There are 3 TVs I can think of.
1. Samsung F8000: there have been 3 reviews so far that have said this TV has no clouding or flash lighting. They also said it has great black levels for an LED, accurate colors and good motion. It also has a really nice design.
- Features include smart TV, Active 3D, micro dimming ultimate (edge lit local dimming) and cinema black (dims the black bars on wide screen movies). The price for the 55" is $2700. However, I'm sure the price will continue to fall as the year goes on.
2. Sony HX950: This TV is full array local dimming. It has blacks equal to or better than most plasmas and the uniformity is pretty much perfect. However, you will have halos (light rings around light objects on a dark background) due to there not being enough dimming zones to cover every pixel. This was one of the best TVs of 2012.
-Features include local dimming, smart TV and active 3D. You can find the 55" for around $3200. Sense this looks like it might be one of the last full array LED TVs, demand will stay high. Therefore, I wouldn't count on the price going down too much more (just look at the samsung B8500).
3. LG LM9600 (or 8600): This is the TV I almost bought last year. Like the HX950, this TV is full array. Unfortunately, this TV does not have the deep blacks and wow factor that you'd expect from a backlit LED. However, if you are not a fan of expensive active 3D glasses, this TV might be for you. LG uses passive 3D which uses much cheaper glasses and is flicker free. The main reason I didn't buy the LM9600 was because of its 2D performance. The light blacks and high lag turned me off. However, if you plan to use 3D a lot, passive 3D might be more comfortable.
-Features include smart tv, passive 3D, nano led and a frameless design. The price for the 55" is $1699-$1999.
I hope this helps. I am personally buying the samsung F8000 later this year. I would highly suggest looking at the F8000 threads to learn more. If you don't mind spending a little more and if you don't mind occasional halos, you should look at the Sony XH950.
