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 limited, judder is present in movies and the picture deteriorates when viewed from the side.

  • Good TV for playing video games
  • Better than average uniformity
  • Picture deteriorates when viewed from the side
  • HDR performance is limited
  • Judder is present in movies

Samsung KU7000 Design

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 Movies

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 but it doesn’t look any better than standard content. The colors are quite good out of the box, and the TV looks clear when displaying content from DVDs to 4k video.

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.

Sound is average on the Samsung KU7000 which isn’t too bad for a TV. Most sound bars would be an upgrade but those that don’t want the additional clutter should still be somewhat satisfied by the sound of the KU7000.

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.

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

CHECK PRICE
Right

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.

8.2

Vizio P Series 2016

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.

7.2

Samsung KU6300

40″ 43″ 50″ 55″ 60″ 65″ 70″

Amazon

CHECK PRICE
Right

The Samsung KU6300 offers nearly identical picture quality although it is not as thin. Since it is sold for less, it represents a better value and is the TV to get over the KU7000 for most people.

7.6

Sony X850D

55″ 65″ 75″ 85″

Amazon

CHECK PRICE
Right

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

Amazon

CHECK PRICE
Right

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.
