The 4k Samsung KS8000 LED is a well rounded UHD TV that delivers a great picture quality. However, its picture deteriorates at an angle. From the front, everything looks colorful and detailed. It handled motion well and input lag was especially low. The KS8000 can also get very bright and does justice to HDR content. The equivalent model in Europe is the KS7000.
The look of the Samsung KS8000 is particularly good. Its design is simple yet high-end. From the chrome finish to its glossy back, this TV leaves an impression. When viewed directly from the side, its thinnest is striking. Its shiny stand also look good but its footprint is a little wide.
The stand of the Samsung KS8000 is simple and boast a chrome metallic finish. Assembly for these two stands were just a one step job, needing no screws or tools.
Footprint of the 55" TV stand: 44.1" x 9.1"
On the 65" TV, an alternate middle position can be used for the stands where the two feet are about 39" apart.
On the 60" TV, an alternate middle position can also be use for the stand.
The Samsung KS8000 has a black reflecting plastic backing, that is prone to both dust and scratches.
Remove the plastic stoppers to expose the mounting points. Bolt sleeves are included in the box for mounting.
The back panel of the TV is attached by glue, which is reported by some readers to become unstuck over time. This does not affect the picture quality of the TV.
Picture quality is excellent on the Samsung KS8000. Even in a pitch black room, dark scenes appear richly detailed. In more colorful material like cartoons, the color pops and can get very saturated. The same can be said for HDR content which impresses. The KS8000 does a good job with low quality content too like for standard cable TV and DVDs. Deals very well with reflections and can get bright to suit even the brightest room.
Very deep blacks and remarkable native contrast ratio results in a rich picture quality. The contrast is very similar to the Samsung KS9500.
The Samsung KS8000 wasn't able to brighten the little dot in our video that much. When local dimming is activated, it produces blooming around bright highlights, on a big vertical column. Still, for regular movie watching and especially HDR content, local dimming ('Smart LED') is worth it for the deeper blacks it produce and the very bright highlights. Blooming is more noticeable at an angle.
The KS8000 has a very good SDR peak brightness. It is a bit less bright than when in HDR mode, but it is still one of the brightest TV tested in 2016.
Like for other TVs, we use the local dimming setting ('Smart LED') that brighten the 2% window the most, in that case 'High'. The peak brightness of small highlights is very high at 1472 cd/m². On a static image, the maximum brightness drops to around 500 cd/m². For the best HDR experience, leave 'Smart LED' to 'High'.
Update: Updated with sustained brightness and remeasured the peak brightness (which is now even closer to the KS9000).
The left and right edges of the screen are darker and the top and bottom edges are slightly brighter. That said, there is no obvious banding problems which result in a minimum of the 'dirty screen effect' (DSE). Compared to most TVs, this is good.
Viewing angle is a notable downside of this TV but we have seen worse. Still, from an angle, the blacks aren't as deep and the colors change.
While displaying a completely black picture, the KS8000 doesn't exhibit any obvious issues. Some very faint clouding spots but as a whole the screen looks uniform.
Very smooth color gradations. Very minor inconsistencies in reds prevent the Samsung KS8000 from getting a perfect score. In regular content though, this won't be noticeable.
Very low dE for out of the box which is excellent. Some TVs can't even get at that level after calibration.
Near perfect post calibration results. As with other Samsung TVs, calibration was easy to achieve. Both white balance and color has very low dE. Gamma sit correctly at 2.2. Our calibration settings can be found here.
Good color coverage as a whole. Colors can get very rich under HDR materials.
The Samsung KS8000 is one of the 2016 top performers in color volume and produces very saturated colors at high luminosity levels. Unfortunately, at low luminosity levels the colors can't get very saturated.
Like many other VA TVs, the Samsung KS8000 does not present any image retention at all. Even right after the 10 minutes burn-in scene, no faint image can be seen from any of the colored logos. This is a very good result and should please any gamers of PC users.
Very faint reflections. The picture can still be seen through reflections which is great. The TV can get bright enough to fit in any room, even the brightest.
Motion looks good on the Samsung KS8000. There isn't much motion blur thanks to the good response time. Movies play smoothly over any source and content can be interpolated up to the panel's native refresh rate of 120Hz.
This isn't the fastest response time we've seen but it won't be a problem in most cases. The trail behind our logo has an average length but is faint enough not to be an issue in regular content.
The KS8000 uses PWM to dim the backlight, which results in some duplications following the logo. It is possible to reduce the flicker frequency to 60Hz which helps to clear up motion, but this isn't possible when in the 'Game' special viewing mode.
24p sources is always judder-free no matter the TV settings. To remove judder from 60p and 60i sources, set 'Auto Motion Plus' to 'Custom' and both sliders to 0. This won't add the soap opera effect (SOE).
Since this TV is 120Hz, 'Auto Motion Plus' can be used on 30Hz and 60Hz signals. This will add the soap opera effect (SOE). Low custom values will work well to smooth out motion with a minimum of the soap opera effect.
Very responsive to input on the Samsung KS8000. Input lag is great for even the most serious gamers. Those who want to use the TV as a PC monitor will also like the multiple inputs and resolutions it supports and the fact that the screen can get very sharp with the good settings.
Great, even for competitive gaming. Not to say that this TV will make anyone's skills improve but those who like to have every little advantages on their side will enjoy that low of an input lag. The overall experience feels very responsive even for the games that requires very fast reflexes. To get that low input lag, 'Game' mode has to be enabled. When sending and HDR signal under game mode at an 1080p resolution, the input lag is 22.6ms.
Update 04/21/2017: Some users are reporting a bug with game mode which causes an infrequent and temporary (1-2 seconds) separation of colors.
Most of the tested inputs works except for 120Hz. To ge 4k @ 60Hz @ 4:4:4, 'HDMI UHD Color' has to be enabled from the picture menu. For other resolution, labeling the HDMI input to 'PC' will do the trick. Input lag in PC mode is 37.8 ms.
The TV supports 5.1 passthrough for Dolby Digital and DTS, but it is necessary to select the correct audio type in the sound settings, since it doesn't change automatically.
The sound on the Samsung KS8000 is not too bad but most basic sound bars or home theater setups will complement the TV much better. In some minimal setups though, like for in a bedroom, it gets the job done without any additional wire clutters.
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.
Decent frequency response, especially for a TV. The low-end cutoff of 85Hz and maximum loudness of 92dB are good. However, there will be noticeable pumping and compression under heavy load.
Subpar results. The overall amount of harmonic distortion is rather high, but at the same time, there is not a big jump at higher SPLs and distortion remains relatively constant.
The Samsung KS8000 smart platform isn't the best but offers a good experience. Navigating through the different menus and launching apps feels responsive. Most popular apps are available.
When a new device is detected (such as when a computer is woken from sleep while plugged into an HDMI port) the TV automatically switches to this device. This may be an annoyance if you are watching other content at the time.
Unfortunately, there are ads on this TV. There is also no way to completely disable them.
We tested the 55" (UN55KS8000) version FA01. It is also available with version AA02. For the most part, we expect our review to be valid for the other sizes.
We've received a report that the 60" (UN60KS8000) has version EA01, with a narrower viewing angle. The 60" also has a different bezel that is thicker.
We also receive information about the 65" model (UN65KS8000), it seem there is also the version FA01 and AA02.
If someone comes across a different type of panel or if their Samsung KS8000 doesn't correspond to our review, let us know and we will update the review.
The Samsung KS8000 is the best buy for a TV in this price range if you want to use it for multiple usage. Not a lot of other TVs can compete with its high picture quality, number of features and asking price. See our recommendations for the best flat screen TVs and the best smart TVs.
These two TVs have been tested on different test benches, and the results are not directly comparable. The Samsung NU8000 is a much newer TV that supports some of the latest gaming features like FreeSync VRR and low input lag with motion interpolation. The Samsung KS8000 has a higher contrast ratio and can deliver deep blacks to improve dark room performance. The two TVs have a similar picture quality and can get similarly bright. Both have a wide color gamut, so HDR content looks equally good.
