The 4k Samsung MU9000 is a versatile TV, with very good picture quality and great motion handling. It can produce deep and uniform blacks, and supports HDR quite well. It isn't all good though as the image accuracy degrades at an angle and the range of colors produced isn't as wide as some other TVs.

Our Verdict

7.9 Mixed Usage

Great TV for a range of uses. Produces deep blacks, even in a well-lit room due to the excellent anti-reflection coating. Can get bright and product a wide range of colors. Motion handling is great, with only a short trail following fast objects. Unfortunately the image accuracy degrades when viewed at an angle.

Test Results

Curved No

The design of the MU9000 is great. The TV feels as premium as it looks, and has a few nice touches such as the thin borders and textured back. Most of the inputs are located on the OneConnect box and are easy to access.  


The stand of the MU9000 is similar to other Samsung TVs such as the KS9000 from 2016. It is small enough to fit on most tables and supports the TV well, although it will wobble a bit if knocked.

Footprint of the 55" TV stand: 33.7" x 13.8"

Wall Mount VESA 400x400

The rear of the TV looks good. Most of the inputs are located on the OneConnect box and are easy to access. The cable management is great, as the stand of the TV is used to route the cables out of the back (visible here).

Borders 0.39" (1.0 cm)

The borders of the TV are thin and look great.

Max Thickness 1.89" (4.8 cm)

The TV is quite thin when viewed from the side. The bottom half of the TV is the thickest part, but even then it won't stick out much if wall-mounted.

Maximum Temperature
100 °F (38 °C)
Average Temperature
90 °F (32 °C)

The TV stays fairly cool, only getting slightly warm to the touch in a few places on the back. The OneConnect box only gets slightly warm, reaching a maximum of 32 °C.

Build Quality

The build quality of the MU9000 is good. Some minor gaps are present around the frame, but overall the parts feel well constructed and very durable. There is some flex when pushing on the rear plastic, but this isn't an issue.

Native Contrast
6023 : 1
Contrast with local dimming
6027 : 1

The Samsung MU9000 has an excellent native contrast ratio just above 6000:1, which is great for people who have a dark home theater setup as it results in detailed dark scenes with deep blacks.

With the local dimming feature set to 'High', the contrast ratio remains almost the same, which shows the poor implementation of the local dimming on the MU9000.

Note that we could not completely turn off the local dimming feature on the MU9000, but simply set it to 'Low'.

Picture Quality
Local Dimming
Local Dimming

The local dimming feature on the Samsung MU9000 is bad and is very similar in performance as on the MU8000 and Q7F. Since the MU9000 is an edge-lit TV and that the local dimming span across a large vertical zone, a large vertical blooming is visible following the moving highlight on our test video. The local dimming has 3 setting ('Low', 'Standard' and 'High') and we recommend to test each setting to see what is best for you. If you find that the screen luminance change too much depending on the on-screen content, set the local dimming to 'Low' or 'Standard'.

Plot over time

Great SDR peak brightness. The sustained brightness remains a good 400 - 600 cd/m² for all tests, yet local dimming is able to spike the brightness above 1000 cd/m² in an ideal case, though not for very long, as shown in the plot over time. This brightness behavior is very similar to the MU8000, but the MU9000 is a little brighter in every test.

Plot over time

Decent HDR peak brightness. The real scene brightness is good, and the TV's local dimming can make highlights in dark scenes even brighter, as shown by our smaller window tests. The 'Dynamic' picture mode is even brighter than the 'Movie' mode we test, as seen in the plot over time, but has less accurate picture quality.

The gray uniformity of the MU9000 is good. The edges of the TV are a bit darker, but this isn't too noticeable with normal content. The uniformity of the middle of the screen is very good, so there is very little dirty screen effect when panning over uniform sports fields. The 5% uniformity look even better than the 5%, which is very good.

Bad viewing angle, but fairly typical for a VA panel. Blacks turn gray and colors degrade when the TV is viewed from a small angle, while brightness decreases at a larger angle. People viewing the TV from the side will not have as good picture quality as people viewing from the front.

The overall black uniformity of the MU9000 is decent. On the native black uniformity test picture, some clouding is visible in the center of the screen, but it is very faint. Unlike the 2016 TVs with local dimming such as the KS8000 or KS9000, the local dimming on this TV can't be turned off. Instead, the 'native' picture was taken with local dimming set to 'low' and some vertical blooming is visible because of the edge-lit backlight.

The black uniformity picture with local dimming was taken with the local dimming set to 'High' and the same clouding that was visible on the native test picture is still there, but it is less obvious.

The MU9000 is excellent at handling reflections. It has a glossy finish, so reflections are defined but also significantly reduced in intensity. There is a minor purple tint, but it works to further reduce any reflections. This is a great result, even for a bright room.

Prior to calibration, the accuracy of the MU9000 is very good. The target gamma of Samsung TVs is a bit different to our target of 2.2, but the colors are very accurate and the white balance is good in the 'Warm2' color temperature. For most people, a calibration is not necessary.

Good wide color gamut, though not as wide as the KS8000 from last year. The TV can produce fairly saturated red and blue, but struggles with saturated green, though this is common for modern TVs. The TV also isn't very accurate at showing the colors its able to. The MU8000 has better accuracy and a very similar color gamut.

The TV's EOTF in the 'Movie' picture mode we test follows the HDR PQ curve very well, up until where it clips at its peak brightness. The EOTFs in Game and PC mode here and here are also very accurate, but have less peak brightness than Movie mode because local dimming is not applied.

Mediocre color volume, though only really limited by its color gamut and dark color performance. The TV shows its wide color gamut almost perfectly throughout its entire brightness range except for really dark colors. The TV's poor local dimming was unable to make our black-with-white-border slide very dark in the center, so the black point, while still good, isn't as low as a TV with good local dimming like the Sony X900E.

As with other TVs of the 2017 MU line of Samsung, the MU9000 can display how gradient test image without any banding associated with an 8-bit panel. Overall the gradient looks smooth, but there is some imperfection, mostly in the darker green color. Luckily, we did not see any major banding while looking at some particularly demanding scene from HDR movies, which is great.

Response Time

100% Response Time

The response time of the MU9000 is very fast, resulting in only a very short trail following moving objects. This is excellent for fast-paced content. The response time for this TV is almost identical to the response time of the MU8000 and better than the KS9000 of 2016.

PWM Dimming Frequency
120 Hz

The MU9000 uses PWM at 120Hz to dim the backlight, starting at 20/20 backlight setting. Lowering the setting down to 14/20 lowers backlight amplitude, while lowering it from 13/20 shortens the duty cycle, while amplitude remains constant. Backlight that uses PWM results in duplications following moving objects but does clear up motion slightly.

Update 03/30/2018: Scaled the 'Luminosity' axis of the plots; now the Flicker-Free plots and the new BFI plot have the same 'Luminosity' axis.

Unfortunately, the 'LED Clear Motion' option doesn't reduce the BFI frequency and only dims the backlight. This is the same behaviour as the MU8000 and Q7F.

Update 03/30/2018: It was discovered that many 2017 Samsung TVs change their BFI frequency to 60 Hz when a lot of 60 Hz motion is detected on screen. The score, photo and plots have been updated.

Motion Interpolation
Motion Interpolation (30 fps)
Motion Interpolation (60 fps)

The MU9000 has a 120Hz panel which can interpolate lower frame rate content. To do so, set 'Auto Motion Plus' to 'Custom' and increase the 'De-judder' and 'De-blur' sliders. The 'De-judder' slider affects 30 fps or lower content, and the 'De-blur' slider affects 60fps content. Note that any motion interpolation will introduce artifacts, so use a small value unless you really like the soap opera effect.

The MU9000 is able to display 24p movies from all sources with the correct cadence. To remove judder without adding the soap opera effect, set 'Auto Motion Plus' to 'Custom' and both sliders ('Blur Reduction' and 'Judder Reduction') to 0. The 'LED Clear Motion' feature is not related to judder, but to the black frame insertion feature.

Most common resolutions are supported. 4k @ 60 Hz @ 4:4:4 or 4:2:2 color is only supported when 'HDMI UHD Color' is enabled for the input used. 4:4:4 color is only properly displayed when the input's icon is set to 'PC' (aka PC mode).

PC mode cannot be activated for some input resolutions, such as 24 Hz. The icon will still be PC, but the picture settings that are disabled in PC mode are not disabled, indicating that the TV isn't in PC mode.

Side Inputs

On the side of the TV is one USB, and an ethernet port.

Rear Inputs

The external OneConnect box contains all of the HDMI inputs to the TV.
