should I go for the monitor and save some $$ ? would there really be a noticable dif in picture? Also I've beeen lookin at Olevia's tvs it says on their site that it supports digital tv and widescreen movies in 1080i. does that mean i would be playing xbox in 1080i?
