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.

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.
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 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 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.
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.
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 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.
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.
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.
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.
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.
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.
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.
Even if it comes at a premium, the KS9000 still has ads on the home screen.
