Tom,
I bought a 32″ Sony Bravia LCD, which is a better set than the Sharp, and I can tell you that SD sucks big-time. I won’t even show my stuff on this monitor, because it looks so much better on my 36″ Sony CRT monitor. I don’t know if it’s true, but I’m told that SD looks pretty bad on all HD monitors. Even SD cable TV looks bad on the Sony. Lots of artifacts and mosquito noise.
