Our Verdict
Feature-wise, the Samsung JS7000 is simply a JU6500 but with a wider color gamut. The picture quality is completely different, though. It has less motion blur and a better viewing angle, but worse contrast and uniformity.
- Great color accuracy at an angle
- Low input lag and motion blur
- Wider color gamut
- No 24p support, which means judder is present while movies are playing.
- Poor contrast ratio
- Poor uniformity

Differences Between Sizes And Variants
We reviewed the 55" Samsung UN55JS7000 (panel version: EH01). It has a PLS LCD panel (a sub category of the IPS family), which is why it has poor contrast and good viewing angle. It is the second Samsung that we reviewed with such panel, the first one being the smaller UN32J4000.
The 50" and 60" models use VA panels and are expected to have better contrast ratios and worse viewing angles.
We buy and test dozens of TVs yearly, taking an objective, data-driven approach to deliver results you can trust. Our testing process is complex, with hundreds of individual tests that take over a week to complete. Most of our tests are done with specially designed test patterns that mimic real content, but we also use the same sources you have at home to ensure our results match the real-world experience. We use two main tools for our testing: a Colorimetry Research CR-100 colorimeter and a CR-250 spectroradiometer.
Test Results
The Samsung JS7000 looks like a mid-range TV. The TV is fairly thin, and the bezel is small.
It wobbles quite a bit, and is made out of plastic.
The contrast ratio is really poor on this TV. It has an IPS panel, and produces gray blacks. Note that the 50" and 60" models don't have IPS panels and would have better contrast.
It is advertised as a full array backlight, but the 'Smart LED' feature is not even in the menu, so it is a probably an error on Samsung's website.
While it doesn't have a lot of DSE, the overall uniformity of solid colors is quite poor. The edges and corners are significantly darker, and you can see a few vertical bands.
The advantage of LCD TVs with a poor contrast ratio like this one is the color accuracy at an angle, which is great. The 50" and 60" models use VA panels and have narrower viewing angle.
Update 01/06/2017: We have changed the methodology of testing. Since this is an old TV which we don't have anymore, we extrapolated the results from 2016 TVs.
Due to the poor blacks, the uniformity in dark scenes is not good. The corners are brighter than the center of the screen.
In movie mode, the calibration of the picture was far off by default.
After calibration, the colors are a good deal better.
When you set 'Colorspace' to 'Native', the coverage of the Rec.2020 increases.
Its semi-gloss screen finish doesn't reflect a lot of light.
The JS7000 can get bright enough for any type of room.
The motion blur of the JS7000 is great. It has a little bit of overshoot, but overall, it is one of the best LED TVs in terms of minimal motion blur.
It doesn't support 24p, so it has the 3:2 pulldown judder in movies. This is a small and consistent judder, so most people don't see it.
The input lag is low when turning on 'Game Mode' under 'System' - 'General'. In conjunction with the low motion blur, it is a great gaming TV.
For 4k @ 60Hz @ 4:4:4, turn on PC mode as well as UHD Color.
The low-end cut off and loudness are decent for a TV. The frequency response is OK, but gets worse under load. Pumping may be present at higher volumes.
Very good distortion levels under low volumes. Slight increase under maximum load.
