This LED-edge TV has by far the worst, most uneven back-lighting I have ever seen on any TV or monitor. On anything approaching a dark screen it literally appears as if there are bright mini-mag lights shining from every corner in towards the center of the screen. Even those are widely varied in shape pattern and intensity.
They are more than bright enough to interfere with normal viewing and glaringly apparent in any scene which has a black background. Friends who happened to be here when we set it up and turned it on noticed the 'weird corner-lights' immediately.
I did update the firmware to current, no change or improvement at all in the awful back-lighting.
I checked the LG55LH90 today for comparison - a full LED-lit TV, 55" and there is absolutely zero visible back-light bleed, on a black screen the back-lighting is beautifully uniform in all respects. The picture is better, as the uniform LED's can darken in darker images and light more in lighter scenes, somewhat replicating the deep blacks of plasmas.
Beware the SAMSUNG UN55B8000 LED unless having the thinnest TV is more important than actual picture quality (why?) and in my opinion or now common sense, be wary of edge-LED lit screens overall. You definitely want to see and check it before buying one, not easy to do in most store environments as even significantly uneven back-lighting may not appear in the brighter lights of a store or in the usual TV store demo modes.
The images/screen really are gorgeous on this TV and if it were not for the severity of the back-lighting issue, it would be a winner, hands-down. It handles fast motion very well with no tearing or blurring that we could find and has "oh wow" clarity and definition. Crystal clear. Sound is ok and fine for TV speakers.
As for the Internet features, it's really not worth paying any extra for on this TV - you are given Yahoo widgets to use and navigate with and it's just not impressive to use - clunky and one nag prompt after another to do or agree to this or that when all you want to do is go online.
The remote is enormous but laid out well and the buttons are fairly large so it's very easy to use as is the menu system in the TV.
I expected it to be programmable to use one instead of my Bose audio and DirectTV remote - as far as I can tell it is not.
Sadly my SAMSUNG UN55B8000 LED is going back to Amazon and I am going with an LED-fully lit LG. My experience with uneven lighting is that it grows significantly worse with use over time.
