the 360 can be hooked up to nearly every screen one could imagine . from tv with composite in to plasma 1080 p via dmi , vga analog , digital dvi , rgb scart , component ,whatever. but if its not minimum vga mode 640x480 progressive its no fun at all and games like soul calibur or virtua tennis are lookin lousy.
if ure buying a trisync or vga cabinet u may connet ur box via sub d vga plug . its the easiest way and i displays most of the games in reasonable quality.some may look better in 720 p and a few maybe in 15 k ( i dont like the lowres output of the 360 ) .
