I purchased a Panasonic Viera TC-P42UT50 about 3 days ago. I had wanted a P42ST30, but there were none available when I went to the Amazon site, but a blue link said "There is a newer model of this item available" and sent me to the P42UT50. I figured it must be the same, but better, since it's newer, and bought it. This is my first non cathode ray tube model, either LCD or Plasma, so I was expecting an amazing picture experience unlike anything I'd ever seen before. What a HUGE disappointment. I don't know if it's because it's a UT and not an ST (turns out they're different lines...the ST has "Infinite Black ultra" and "Neo Plasma Black 2500", as well as an anti-reflective screen), or if it's a lemon, but the picture was not bright, and yes, I tweaked it seven ways from Sunday trying to get it to perform as advertised. It's just DIM! My 6 year old CRT Sony is brighter than this plasma. I'm simply non-plussed, and extremely disappointed. It has good color and a decent... Read more

I've had this TV for about a week and, after reading some other reviews, had some concerns that it would be too dim for our living room. Thankfully, that has not been the case. Even with four big windows where the sun shines directly on the TV, we can still see the picture just fine. If we really want it to be clear, we'll close the blinds, but it's not completely necessary. Just gotta change the TV's picture settings to Cinema or Game or customize it yourself.

The main thing we use the TV for is streaming online video and the built-in apps work surprisingly well. I figured there would only be very basic functionality in the YouTube, Amazon Prime, Pandora, etc, apps, but thankfully YouTube still lets me browse all my subscriptions (although it goes back to the beginning of my subscriptions after I finish watching one of them, which is annoying). There's no way to comment on YouTube videos, though. I find YouTube works best if you use YouTube's "YouTube Remote" mobile app... Read more

It's been almost one month I have this TV. It's a 42" TV. Initially I thought the brightness from the TV was bit dull compared to the TV I saw in the Shop. But after bit tweaking with the brightness/contrast, it looks much better. I connected the internet using the Ethernet wire and played few YouTube videos connected, wow.. Perfect color and it feels like watching a DVD. I am yet to play with the 3D feature.
Strongly recommend this product

Pros:
Good clarity and deep black
YouTube HD videos are in perfect display
Color saturation

Cons
Sound is OK.
When I placed my SD Card from my Canon Camera, I could view the picture, but couldn't see any video. It looks like it couldn't read the video format.
