I just purchased a W4207 on Friday nite (it was actually a replacement of my 37w2 that had a manuf defect) at Best Buy. After playing around (all weekend I might add) with the video settings, I can honestly say that the picture quality is beautiful. Crystal clear (especially in HD). I don't have the numbers with me, but I'd be happy to publish the settings on the forum tomorrow (I even compared my choices with the THX optimizer and it just about matched). In HD, especially Discovery HD, it is like looking through a pane of glass - like I'm really there. VERY impressive.
According to the manual, the TV is 1366 X 768, but it supports all HD formats up to 1080i. It is not 1080p.
There are two features of this TV that I really like that I have not seen b4. 1. Autosource: It is a feature where the TV recognizes what unit you've turned on. For ex., if I turn on my HDTV box, HDMI is automatically selected and it also automatically chooses the best screen format (between FILL & STANDARD). 2. Independent settings: You can choose completely different video/audio settings for HDMI, SVideo, YBR, etc. It is so important b/c my HD settings are NOT good for watching SD.
So all in all, 2 thumbs up. VERY happy so far with this TV.
