Samsung KU7000
TV REVIEW
This tv was replaced by the Samsung MU7000
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.

Score components:
Subjectively assigned
Score distribution:
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.

Score distribution:
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:
- 100% Native Contrast
Score distribution:
Native Contrast
:
4514 : 1
What it is:
Ratio of the white brightness divided by the blacks measured on our checkerboard test pattern with a white target of 100 cd/m².
When it matters:
Dark scenes in a dark room.
Good value:
> 3,000
Noticeable difference:

Score distribution:
The contrast ratio of this TV provides good dark scene performance and should not be an issue for most viewers.
0
Local Dimming
What it is:
The lights behind the LCD layer adapt to the picture displayed, improving the contrast ratio.
When it matters:
Dark scenes viewed in a dark room.
Score components:
Subjectively assigned
Score distribution:
Local Dimming
:
No
What it is:
Whether it has a feature that controls the LEDs behind the LCD layer, to match the picture and darkens the dark portion of it.
When it matters:
On LED TVs only. Dark scenes viewed in a dark room.
Backlight
:
Edge
What it is:
Configuration of the lights of the backlight.
When it matters:
Effectiveness of the local dimming.
Good value:
Full-array/direct lighting is better for local dimming. As for the uniformity of the screen, it depends on the implementation. Some edge-lit TVs have more uniform blacks than some full-array TVs.
There is no local dimming on the KU7000. For reference, we took a video of our test. The backlight is edge lit, unlike the KU6300 which has a direct backlight.

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.

:
VA
What it is:
Type of LCD technology used by the TV.
When it matters:
Different technologies have different viewing angle properties.
Good value:
IPS maintains good color accuracy at an angle, but has a poor contrast ratio from in front. VA has great picture quality in front, but loses saturation at an angle.
Color Shift
:
35 °
What it is:
Angle where the colors noticeable shift compared to when viewed from directly in front of the TV. 0 ° means directly facing the TV. Measurements are up to a maximum of 75 °.

The viewing angle is quite good for a VA TV, and should not be an issue for most people. Color saturation is lost when viewed at an angle however the picture remains more defined than most other VA TVs.

Good value:

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.
Score distribution:
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.

What it is:

When it matters:

:
10 Bit
What it is:
Number of bits per pixel to represent a specific color. Note: we consider 8-bit with dithering to be equivalent to 10-bit, as long as the 10-bit gradient looks smooth.
When it matters:
HDR content like UHD Blu-ray players. Won't matter for cable TV, regular Blu-ray movies, video game consoles or content displayed from a Windows PC. Those are limited to 8-bit color.
Good value:
10-bit.
Noticeable difference:
1 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.

Watching sports on the Samsung KU7000 is pretty decent. Fast moving objects such as a football being thrown from a player will be followed by a faint trail and some screen uniformity issues may be visible during panning shots over a game field, but this should not be an issue for most people.

Smart Features
Score components:
Subjectively assigned
Score distribution:
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.

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.

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

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.
