When using Hi Def on my plasma or my LCD (1080i) with my XBox I found that the picture always shrinks to half of the screen size. Is this normal with Hi def TVs? If so, whats the point to buy a big TV if the picture is going to be halved!? I found this with any game I tried for example soul calibur 2 is one of the few games that uses the highest setting on the X Box. I immagine its because if the higher resolutions, but my PC runs on that LCD of mine and it doesnt "half" the screen!
