This tv was replaced by the Samsung MU7000

Type : LED
Resolution : 4k
Refresh Rate : 60 Hz

The 4k LED UHD Samsung KU7000 Series has a good enough picture quality for most content but lacks in a few areas. It handles fast motion decently and it feels responsive when playing video games. Unfortunately, HDR performance is average, judder is present in movies and the picture deteriorates when viewed from the side.

Design

Score components: Subjectively assigned
Samsung KU7000 Design Picture
Curved : No

The Samsung KU7000 is a great looking TV. Its frame looks like it is made of metal, the classic looking Samsung stand now shares a new style with a shiny reflective finish and the textured back of the TV adds a nice touch. The TV is also quite thin. Compared to the KU6300, it looks better.

Stand
Samsung KU7000 Stand Picture

The KU7000 shares the same kind of stand as many other Samsung TVs but with a slightly different new cut and finish.

Footprint of the 55" TV stand: 37" x 13.1"

Back

The TV appears quite thin from a 90 degree angle. The bottom part is thicker than the top part.

7.4

Picture Quality

Score components:

Watching movies on the KU7000 is average. The dark scene performance is quite good, but limited by lack of features. Judder is experienced when watching movies and motion interpolation options are limited. The TV can play HDR content, and does provide richer colors but the highlights can't get very bright. The colors are quite good out of the box, and the TV looks clear when displaying content from DVDs to 4k video. 

8.6 Contrast
What it is: Brightness difference between white and black. This is the main component of picture quality.
When it matters: Always, but especially when watching dark scenes.
Score components:

The KU7000 is bright enough for normal SDR content but well below the HDR standard of 1000 nits for highlights. There is no local dimming. With an HDR signal, the 2% window dims, but on a standard signal, the brightness remains constant across all window sizes. The peak brightness is lower than the KU6300.
Update: Updated with sustained brightness.

Good value: < 2%
Noticeable difference: 1%, but keep in mind that it varies a lot by unit, even of the same model; yours likely will not end up exactly like ours.
:
0.684 %

The black uniformity is really good. Due to the way the TV is edge lit, there is a small 1/4" bright strip extending part way across the top and bottom edge. This should not be an issue for most content.

9.0 Gradient

When it matters: Details in shadows, sky and skin tones. Matters more for HDR content.
Score components: Subjectively assigned
Samsung KU7000 Gradient Picture

Good value: 10-bit.
Noticeable difference: 1 bit.
:
10 Bit

Update 11/09/2016: Our original test was showing 8 bit gradations due to incorrect drivers on our system. After some correction to our test apparatus, we have retested the color depth and found that it is able to display a 10 bit gradient smoothly. There is some little imperfections in the darker green, but nothing that could make normal viewing problematic.

Samsung KU7000 Smart TV Picture
Smart OS : Tizen (2016)

The Samsung KU7000 offers an impressive smart interface performance that is both smooth and responsive. The TV comes with a fairly fast CPU and memory which allows applications to load quickly even when heavily multi-tasking, showing no hiccups at all.  Also, the operating system supports a great deal of different applications such as Netflix, Amazon Video, Youtube, and many more, making it a very polished smart interface. As for the inputs, the Samsung TV offers many inputs of different variations making it capable of plugging all your devices in it. Be careful though, if you want to use the full capability of the TV make sure you use the HDMI 1 port as it's the only port that supports HDMI 2.0.  

When a new device is detected (such as when a computer is woken from sleep while plugged into an HDMI port) the TV automatically switches to this device. This may be an annoyance if you are watching other content at the time.

Looking at the TV from straight on, the TV controls are located at the bottom right of the TV. This small button offers many basic operations such as changing the volume, inputs, and turning the TV on or off. This button is still accessible even if the TV is wall mounted.

Remote

Remote : Smart

The remote is identical to the Samsung KS Series remote. It's comfortable and is very easy to use to navigate through menus. It also has the voice command functionality that the KS Series remote has, which is a nice addition. This remote, compared to the Samsung KU6300, is somewhat better and has the voice command functionality.

Differences between Sizes and Variants

We tested the 55" (UN55KU7000) version FA01. For the most part, we expect our review to be valid for the other sizes.

If someone comes across a different type of panel or if their Samsung KU7000 doesn't correspond to our review, let us know and we will update the review.

Update 01/16/2017: The 43" has a AA01 panel, so our review might not correspond exactly to that size.

Bottom right: Samsung KS8000 (UN55KS8000).  Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

The Samsung KU7000 is hard to recommend when cheaper TVs offer similar performances with a better value.

Samsung KS8000
49" 55" 60" 65"

The Samsung KS8000 is a superior TV especially for watching movies and with HDR content. It fits the living room better too since it can get a lot brighter. The KS8000 is pricier but is the TV to get for anyone looking at an upgrade over the KU7000.

Vizio P Series 2016
50" 55" 65" 75"

The Vizio P 2016 is better for movies, HDR and video games. Sports is also very good on it but it has a little worse uniformity.

Samsung KU6300
40" 43" 50" 55" 60" 65" 70"

The Samsung KU6300 offers nearly identical picture quality for SDR content, although it is not as thin. The Samsung KU7000 does provide slightly better HDR performance due to the wide color gamut, but for most people the Samsung KU6300 presents better value.

Sony X850D
55" 65" 75" 85"

The Sony X850D has a better picture quality when viewed from the side but not as good when watched directly from front or in a dark room. Get the X850D if most of the viewing is done in a well lit room.

Conclusion
SEE PRICE
Amazon.com

The Samsung KU7000 is a decent TV with a few flaws. It is good for playing video games and sports fans won't complain but movie lovers might be bothered by the small amount of judder and the limited HDR performance. When viewed from the side, the picture of the KU7000 also deteriorates. In the end, the Samsung KU7000 is not easy to recommend since the KU6300 is cheaper and has the same picture quality. If you were looking for an improvement, go with the KS8000 instead.
