The Samsung KS9000 4k UHD LED TV has a lot to offer. The picture quality is excellent and it handles most content nicely. With the fact it can get very bright and doesn't have much reflections, it is also a good fit for even the brightest living room. Unfortunately, it isn't perfect. Its picture quality diminishes when viewed from the side.
- Great TV for watching movies and HDR content.
- Very low input lag which is great for playing video games.
- Very bright and not much reflections.
- Picture quality deteriorates when viewed from the side.
The Samsung KS9000 pleases the eyes with its high end look and thinness. The materials it's made of all seems to be of high quality. From its chrome stand to its thin metal borders and even its textured back, this TV is sure to look great in any room. It has the same overall look as the Samsung KS9500 minus the curved screen.

The Samsung KS9000 provides excellent picture quality. Colors really pop, details are plentiful and highlights are very bright. This stay true whatever the sources, even for low quality content like cable TV and DVDs. It gets even better on high quality content like blu-rays and 4k materials. The KS9000 is able to produce beautiful scenery even on very dark content. It gets very bright and handles reflections well.
Impressive black level and very high native contrast ratio. This result in a picture that pop in most content, even on dark scenes. Top and bottom black bars in movies nearly doesn't emit light which is good.
Very faint clouding spots that won't ruin even the darkest scenes. Good black uniformity performance.
The local dimming feature on the KS9000 doesn't work very well. It does darken the blacks but some small highlights too like the dot in our test video. Although it isn't that much apparent in the video, local dimming sometimes creates big vertical blooming areas on big highlights depending on the scenes. It is more noticeable in person. For this test, we set local dimming ('Smart LED') to 'High'. A TV with a full array backlight can produce much better results.
Very impressive and similar results to the Samsung KS9500. Highlights can get extremely bright and as a whole the screen can also maintain a high level of brightness. As the KS9500, brightness vary on a static screen but is not a problem on regular content. On the downside, very bright highlights can create big blooming areas. We used local dimming ('Smart LED') set to 'High' to get as high peak brightness.
Update: Updated with sustained brightness.
The KS9000, like the curve KS9500 has a good SDR peak brightness performance and is, whit the rest of the KS Series, one of the brightest TV of 2016. Unlike other TV that is less bright when outside of HDR mode, the KS9000 is almost as bright when watching standard content like TV shows.
The left and right edges are darker and top and bottom brighter. Compared to most LED TVs, the gray uniformity on the Samsung KS9000 isn't a big issue with no obvious banding problem occurring on camera pans over playing fields of uniform color.
At an angle, colors shift and blacks appear less deep. This is a common issue for LED TVs of this type (VA) but we have seen worse viewing angle.
Very low white balance and color dE which results in an excellent out of the box state.
Like other Samsung TVs, calibration went smoothly and helped reduce both white balance and color dE to a very low level.
Good coverage of colors in DCI P3 and fair score for the Rec 2020 colorspace. This TV is able to produce very deep colors and HDR content benefit from this.
The KS9000 has a similar color volume to Samsung's top 2016 models. It can produce very bright saturated colors but performs worse than some other TVs in dark scenes.
Nearly perfect gradient. Some very minor irregularities in the darker red band but nothing that can be seen in regular content. Fine level of colors overall.
The screen of the KS9000 does reflect lights but less than most other TVs. Even in a bright room the picture of the KS9000 stays visible.
Good motion performance on the Samsung KS9000. Blur isn't a real issue even on fast action plays. Movies played from any source appear smooth. The KS9000 is able to interpolate content up to the native refresh rate of 120 Hz.
There are TVs with faster response time but there is no big issues with how the KS9000 handles motion. Not much blur can be seen in fast action scenes. In the picture, only a faint trail is following the moving logo.
No special settings needed to remove judder from 24p sources although to get the same result on 60i and 60p content, 'Auto Motion Plus' has to be set to 'Custom' with both sliders set to 0. This doesn't add the soap opera effect.
Motion Interpolation can be activated with the 'Auto Motion Plus' setting. This will work for all sources up to 60 fps.
The Samsung KS9000 supports a wide range of inputs. Action sent by controllers are near instantly displayed on the TV due to the low input lag. It supports a wide range of resolutions and displays text very clearly with chroma. It also has many HDMI inputs.
Very low 1080p input lag which is great. The responsiveness you get from controller inputs nearly can't be felt. Players that like first person shooter, racing or combat games will like gaming on the KS9000. Unfortunately, motion interpolation ('Auto Motion Plus') bring the input lag too high to consider using that option. When sending and HDR signal at 1080p resolution under game mode, the input lag is 22.6ms.
- 20% 1080p @ 60Hz @ 4:4:4
- 20% 1080p @ 120Hz
- 20% 4k @ 30Hz @ 4:4:4
- 20% 4k @ 60Hz
- 20% 4k @ 60Hz @ 4:4:4
Except for 1080p @ 120Hz, the KS9000 doesn't have problems with most PC inputs. To get 4k @ 60Hz @ 4:4:4, 'HDMI UHD Color' has to be turned on. For 4:4:4 in other resolutions, just edit the HDMI input to 'PC' (hover the current HDMI input used from the input list and press up on the remote, then 'Edit' and select 'PC').
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.
Compared to other TVs, the Samsung KS9000 doesn't sound too bad. Other external sound devices, like a sound bar, will still do much better though. Unless you are keen to a minimal setup, it is a good idea to invest into another external sound solution.
Good frequency response. The low-end cutoff and maximum loudness are decent, for a TV. However, at higher volumes, there is pumping and compression present.
Poor distortion results. Although there is no dramatic rise in distortion as the volume increases, but the overall level of distortion at all levels, is elevated.
Sporting the new Samsung 2016 smart platform, the Samsung KS9000 offer a good experience with most of the popular apps at the disposal. Menu navigation is straightforward although a remote with a pointer would have helped for text input. The KS9000 offers plenty of inputs, more than enough for most home setups.
Even if it comes at a premium, the KS9000 still has ads on the home screen.
Differences between Sizes and Variants
We tested the 55" (UN55KS9000) version FA01. For the most part, we expect our review to be valid for the 65" version (UN65KS9000) and 75" version (UN75KS9000). If someone comes across a different type of panel or if their Samsung KS9000 doesn't correspond to our review, let us know and we will update the review.
Compared to other TVs
The KS9000 is definitely the best overall LED TV we tested so far for a mixed usage. However, it is priced very high, so we don't really recommend it.
The Samsung KS8000 is a better buy. It is almost as good as the KS9000 on all aspect, it just doesn't get as bright. The price difference is not worth it, so buy the cheaper KS8000.
The Vizio P has a lot more bang for the buck for a similar picture quality, as long as the content being played is of high quality. For exclusively watching movies in the dark or playing video games, the Vizio P is a smarter buy. For other usage, like sports, cable TV and DVDs, you better buy the Samsung KS9000. In the living room, the Samsung KS9000 is also better.
The Sony X930D is worse for playing video games. For most other content, the Samsung KS9000 is also slightly better. Even more so when watched under a bright lighting environment or a very dark room. The Samsung KS9000 is a more versatile TV and a better buy.

Questions & Answers
That said, some other HDMI cables cannot support the full bandwidth they are advertised to, so some High Speed rated cables may not be able to carry video at 4K; they'll show a blank screen or a picture with obvious errors. We have had best results with the Amazon Basics HDMI cables here.
