The Samsung JU6700 4k LED TV has the same picture quality as the cheaper JU6500, but the screen is curved and it comes with a better remote. It's a good UHD TV, but it has a few flaws.
The Samsung JU6700 UHD TV looks very similar to the JU6500. The borders are slim, and it feels like a mid-range TV.
The stand is similar to that of the pricier JU7100, but curved.
The Samsung JU6700 isn't the best TV for watching movies. It does have pretty deep, fairly uniform blacks, but since it has judder, 24 fps movies will look pretty bad.
You also don't get more advanced features you see in pricier 4k TVs, things like HDR, local dimming, and the ability to play 3D material.
The contrast ratio is good, but nothing spectacular.
There is a significant amount of deviation in the gray uniformity, and a considerable amount of DSE, too.
This TV doesn't maintain its colors well when viewed at an angle. The curve of the screen exacerbates this issue, because the side nearer to you is at a greater angler than it would be on a flat screen.
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.
Our unit had a few brighter spots near the bottom edge of the screen, but they weren't noticeable with normal content.
Its semi-gloss finish doesn't reflect much, but because its screen is curved, anything that is directly in front gets magnified.
The JU6700 can get bright enough for pretty much any room.
This is a pretty good TV for sports fans. There's not much blur, so moving objects won't look streaky, and while there is some noticeable patchiness to the look of sports, it's far from the worst TV we've seen for that.
The motion handling could be better on this TV. It has a bit more blur than average, although you won't really notice it unless you are gaming or watching sports.
Like the JU6500, there is a small constant judder when watching movies. You can get rid of it by turning on 'Auto Motion Plus', but it adds the soap opera effect.
There's no noticeable delay between when you make an action in a game and when you see the reaction onscreen. That, plus the good motion handling, makes this a good curved option for gamers. If you don't watch movies, there's not much reason to pay extra for the Samsung JU7500.
In game mode, the input lag is low. PC mode (for 4:4:4 support), is a bit higher, at 44.2ms.
To enable chroma 4:4:4 at 60Hz, turn on 'UHD Color'.
The sound is reasonably accurate at regular listening volumes, but gets pretty distorted when you crank it up.
The TV can get pretty loud, which is good, and the bass, while not great, is decent for a TV.
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.
Pumping may be present under heavy load. The frequency response is decent at lower volumes. The bass cut-off is not bad for a TV and it gets relatively loud.
There is a slight but noticeable increase in distortion at higher volumes, but decent distortion at comfortable listening levels.
The app selection on Samsung's new Tizen OS is better than it was at the start of the year, and it comes with a full web browser. Overall, a good smart platform.
Contrary to the JU6500, the JU6700 comes with a fancy smart remote, which is great for browsing the web.
