processor speed and backlight technology.

I am not an expert when it comes to TVs, so when it came to deciding on a new 55 inch HDTV, I simply wanted a great picture from a solid company. I researched quite a bit and decided on Samsung as they have the reputation of a high end company with quality service and reliable products.

When the TV first arrived I was quite pleased. The screen size was ideal for my living room and the picture was good -- not great, but good. The best way to view the TV was by sitting in the center, as the colors did seem to fade a bit if you watched from the side. While 3D was not my motivation for buying this model, I did feel it was a nice addition. And, there is no other way to say it, the 3D is exceptionally impressive. Much better than I expected.

My issue arose in the first two weeks as I noticed that, when viewing darker images, there were large cloudy areas that extended from the edges of the TV. Sports and such was fine as they typically consist of continuous bright images, but the problem would continue to be evident with movies and shows that had a darker theme. The cloudy areas never moved -- they were always stable, and they extended about 1/3 from each edge (direct center of screen was fine).

Rather than immediately send the TV back, I contacted Samsung as I figured they would handle the issue and resolve it (plus I really didn't want to have to go through the return process if it was an issue that could be resolved). The customer service individual was very helpful as they assisted me in scheduling a tech to come and check the issue. About a week later, the tech arrived and I shared the problem.

Size Name: 50-Inch Verified Purchase
I bought this TV for the plethora of glowing reviews it received for its picture performance. I also bought it because it had built-in Wi-Fi. The picture quality is simply amazing! Scenes broadcast in HD look as if they're almost 3D, and by that I mean everything is so clear with unbelievable depth that it makes it look like people and things being broadcast are in the room with you! I previously owned a Panasonic Viera plasma TV, and I can honestly say this Samung LED TV has an even better picture. I didn't think any other current TV technology (except 4K) could touch a plasma. I was wrong. I can't say enough about the picture quality.
Now for the bad/sad part. The Samsung SmartHub and its network ruins the total experience of this otherwise fantastic TV. The wifi connected easily and works pretty well for direct Internet surfing. HOWEVER, when you try to use the SmartHub to view streaming content from Netflix, Vudu, Amazon Instant Video, Blockbuster, etc, it is ABSOLUTELY HORRIBLE! I have upgraded broadband service from my cable provider so my network connection is plenty fast. However, when I tried to use Netflix, Blockbuster and Amazon Instant Video through my new Samsung TV/SmartHub, my streaming video would constantly pause/stop. At first I thought it was my network connection, so I tried to play the exact same HD movie on Netflix through my Wi-Fi enabled LG Blu-Ray player and it streamed perfectly. Let me say that again: The same movie on Netflix - - through Samsung SmartHub = SLOW/PAUSE/STOP; through my LG WiFi Blu-Ray player = SMOOTH, NO HICCUPS (remember, both are using the same WiFi signal being transmitted by my router).

Size Name: 55-Inch Verified Purchase
This is a superb TV with lots of connection options. It is also 3D.

About the 3D. I did not buy this TV for the 3D capability. I think it is a gimmick. After viewing some 3D content off the Samsung app, I still think it is a gimmick. Sure, it is fun to watch for a little bit. But the 3D experience on a TV is not like at IMAX. There are too many other things in the room that distract you from the picture.

However, you should still buy this TV. It costs about $100 more than the 6300 (or 6350) but is well worth it? Why? Because for that money you get "micro-dimming". This feature is worth it! The blacks are really black and the picture works well even in a brightly lit room (and my room has lots of windows). Also, the micro-dimming removes glare. Here is how that works. When the TV is off, there is a lot of glare on my screen. Turn on the TV and the glare disappears. Amazing.

You can read other reviews for the optimum settings. I am connected to a Yamaha receiver using a single HDMI cable on the ARC (Audio Return Channel) and I get great 5.1 surround sound.

What if you pay more? You gain little (some more 3D glasses) by going up one step to the 7100 (7050). Go up to the 7500 and you get better micro-dimming. The 8000 gives you even better micro-dimming. The 9000 is a 4K TV. In my mind none are worth the substantial cost increase for the features that are added.

In summary, for me this TV is the best value in the Samsung line. A superb picture and plenty of features for a very reasonable price.
