The Samsung JU7100 is a great 4k LED TV. With the exception of the discoloration it gets when viewed at an angle, it has impressive picture quality. It is also a great gaming TV, with low input lag and minimal motion blur.

Our Verdict

7.6 Mixed Usage

The Samsung JU7100 has great picture quality, assuming you don't sit at an angle. It is better than last year's Samsung 4k TVs for gaming, thanks to the lower input lag. Upscaling works better than the competition, so you don't need to worry about 1080p content looking soft on this TV.

Pros
  • Great gaming TV. Very low input lag and minimal motion blur.
  • Great picture quality in both dark and bright rooms.
Cons
  • Loss of color saturation at an angle.

The bezel looks great on the Samsung JU7100, but the borders are slightly thicker than most 2014 models. They also slant towards the screen a little bit.

The stand is very stable, but it doesn't swivel.

Contrast

The contrast ratio is average. It's a little bit sub-par when compared to some other VA panels, but unless they are side to side, you won't really notice the difference between blacks of 0.032 cd/m2 and 0.020 cd/m2.

The local dimming feature is not effective. In this video, 'Smart LED' was set to high. You can see that the backlight adjusts for the moving dot, but it affects only about 50% of the screen at a time.

All Samsung TVs lose color saturation when viewed at an angle. You can still see the picture, but it is nowhere near as good as when seen from directly in-axis.

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.

480p Input

For lower resolutions like DVDs, 'Digital Clean View' set to high does a great job of reducing compression artifacts and increasing the amount of detail, without softening the picture.

Cable TV can also benefit from turning on 'Digital Clean View'.

1080p Input

Upscaled 1080p looks nearly as sharp as with native 1080p, which is great. In comparison, the Vizio P 2015 looks a lot softer/blurrier.

Screen Finish
Glossy

The Samsung JU7100 reflects very little ambient light due to its glossy screen, which is great for improving the perceived contrast ratio when a few lights are on. However, this type of finish has two downsides: direct light sources (like bulbs) get a rainbow around their reflection, and the eye tends to focus instead on reflected objects because they are well-defined. Therefore, this TV is ideal when you have the lights either overhead or behind the TV - not facing the TV.
It can get bright enough for a bright room. You're able to see the picture even through the reflection of the window we use for tests.

Movies don't have any judder when you are watching via a Blu-ray player at 24p. Via 60p or 60i though (like when playing on a PC computer), it can't reliably do the reverse 3:2 pulldown. You can turn on 'Auto Motion Plus' to fix it, but at the cost of the soap opera effect.

4k @ 60 fps worked at chroma 4:4:4. You need to turn on 'UHD Color' and also set the input to PC. If it doesn't work for you, try changing your cable. It didn't work with our Monoprice 18 Gbps 15ft Redmere cable, but it worked with a cheap 3 ft one.

Smart OS Tizen

The included smart features work really well. The app selection is pretty good, and the remote has the handy motion and voice control features, so navigation and search are pretty smooth.

The HDMI inputs are all on the OneConnect Mini box, which may not be ideal for mounting purposes. The included cable that is used to connect the box to the TV is 7' long.
