Type : LED
Resolution : 4k
Refresh Rate : 120 Hz

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.

Design

Curved : No

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. 

Stand

The stand of the TV has a nice chrome finish. It has a fairly large footprint and goes a long way toward the back of the TV. It could not be ideal if you want the TV to lay against a wall.

Footprint of the 55" TV stand: 33.9" x 15"

Back
Wall Mount : VESA 400x400

Even the back of the TV is both sleek and attractive with its textured finish. A cover that is included with the TV hides the back inputs that won't be in the way to wall mount the TV.

Borders
Borders : 0.39" (1 cm)

The borders of the TV are thin and have a nice metal polish to them.

It is reported that the 75" variant of this TV has thicker borders.

Thickness
Max Thickness : 1" (2.6 cm)

Very thin from a 90 degree angle. The bottom part of the TV is thicker. The maximum thickness measurement include the horizontal metal looking plastic border that goes across the back of the TV.

8.2

Picture Quality

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.

9.3 Contrast
Native Contrast
:
6820 : 1

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.

3.5 Local Dimming
Local Dimming
:
Yes
Backlight
:
Edge

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.

Motion

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.

8.1 Motion Blur

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.

Inputs

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.

4k @ 60Hz @ 4:4:4 + 8 bit HDR

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').

Sound Quality

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.

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.

Low-end Cutoff

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.

4.5 Total Harmonic Distortion
Distortion @ 70
:
0.057
Distortion @ 80

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.

Smart Features

Smart OS : Tizen (2016)

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.

Apps

YouTube, Netflix and other popular apps are available and menu navigation is straightforward. As a whole, the smart platform presentation is neat compared to what Samsung had to offer in 2015.

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

TV Controls

A button that offers basic TV controls such as changing inputs, volume and turning the TV on and off, is located underneath the Samsung logo on the front of the TV. It can be accessed when the TV is wall mounted.

Remote
Remote : Smart

For the most part, the minimal remote is sufficient but at times can be hard to use in the dark since not all buttons have tactile feedback. It also doesn't work as a pointer which can make text input a little awkward.

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

Top left: Sony X930D (XBR55X930D). Top middle: Samsung KS9000 (UN55KS9000). Top right: Vizio P Series 2016 (P65-C1). Bottom left: Samsung KS9500 (UN55KS9500). Bottom right: Samsung KS8000 (UN55KS8000). Unlike our other photographs, this picture wasn't taken under a controlled environment, so do not draw conclusions from it.

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.

8.2 Mixed Usage

Great for any usage. Excellent picture quality. Handles motion well and suitable for a dark or bright room. Great HDR performance. Unfortunately the picture quality degrades from the side.

8.2 Movies

Great for watching movies. Dark scenes appear rich and well defined. Smooth playback from any source.

8.1 TV Shows

Great for watching TV in a bright room. Deals with reflections well and displays a range of resolutions clearly. Very bright to deal with ambient light. Unfortunately the great picture quality diminishes when viewed from the side.

7.9 Sports

Very good for sports. Handles fast motion very well. Uniform screen results in quality playing field.

8.4 Video Games

Excels for video games. Very little input lag which is good. Fast motion remains well defined. Great picture quality.

8.4 HDR Movies

Impressive HDR performance. Deep blacks and rich colors. Very bright highlights on top of an excellent picture quality.

7.3 PC Monitor

Great PC monitor. Handles a wide range of resolutions well. Displays text clearly on all backgrounds. Feels very responsive with little motion blur.
