Pros Really impresses with 3D capability
There is very little or no aliasing or motion blur
Set-up of the TV was easy and intuitive
Cons High price
Summary Samsung calls this TV "Future-Proof." Because of the lack of true 4k source material, one might call this TV present-proof, as well. One would be wrong.
The signal upscaling on this unit takes almost anything you give it, and makes it look incredible. Understanding, as I do, that upscaling is no substitute for providing the intended signal to a device, I was quite concerned that I might have an expensive TV with a terrible picture until more 4K footage is available. My Charter HD channels' pictures look so real, they're almost surreal. Blu-Ray, Blu-Ray 3D, and Charter 3D look perfect. The only 4k footage I have viewed was offered on YouTube, so I have no idea whether it is actually 4K by the time it reaches the TV. Footage "mastered in 4K" but delivered on a Blu-Ray cannot be 4K, as UHD has twice the horizontal and vertical resolution of the 1080p HDTV format, with four times as many pixels overall.
There is very little or no aliasing or motion blur, even with small patterns in the image and fast motion. The only time I have seen any aliasing was when watching a streamed episode of Walking Dead. When actors' walked in front of a chain link fence, there was quite a lot of aliasing around their heads. I attribute that issue to dubious signal strength, as the HD signal may be reduced to standard definition if it determines that your WiFi can't deliver the goods.
--- SET-UP: The set-up of the TV was easy and intuitive. I was able to watch cable TV, watch a Blu-Ray, play Play Station, or go on-line within 30 minutes of the delivery man's departure.
--- EXTERNAL HUB: The external hub scared me, at first, because I didn't think I could connect my audio system to it with the cables I had on hand. Samsung included adapter cables which solved that problem! I imagine we will be able to purchase another external hub in the future when cables can support better data transfer for true 4K viewing. For now, it's quite nice to have 4 HDMI ports. I have the hub tucked practically out of sight behind the TV, though the One Cable To Rule Them All (or whatever it's called!) is long enough to be placed elsewhere (~10 ft.).
--- 3D: The unit really impresses with its 3D capability. Four pairs of comfortable glasses are included. Having the family (age 10 - 53) gathered around ooooh-ing and ahhhhh-ing over 3D movies is reason enough to own this TV.
--- VOICE RECOGNITION: Neat trick! The voice command menu sometimes launches unexpectedly, but someone in the room might have said something that sounds like, "Hi, TV!" I have left it activated, for now, but I find that I'd rather use the smart remote.
--- MOTION DETECTION: I have tested and disabled this feature. I find that using the smart remote is the easiest way to control the TV.
--- REMOTE CONTROL: Oh, the things you can do with a finger swipe! I accidentally discovered that I can fast forward (right), reverse (left), play (up), and go to live shot (down) my cable programming with the smart remote. Another, more standard universal remote is included. A small QWERTY keyboard would have been nice.
A little background: I am a video editor, but I am using this TV exclusively for personal viewing. I have had assorted roles on TV sets and on location (lighting, camera assistant, and audio), as well as in the control room. I am currently working on a degree in Media Technology. Professionals in "the industry" with whom I've talked have mixed feelings about 4K, but agree that it is the next thing.
I will gladly answer any question you have about this TV if you'll leave a comment on the review. I will update this review as I learn more about my new TV.
