Curved : Yes

The Samsung JS9000 is pretty eye-catching, thanks to its curved screen and gray back, and its stand is nice and stable. The bezel is not the thinnest, though.

While this TV did outperform all the others this year, the Sansungs JS8500 is a similar option that comes for a good deal cheaper. You pay a lot for a curved screen, so if that's not a 'must' for you, consider saving money with a flat TV.


Dimensions for 55" TV stand: 35.5" by 13.5".

Borders : 0.75" (1.9 cm)

Max Thickness : 2.83" (7.2 cm)


Picture Quality

This is a pretty good TV for watching Movies and regular shows. The blacks aren't the darkest, but they're dark enough to get the job done. The uniformity is really good, though. We hardly had any cloudiness when watching dark scenes, which is great.

The HDR, 3D, and motion smoothing features are nice extras, too, for those who are looking for them.

8.2 Contrast
Native Contrast
3695 : 1

The native contrast ratio of this TV is good. Turning on 'Smart LED' doesn't change the measurement on our checkboard pattern.

3.5 Local Dimming
Local Dimming

The edge-lit local dimming's zones are big, because the LEDs are located on the left and right sides of the TV.

6.7 SDR Peak Brightness
SDR Peak 2% Window
449 cd/m2
SDR Peak 50% Window
347 cd/m2

The maximum luminosity of a 2% white window is not really impressive, even with 'Smart LED' set to 'High'.

7.8 Gray Uniformity
50% Std. Dev.
2.638 %
50% DSE
0.158 %

As with the JS8500, the JS9000's edge-lighting backlight is really great at getting rid of the dirty screen effect (small darker patches). The top and bottom center edges are slightly darker, but it shouldn't be an issue.

4.2 Viewing Angle
LCD Type
Color Shift
20 °
30 °
Black Level
16 °

The picture quality when you view at an angle is not as great as what you get from directly in front.

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.

9.3 Black Uniformity
Native Std. Dev.
0.792 %

It has a few clouding spots, but nothing major. If you get one with major black uniformity issues, don't forget to apply slight pressure and massage the area with a dry cloth, and then let the TV sit for a few days. This often solves uniformity issues.

Movie mode has a good preset in terms of white balance and colors.

Achieving a great calibration was easy on this TV. See the third page of our review for the full settings.

8.0 480p Input

DVDs and SD channels looks as good as they can on this TV.

8.0 720p Input

Cable TV also looks good once upscaled.

9.0 1080p Input

As with all Samsung TVs, the 1080p upscaling doesn't produce a soft picture.

10 4k Input

4k Material looks great on this TV.

Like all Samsung JS series TVs, setting the colorspace to 'Native' increases the color gamut. For normal content, we don't recommend this, because it will produce over-saturated colors.

9.0 Reflections
0.7 %
Screen Finish

Samsung's glossy finish is great at reducing the ambient reflections, and thus increasing the perceived contrast ratio when you have a few lights on. There is a little bit of rainbow glare around bright objects.
This TV can get very bright, but its glossy screen finish won't be ideal if you have windows directly opposite the TV. Your eyes will tend to focus on those outlines.

9.0 3D
3D Type

The 3D is good, with no major crosstalk.



This is a really good TV for sports. There's not much blur, so fast movement will look crisp.

It also has few of the smudgy, dirty-looking patches of discoloration you see in pretty much every LED TV. That's a pretty big deal, considering it's usually in the quick pans of sports filming that you see this sort of defect.

9.1 Motion Blur

It handles fast motion really well, thanks to its very fast response time.

7.1 24p Playback
Judder-free 24p
Judder-free 24p via 60p
Judder-free 24p via 60i

Movies don't have judder when using a 24p source (like a Blu-ray player). However, it doesn't always do the reverse 3:2 pulldown, so you might see a little bit of judder in movies when watching over a 60p or 60i source (like on cable, or some streaming boxes). Of course, turning on 'Auto Motion Plus' solves this, but it adds the soap opera effect.

The JS9000 is a great gaming TV. It hardly has any blur, so even the fastest-paced games are going to look their best. There's also hardly any delay between when you do something in a game and when it appears onscreen, so there won't be much getting in the way when you need to react quickly.

The Samsung JS8500, which is the flat-screen equivalent of the JS9000, has noticeably higher input lag. If you're looking for a high-end TV for gaming, you should opt for the JS9000.

7.5 Input Lag
1080p @ 60Hz
23.6 ms
1080p With Interpolation
131.6 ms
1080p @ 60Hz Outside Game Mode
139.1 ms
1080p @ 60Hz @ 4:4:4
55.8 ms

In game mode, the input lag is very low (23.6 ms). In PC mode, the lag is a bit higher, at 55.8 ms.

8.0 Supported Resolutions
1080p @ 60Hz @ 4:4:4
1080p @ 120Hz
4k @ 30Hz @ 4:4:4
4k @ 60Hz
4k @ 60Hz @ 4:4:4

It doesn't support an input of 1080p @ 120fps, but handles 4k @ 60 Hz @ 4:4:4 well. For 4:4:4, turn on UHD Color and use PC mode.

Sound Quality

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.

6.9 Frequency Response
Std. Dev. @ 70
5.20 dB SPL
Std. Dev. @ 80
5.52 dB SPL
Std. Dev. @ Max
7.33 dB SPL
92.6 dB SPL
Low-end Cutoff
63 Hz

The loudness and low-end cut off are very good for a TV, but the frequency response is poor. There seems to be pumping present at higher volumes.

5.6 Total Harmonic Distortion
Distortion @ 70
Distortion @ 80
Distortion @ Max

The distortion isn't bad at 75 dB SPL. At higher volumes the distortion increases to noticeable amounts, but not as much as some other TVs.


Smart Features

Smart OS : Tizen

The remote is really good. It would be better if it came with more buttons - you have to use an onscreen keypad to input channels - but the motion and voice features are great ways to navigate quickly. The smart platform itself is likewise really good.

The One Connect box houses the processor and the inputs. Your TV won't be usable if it is not connected, and it's an unfortunate extra bit of clutter. Having this separate does mean, though, that you'll be able to upgrade some of the TV's 'guts' in the future, should you wish to do so.

Remote : Smart

The included Bluetooth smart remote is great for using the smart features. However, there is no number pad present directly on it, which makes switching channels a bit more cumbersome.

Power Consumption : 101 W
Power Consumption (Max) : 206 W

7.9 Mixed Usage

The Samsung JS9000 is our overall top rated TV this year. It has picture quality very similar to the cheaper JS8500, which is really great both in a dark and bright room. It outranked the JS8500 in our test suite, thanks to the lower input lag. If you don't care about the input lag, the curve, or the full OneConnect box, you get the same excellent picture quality with the cheaper JS8500.
