It is even more complicated than that. Samsung makes:
-lcd tvs
-lcd pc monitors
-lcd pc monitor/tv combo
and
-lcd pc monitor/hdtv combo (called a mutli-function display)
A couple of days ago I bought the syncmaster 151MP. It is the 15 inch hdtv/pc monitor combo. It was pretty pricey, but i'm hoping it will have a faster pixel response time because of the high definition tv tuner. I havent tried it as a pc monitor yet because the parts for my new computer haven't arrived yet.
So far though, it looks pretty good. I've hooked it up to my ps2 and notice no bluring or ghosting in medal of honor on it, but the ps2 outputs a horrible resolution so it may not be evident yet. As soon as I get my new box hooked up I'll post a more comprehensive review.
