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.
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.
This is a great TV for movies. The blacks are pretty deep, and the uniformity is good, too.
If you're only interested in watching TV and movies in a dark room, an even better choice is the Sony X850C.
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.
The colorspace set to 'Native' has a color gamut coverage of 55.5978%. The default 'Auto' has 55.4258%. If you want a wider color gamut, go for the pricier JS8500.
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.
This is quite a good TV for watching sports. It has little blur on fast movement, which is ideal for watching athletes taking off at full tilt across the screen.
It has a bit more of the smudginess on the screen than you get with higher-end TVs like the JS8500 and JS9000, but it's still better than most of the TVs we tested this year. You'll have no issues watching sports on this TV.
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.
The minimal blur is also really important for gaming. Fast movement should look good and crisp on this TV, so you'll be all set to enjoy your favorite games.
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.
For a TV, the JU7100 has decent bass. It can also get pretty loud, though the louder the TV gets, the more distorted the sound.
The sound isn't all that accurate, so if you're looking for a good audio experience to go along with the really good picture quality you get with this TV, you should consider getting a separate speaker system.
Note: Sound Quality test for TVs reviewed before 2017 was performed at 75dB, 85dB, and Max SPL. Starting 2017, the target SPL levels have been changed to 70dB, 80dB, and Max dB SPL.
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.
