Both the U50 and the UT50 lack an anti-glare filter. You need at least an ST50
Watched Total Recall on the new UT50 in the daytime. This is definitely not a TV you want to watch a dark movie in the daytime. It's fine for full screen NFL games (which are bright), but anything dark or letterboxed and you'll see your room reflected in the TV.
It's worth it to me, to save $400 vs an ST50, but if you're a daytime watcher, you won't be happy.
