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.

Our Verdict

8.2 Mixed Usage

Great TV for a range of usage. Picture quality is excellent and fast motion is well defined. Blacks can get very deep. Extremely bright highlights and deals with reflections well.

Test Results

Design
Design
Stand

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.

Design
Back
Wall Mount VESA 400x400

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.

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.

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.

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.

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.

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.

Differences between Sizes and Variants

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.

Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

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 were tested on different test benches, and the results aren't 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.
