The Samsung MU8000 is a capable 4k LED TV that offers good picture quality. Most content will do well on this TV, and it supports modern features such as HDR. Unfortunately, it can't display as many colors as other TVs in its class, and picture quality degrades at an angle.

• Great blacks and contrast
• Low input lag
• Good brightness

• Mediocre color gamut
• Image degrades at an angle

Design

The design of the MU8000 is great. The stand may be too wide for most tables, but it supports the TV well and looks good. The borders are very small, and the TV is very thin so it looks good on a wall or freestanding. The design is an improvement upon the KS8000 from 2016 with the addition of cable management.

The MU8000 has a similar wide stand to the KS8000 from last year. It supports the TV well and feels stable, and also provides cable management routing through the left leg. Unfortunately the remainder of the power cable is quite short (25.2') when routed through the tracks. There are two stand positions available on the 55' model: the narrower position is pictured.

Footprint of the 55' TV stand: 9.7' x 35.5'. There is a secondary wider stand position which is 9.7' x 43.4'.

The rear of the TV has a textured finish very similar to the 2016 KS9000 and KU7000. It looks good and has tracks for cable management (visible here). There are spacers included in the box for wall mounting.

The borders are very thin and look good, similar to the KS8000. The finish is a bit different though.

The TV is quite thin when viewed from the side and would look good when wall-mounted.

The TV stays fairly cool even after extended use, only getting a little warm to the touch along the bottom. The OneConnect box also stays cool, never getting hotter than 32 °C.

The build quality of the MU8000 has improved slightly upon the KS8000 from 2016. The back feels to be more secure, and the joins are more flush.

Picture Quality

The Samsung MU8000 has a good picture quality. The high native contrast provides nice deep blacks which provide a good movie experience when set in a dark room. Bright room performance is also good since the TV can get bright enough to fight glare, but isn't as good as some other TVs at handing reflections. The MU8000 uses a VA panel with a relatively low viewing angle so when sitting off center the picture quality degrades. The gray uniformity is good with very little dirty screen effect which is good for watching sports. When it comes to HDR, the MU8000 performs well and can display a wide range of colors. On the other hand, the local dimming is not that great and the peak brightness in movie mode is good, but not enough to make HDR stand out from SDR.

The native contrast ratio is great on the Samsung MU8000. The high contrast will let the TV produce deep black scenes, especially when viewed in a dark environment.

The contrast ratio, when local dimming is set to 'High', is almost the same (4727:1) as the native contrast ratio. When turned on, the local dimming doesn't really make blacks deeper when measured on our checkerboard pattern. This is because the local dimming feature on the MU8000 doesn't work well.

The local dimming feature of the MU8000 is bad. When compared side by side with the Q7F, both perform almost the same way. It is an edge-lit TV and vertical blooming is visible which follows the bright moving highlight. When watching a movie, blooming is visible in the 2 black bars. Even if the local dimming is not the best, enabling it is still recommended especially for HDR content as it is necessary to produce bright highlights.

Great SDR peak brightness. Under certain conditions local dimming can make small areas incredibly bright, but this only lasts for a short time. In normal usage, the TV will rarely hit this peak, but its sustained brightness is still good enough for even bright rooms. Unlike the Q7F the backlight algorithm doesn't dim scenes of high APL (eg. 100% white window), which is an advantage for rooms with glare. The difference between the Q7F and MU8000 brightness in movie mode can be seen here.

Decent HDR peak brightness. The TV is able to show all content at a decent brightness, and is able to use local dimming to make small highlights even brighter for a short time. The Q7F can get brighter windows in test patterns (see here), but the real scene brightness reflects performance in normal content and the MU8000 performs slightly better in this test.

The overall gray uniformity is good for this Samsung TV. The standard deviation is a bit high though, and this is caused by some darker regions on the screen, especially on both sides. The bottom edge is also a bit problematic since the left side is a bit darker than the right side.

Luckily the TV's dirty screen effect is less problematic, leaving the center region of the screen mostly even. When watching content like football or hockey, where panning shots are more frequent, you don't really notice any dirty screen effect.

The 5% gray uniformity is also very good. the standard deviation and dirty screen effect numbers are even better than the 50% gray, and when looking at our test picture, nothing really negative can be noticed.

Poor viewing angle. Blacks turn grey and colors shift when viewed from the side. People sitting at an angle to the TV will not have as good picture quality as people viewing from directly in front.

Black uniformity is decent on the MU8000. No clouding can be seen in the corners or near the bottom edge, a problem often seen on LED TVs.

When the local dimming is set to maximum, the central vertical blooming is a bit more obvious since both sides of the TV are even darker. This is the main reason why the standard deviation number is higher.

Note that unlike the 2016 Samsung TVs with local dimming, this feature can't be turned off completely on the MU8000 in order to show the TV’s true native black uniformity. As such, the native black uniformity test picture was taken with 'Local dimming' set to 'Low' (the lowest setting) and as a result, some vertical blooming can be seen in our test picture. The black uniformity picture with local dimming was taken with the local dimming set to 'High'.

The TV reflects quite a lot of light, which may be an issue for a bright room. With a few small light sources this is not a problem but if there are any large windows behind the TV then the semi-gloss finish diffuses light across the screen. This is worse than the higher end Q7F.

Out of the box, the MU8000 is very accurate. With both the white balance dE and Color dE under 2.0, this performance is quite good and should be more than enough for normal home use. The only aspect where the MU8000 is a bit less accurate is the gamma, which is not tracking our target of 2.2 very closely. But even then, the overall value is not far from our 2.2 target.

After calibration the MU8000 is even more accurate, with the white balance dE error being reduced to a mere 0.38 which is excellent. The Color dE was reduced a bit less than the white balance dE, but at 1.20 this is still a great result. As for the gamma, after calibration it was flattened to track the target 2.2 gamma more closely.

Overall the calibration process went well, but as is often the case with Samsung TVs, the white balance calibration took a bit longer to accomplish and the color space management could have been more responsive. But in the end, this TV is very accurate, and even with the process taking a bit longer, the results are very good.

Low quality content such as DVDs look quite good. Some halo artifacting can be seen along edges.

720p content is upscaled well. Edges are smoothed well but some haloing is visible.

1080p content such as Blu-rays look good. No issues can be seen.

Native 4k content looks good, and no issues can be seen. The MU8000 doesn't produce the same artifacting as the Q7F when using a warm color temperature, which is good.

Wide color gamut, but not as wide as other comparable TVs like the X900E or Q7F. Colors in HDR content will be reproduced fairly well, although the TV can't show deep green as well as the other colors.

Mediocre color volume. The TV is able to show its wide color gamut at a range of moderate brightness values, but it struggles to show extremely bright or dark deep colors. This should be good enough for most people, but some other comparable TVs like the X900E and Q7F have better color reproduction.

The MU8000 can display our gradient test pattern smoothly with only some small banding in the darker color and also in the darker region of the gray scale. Overall, banding in normal content is not very visible and should not be a problem in everyday use.

The MU8000 is free of image retention. Even right after the burn-in scene, no retention is visible, which is good, especially for the gamers out there.

We don't expect VA panels to experience permanent image retention, as the VA panel in our long-term test appears immune.

Motion

The motion handling of the MU8000 is excellent. The response time is low, which results in only a short trail following fast moving objects. The backlight of the TV flickers, which helps to improve motion even more, but can't be adjusted for people who enjoy a lot of flicker. Movies played from any source can be displayed smoothly, and fans of the soap opera effect can enable very strong motion interpolation.

The response time of the MU8000 is outstanding, resulting in only a very short trail following moving objects. This is excellent for fast-paced content.

This TV 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 KS9000 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.

The MU8000 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.

The MU8000 is decent at playing content without stutter, however some stutter will be noticeable for low frame rate content such as 24p movies due to the fast response time, which results in only a short transition between frames.

The Samsung MU8000 can play movies without judder from any source, such as DVDs, Blu-ray players, native streaming apps or cable and satellite boxes. To remove judder from any source without adding any soap opera effect, set the 'Auto Motion Plus Settings' to 'Custom', 'Blur Reduction' to 0 and 'Judder Reduction' to 0. Leave 'LED Clear Motion' since this does not relate to judder, but to the black frame insertion feature.

The MU8000 doesn't support a variable refresh rate. This is similar to most 2017 TVs. The 49' model is limited to a 60 Hz refresh rate.

Inputs

The MU8000 has very low input lag when in game or PC mode which makes it feel very responsive, and it supports almost all of the common HDMI input signals so it should be able to play nearly any content, including HDR. 3ds max 2014 xforce keygen.

Very low input lag. In game or PC mode, the input lag is 19-25 ms regardless of input, which is great for nearly any game. PC mode had ~ 5 ms less input lag than game mode, but this is negligible. The input lag outside game or PC mode is much higher but is still relatively low, so navigating the TV and using peripherals feels responsive.

Update 06/13/2017: The PC mode HDR bug has been fixed as of firmware 1106, and the 4k @ 60 Hz @ 4:4:4 + 8 bit HDR input lag was remeasured as 21.7 ms.

This TV supports most of the common input resolutions. Chroma 4:4:4 is only supported when the input label has been changed to PC. To display 4k @ 60Hz @ 4:4:4 and 4:2:2, 'HDMI UHD Color' must be enabled.

HDR is not supported in PC mode; the TV displays that it is showing HDR (and the gamma in the settings changes to ST. 2084 as it should), but it does not follow the PQ curve, as shown in this gamma measurement.

Note that unlike the 2018 model NU8000, this TV doesn't support a 120Hz input. It has a 120Hz panel, but this 120Hz motion is achieved through the motion interpolation feature on lower frame rate content.

Update 06/13/2017: This problem has been fixed as of firmware 1106. HDR is now displayed properly in PC mode, as shown by how this EOTF plot roughly follows the HDR PQ curve.

Update 04/25/2018: Clarification about 120Hz input.

The MU8000 uses a mini One Connect box, similar to the KS8000 but smaller than the full size of the Q7F.

For 5.1 audio passthrough, only one of Dolby Digital or DTS can be enabled at a time, the TV will not change between them automatically.

Sound Quality

The sound reproduction of the MU8000 is about average. The TV's speakers produce a good amount of distortion at all levels and the experience would benefit greatly from adding a set of speakers.

Decent frequency response performance. The MU8000 offers a fairly flat response at lower levels, but it quickly turns dark at higher volumes. The TV gets fairly loud, but the volume is better kept under 80dB as compression and pumping artifacts become more apparent past that point.

Below average distortion performance. THD rises as the volume is raised and is audibly noticeable at high levels.

Smart Features

The MU8000 uses Samsung's 2017 Tizen platform. Tizen received a visual overhaul for 2017 and now has a white theme and nicer animations. Unfortunately this visual overhaul caused the interface to have much more frame drops and choppy animations, although responsiveness and speed when navigating the interface are unaffected. Indeed, Tizen is one of the better smart TV platforms when it comes to ease of navigation; the interface is simple and it's easy to find what you're looking for. Voice commands spoken to the microphone on the remote can help the user skip navigating the interface entirely by opening apps and changing settings directly.

The center of the interface is the Smart Hub, which must be navigated to access the rest of the interface. This makes it easy to use, but adds extra steps to accessing things like inputs and settings. This is alleviated somewhat by the second row of the Smart Hub, which contains a quick menu of common settings or recommended content for the item under focus.

The MU8000 has a small ad box on the home screen and in the app store, though it doesn't appear all the time. There is no way to disable these ads.

Out of the box, the TV has many of the most popular apps installed such as Netflix and YouTube, and many more can be downloaded from the included app store. The included apps run smoothly and work properly.

The included remote is very similar to the KS series from last year. It has few buttons which makes it simpler to use, but also means that fewer settings can be accessed directly. This is mitigated somewhat by the voice command functionality of the remote, which allows the user to change settings and open apps directly by speaking commands to the remote's microphone. The remote can also act as a universal remote to control other devices by HDMI CEC or IR.

The Samsung remote app has a few useful features, such as streaming files from the device running the app, but other useful features are missing such as text entry.

The TV has one physical button which can be used to change basic settings. A single press changes between power, input, volume up, volume down, channel up and channel down, while a long press activates the command. This button also doubles as the TV's power button.

Differences between Sizes and Variants

We tested the 55' (UN55MU8000) version FA01. For the most part, we expect our review to be valid for the 49' version (UN49MU8000), 65' version (UN65MU8000) and 75' version (UN75MU8000). The 49' variant does however have a lower panel refresh rate of 60Hz instead of 120Hz.

If someone comes across a different type of panel or if their Samsung MU8000 doesn't correspond to our review, let us know and we will update the review.

The Samsung MU8000 is a good TV, but it isn't very competitive in its price range. It doesn't offer any exceptional features compared to competing TVs at the same price or even cheaper. Overall, the MU8000 doesn't offer great value. See our recommendations for the best smart TVs and the best 4k TVs.

The Samsung NU8000 is marginally better than the Samsung MU8000 for almost every usage. The Samsung NU8000 has slightly better input lag and includes the FreeSync variable refresh rate option, which is great if you play video games. Also, the Samsung NU8000 has marginally better SDR peak brightness and slightly better reflection handling. This allows you to place it in a brighter room where you can enjoy the casual watching of TV shows.

The Samsung MU8000 is a better TV than the Samsung NU7100. The Samsung MU8000 has much better motion handling as it has a judder removal feature and better response time which is great for movies and video games and has better local dimming which improves blacks and picture quality when you watch a movie in a dark room. On the other hand, the Samsung NU7100 has somewhat better black uniformity which is good when watching HDR movies and a bit better input lag when sent 4k @ 60Hz + HDR signal for HDR gaming.

The Samsung MU8000 is significantly better than the Samsung MU7000. The MU8000 has a local dimming feature to improve blacks in a dark room. The Samsung MU8000 also has better motion handling with faster response time, and better motion interpolation for the soap opera effect fans. The MU8000 can get brighter and can handle reflections better if you watch TV shows in a bright room.

If wide viewing angles are important to you, then the Sony X800E is a better choice. Apart from this, the Samsung MU8000 is a better choice. The Samsung MU8000 has significantly better contrast and better local dimming and can deliver great blacks that lead to better picture quality in movies. The Samsung MU8000 also has a bit better motion handling capabilities to improve your movie watching experience further. Finally, the Samsung MU8000 has a bit better input lag and slightly better response time, which is good if you play video games.

The Samsung Q7F is slightly better than the Samsung MU8000. The Q7F has better reflection handling and is a better choice if you have a room with many light sources. The Q7F also has a faster response time and thus a smaller blur trail. The Samsung MU8000, on the other hand, can get brighter and can fight the glare of a bright room.

The Samsung MU9000 is a bit better than the Samsung MU8000. The Samsung MU9000 has significantly better reflection handling which is evident when you watch TV shows in a brighter room. It also has a slightly better contrast that produces better blacks, which you will appreciate when watching HDR movies in a dark room. On the other hand, the Samsung MU8000 has a marginally better response time, and this is great if you play a lot of video games.

If you've got a room with wide seating and many windows, then the LG SJ8500 is a better choice, but for a dark room with seating directly in front, then the Samsung MU8000 is better. The LG SJ8500 has better reflection handling and better viewing angles, which is good if you watch TV shows. The LG SJ8500 also has a somewhat better input lag that makes it very responsive for video games. The Samsung MU8000 has better contrast and better black uniformity that offers deep blacks when watching HDR movies in a dark room. Also, the Samsung MU8000 has a bit better SDR peak brightness and slightly better gray uniformity.

The Sony X850E and the Samsung MU8000 have very similar performance. The Samsung MU8000 has better local dimming and can display deeper blacks when watching movies in a dark room, whereas blacks on the Sony X850E are marginally more uniform. The Samsung MU8000 is a bit better for gaming and HDR gaming as it has a bit better input lag even when sent HDR signal. On the other hand, the Sony X850E has somewhat better reflection handling that you will appreciate if you watch TV shows in brighter rooms.

The Sony X900E is better than the Samsung MU8000 in almost every usage. The Sony X900E has significantly better local dimming and slightly better contrast ratio and can display deeper blacks which is great if you watch movies or HDR content in a dark room. Also, the Sony X900E has better reflection handling, which is good news if you watch TV shows in a brighter room. On the other hand, the Samsung MU8000 has a bit better input lag, and this will please those who play video games.

The Samsung MU8000 is slightly better than the Samsung MU8500. The Samsung MU8000 has a faster response time that leaves a slightly shorter image trail on fast action scenes, and it is marginally better for watching movies due to the better contrast. On the other hand, the Samsung MU8500 is somewhat better for use as a PC monitor due to its curved nature that results in better viewing angles to the edges of the screen.

"Samsung is aware of a small number of TVs in the UK (less than 200) affected by a firmware update to 2017 MU Series TVs on 17th August. Once this issue was identified, the update was switched off and we’re now working with each customer to resolve the issue. Any customers affected are encouraged to get in touch with Samsung directly (0330 7267864).

We would like to apologise for the inconvenience caused to our customers."]

The curse of TV software updates has struck again. Unlike most recent update problems, though, this time it’s owners of Samsung rather than LG televisions who have been affected.

As initially reported by The Guardian, it appears that following a firmware update rolled out last Thursday (August 17), ‘thousands’ of owners of multiple models of Samsung TVs are reporting significant issues.

For some of those affected, their Samsung TV either gets stuck on one channel and won’t reply to remote control commands. For others the TV just gets stuck on the home screen, or else their TVs just won’t turn on at all.

TVs reported as affected include various models from the 2017 MU6, MU7, and MU8 ranges. So far as I can see, there haven’t yet been confirmed issues with any older generations of Samsung TVs, or any of Samsung’s 2017 QLED TVs.

The Samsung UE50MU6100K is one of a number of TVs being widely affected by a recent software update.

It also seems that, strangely, the problems are only affecting European models; there’s no widespread chatter about similar issues on forums or Samsung community boards in other territories. Nor does it seem that the update problems are affecting every MU set; searching through other MU owner forums reveals plenty of people with MU models yet to experience any post-update problems.

Moderators on the European Samsung community boards have fed back, however, that Samsung is aware of the issue, and have also suggested that a fix has already been discovered. However, it seems at the time of writing that this fix requires an engineer visit, rather than being something that can be pushed out automatically.

As well as being inconvenient to customers already frustrated by not having a functioning TV for more than a week now, if the problem really can only be fixed by an engineer visit then sorting out everyone affected could potentially take some time.

Reports on Samsung’s European community forums also suggest that the first engineer visit designed to address the problem ended in failure, with the engineer having to take the TV away for further analysis.

I’ve contacted Samsung for an official response to this situation, and will report back if they have anything to say. Also, if you live outside Europe and have experienced similar issues following last week’s update, or you’ve experienced the same sort of issues with a Samsung model other than those listed earlier, feel free to drop me a note about it on my Twitter feed (linked to at the bottom of this article).
