Pros + Picture and sound are superb
+ Thin bezel is amazing
+ Menu system is slightly
+ Remote is pretty well laid out
Cons - Back-lighting is not as bright as it should be
Summary I have 13 TVs, from 19" to 62". Four of them are Samsung (32" LCD, 32" LCD, 50" Plasma, and this 40" LED), most of the others are Sony, Panasonic, or Mitsubishi. Every one has been a great TV, but each one is better than the previous. Make sure you understand this TV is the 2011 model, not 2010. It is a UN40D6400UF, not a UN40C6400UF. It is so new that you can't easily find support at Samsung if you use the Product Model Finder. You must search the sight with the correct model number, and only then will you find a path to the support page.
I can only rate this TV on 2D picture quality. I have no use for 3D-TV until they don't require glasses, even though both my PS3's, TV, and a couple of Blu-rays support 3D. As another user noted, the box is slim and that's no joke. I bought my kids a 40" Philips LED TV two weeks ago and that box was slim, but this box was 2" thinner. This TV weighs 22 lbs, while the Philips is 30 lbs. The thin bezel is amazing and makes the TV look like it's all picture.
The menu system is slightly better than my plasma, both well laid out and intuitive. Setup was a breeze and the settings were NOT all maxed out. The remote is pretty well laid out, but not as nice as my plasma and the back-lighting is not as bright as it should be. The picture and sound are superb! Off-angle viewing (vertical and horizontal) is amazing. All my Samsung TV's have touch-sensitive controls on the front of the TV - they look great but are hard to use in most lighting situations. This TV has real buttons on the back of the TV, but you have to memorize the locations by feel.
I would recommend this TV to all my friends and family!! I am so glad I spent the extra $100 to get the 6400 instead of the 6000.
*** P.S. If you will buy this TV I suggest you have compare price before you decide at: www.amazon.com/gp/*************?ie=UTF8&location=http%3A%2F%2Fwww.amazon.com%****%2Foffer-listing%2FB004NZEP2M%3Fie%3DUTF8%26ref_%3Ddp_olp_new_map%26condition%3Dnew%23&tag=***************&********=ur2&camp=1789&creative=390957
Pros Excellent Picture Quality
Thin and Lightweight Only weighs about 22 pounds
Access to Samsung Applications
Cons No WIFI built in
No 3D glasses included
No RCA Audio Out, Need to use a cable to convert the RCA Cables to Stereo
Summary Overall a great TV, however I based my purchase on this review and expected the TV to include the 3D glasses, and it did not which is quite disappointing. CNET usually gets all the specs right, but now I know to double check them.
Pros Good pic quality
Cons It stopped working within 3 months! when I power on the tv, I hear a tick, tick sound from the back.
Called Samsung customer service and it took 1.5weeks for them to showup and told that they need to order the parts, which may take another 2 weeks. This
