Hi, Sorry if this is OT but I'm curious because I'm looking to buy LCD TV too, but how much a viewing angle are we talking about here? Personally, the maximum angle I would sit is 60 degrees (plus/minus) the center of the TV. I wouldn't enjoy watching if it's more than that. Both of these LCD claim, if i remember right, a 172 degree, so that means, near 80 degrees(plus/minus) from the center. I would appreciate you observation from these LCDs. TIA.
they claim to have a 176 viewing angle at the horizontal plane at eye level. this claim does not account for the vertical plane which means that if you plan to wall mount your lcd, then the viewing angle issue will definitely be a problem since you'll be looking up the screen. horizontally, the off axis picture quality shifts dramatically beyond an estimated 45 degrees from center. colors become washed out or "namumuti" beyond the "sweet" spot. unless you watch at eye level, dead center and sit still then you're ok. but if you plan to use the tv to watch movies with family and friends then i suggest that you look somewhere else. also, please take note that they use a hard drive playing hd material showng scenes with vivid and bright colors in showrooms -- which minimizes and masks the problem. try playing a regular dvd especially with dark scenes and you'll have a better appreciation of how weak the lcd panels produce colors off axis.
for lcd, the best picture quality we've seen is from the panasonic lx700. the lower model lx70 too is a lot better compared to the samsung or toshiba. lg (specially the model with the s-ips panel), philips and sony are also good. also, the older toshiba model is actually better than the 3000 series. our only complaint on the panasonic is the lousy on-screen menu and the "plastic" feel of the casing.
anyway, don't take my word for it. i suggest you test the units thoroughly so you'll see for yourself because these things cost a lot of money.
