The Samsung MU6300 is a better than average 4k Smart LED TV. It's not very extravagant, but it provides decent picture quality and a good set of features. Its input lag is noticeably better than average, making it a good choice for gamers. Picture quality does, unfortunately, degrade quite rapidly at an angle, and it could be a bit brighter to better accommodate well-lit environments.

Pros
  • Great native contrast ratio
  • Low input lag, games are responsive
Cons
  • Limited HDR capabilities
  • Picture quality degrades at an angle

Design

Curved : No

The design of the MU6300 is good. It is almost identical to the KU6300 from 2016, and won't turn many heads. The stand supports the TV quite well and the borders are an average thickness. The build quality is similar to other competing TVs.  

Stand

The V-shaped center stand is iconic of Samsung TVs, and looks very similar to the KU6300 from last year. If knocked, the TV does wobble quite a bit but is still quite stable.

Footprint of the 55" TV stand: 12.1" x 33.2"

Back
Wall Mount : VESA 400x400

The back of the TV looks the same as the KU6300 and is all plastic. All of the inputs can be accessed from the side, which is great for those who place the TV near a wall. The controls are also relatively easy to access.

Borders
Borders : 0.67" (1.7 cm)

The borders of the TV have an average thickness. They are made of plastic.

Thickness
Max Thickness : 2.56" (6.5 cm)

The thickest part of the TV is near the bottom, but it won't stick out too much if wall-mounted.

Temperature
Maximum Temperature
:
102 °F (39 °C)
Average Temperature
:
97 °F (36 °C)

The MU6300 gets warm to the touch along the top, sides and at parts of the back of the TV, but this shouldn't be a problem.

6.5 Build Quality

The build quality is the same as the KU6300 from 2016. The stand feels a bit cheap but the TV certainly isn't going to fall apart from normal use.

7.4

Picture Quality

The Samsung MU6300 TV has a better than average picture quality. Its excellent contrast ratio and amazing black uniformity help the TV to display dark scenes with a lot of detail, especially when set in a dark environment. When set in a brighter room, the MU6300 doesn't fare as well since it cannot really get bright enough to fight glare from bright lights or sunny windows. The gray uniformity is not that great and dirty screen effect is visible, especially when watching sports like hockey. The viewing angle is bad on the MU6300, so it will be better suited for rooms with a narrow seating since the picture quality is best when viewed from directly in front. When it comes to HDR, the lack of local dimming and of a wide color gamut really hurt its capacity to make HDR stand out when compared to SDR content.

9.0 Contrast
Native Contrast
:
5768 : 1
Contrast with local dimming
:
N/A

Excellent native contrast ratio for the Samsung MU6300, like the 2016 KU6300. With 5768:1 contrast ratio, the MU6300 can produce very deep blacks and can provide a good movie experience when set in a dark room.

Update 09/21/2017: The 43" size likely uses an IPS panel, according to many user reports. This means that it will have a contrast ratio of ~1000 cd/m², which results in a sub-par contrast score of 6.0.

Good SDR peak brightness. The TV will appear bright even in a fairly bright room, though in a very bright room it may appear too dim. The MU6300 has less aggressive CE dimming than the KU6300 from last year, as the 10% window test was not dimmed unlike on the KU6300. However the MU6300 is not as bright as the KU6300, even with this less aggressive dimming. A plot of peak brightness over time is shown here.

Okay HDR peak brightness. Most of an HDR scene will be shown bright enough, but highlights will not reach anywhere near the 1000-4000 cd/m² they're intended to reach. Very dark scenes will be dimmed by the TV's CE dimming, but because the TV lacks local dimming, the highlights will be dimmed along with the rest of the scene. A plot of peak brightness over time is shown here.

The MU6300's overall gray uniformity is ordinary. There are some large vertical bands visible in the center of the screen, which unfortunately creates some dirty screen effect when watching sports like hockey. Both the left and right sides are also darker than the rest of the screen, but since the center is ok, it results in less dirty screen effect.

The top and bottom edges are brighter than the rest of the screen and this is clearly visible on both the 5% and 50% gray test picture. This problem is less visible when watching normal TV content, but can be visible when uniform colors are displayed near the edge and can be distracting.

Poor viewing angle. Blacks turn grey very rapidly at an angle; colors shift and brightness decrease not long after. People sitting to the side of the TV will not have as good picture quality as people seated directly in front.

Update 09/21/2017: The 43" size likely uses an IPS panel, according to many user reports. This means that it will have a much better viewing angle, resulting in a decent score of ~6.5.

9.2 Black Uniformity

The MU6300 has an excellent black uniformity, similar to the 2016 KU6300. Looking at our test picture, you can see that the blacks are pretty even and the whole screen is free of major clouding issues, which is great especially for dark scenes in movies.

7.5 Reflections

:
Semi-gloss
Total Reflections

Indirect Reflections

The MU6300 is okay at handling reflections. It has a semi-gloss finish which reduces the intensity of direct reflections but also diffuses them across the screen. For an average room this isn't much of an issue, but in a bright room this may be a problem.

Out of the box, the pre-calibration had some issues, but most of them are because the Samsung MU6300 is tracking the gamma BT.1886 instead of the more traditional gamma 2.2 (LG TVs also use BT.1886 out of the box). This is not a bad thing on its own and overall, the TV could be used as-is without too many issues.

The calibration process is a bit more difficult to perform on the MU6300 and Samsung TVs are in general a bit more tricky to calibrate. Even with the slightly trickier calibration, the final result is excellent. The white balance dE was brought down to a negligible 0.22. which is very good. As a result of the white balance correction, the gamma curve was flattened and now tracks closer to our 2.2 target.

The color dE was also brought down to 1.62 using the color management system, but some saturation targets in the blues and reds were still a bit off and could not be corrected without creating other problems. Overall this is a good result.

You can see our recommended settings for this Samsung MU6300 TV here.

8.0 480p Input

Upscaling of low-quality content such as DVDs is good. The image is a little bit soft, but details are preserved.

8.0 720p Input

720p content such as cable looks good. The image is a little bit soft but there is a minimum of upscaling artifacts.

9.0 1080p Input

1080p content is upscaled well. The image remains clear and detailed.

The TV has a narrow color gamut, which can only properly show colors in the SDR Rec 709 color gamut. Most colors in HDR content will be shown properly, but deep colors will be desaturated to fit within the TV's gamut. On the bright side, the TV is fairly accurate when showing the colors within its gamut.

The TV's EOTF follows the HDR PQ curve fairly well, and rolls off gently to its maximum brightness, though it starts rolling off sooner than most TVs. This EOTF was taken in Movie mode; the EOTFs for game and PC mode are shown here and here, and aren't much different.

The TV has a narrow color gamut and lacks local dimming, so it can't produce a good color volume. Its CE dimming helps it darken dark colors, but its color gamut also narrows for dark colors.

Motion

The motion handling of the MU6300 is mediocre. The response time is good, resulting in a fairly short trail following fast moving objects but those sensitive to judder will notice it when watching movies from any source. The backlight uses PWM to flicker so motion isn't quite as smooth as some other TVs. The TV has a 60Hz panel which can interpolate lower frame rate content.

7.6 Response Time
80% Response Time
:

100% Response Time
:

The response time of the MU6300 is good, resulting in only a short trail following moving objects. It isn't as good as higher-end Samsung TVs such as the MU8000, but is similar to the KU6300 of 2016. This isn't a problem for most people.

4.0 Flicker-Free

:
No
PWM Dimming Frequency
:
120 Hz

The MU6300 uses PWM at 120Hz to dim the backlight, starting at 12/20 backlight setting. Lowering the setting from 12/20 shortens the duty cycle, while amplitude remains constant. PWM causes a duplicated trail following moving objects in 60Hz content so motion isn't as smooth as TVs without a flickering backlight.

The MU6300 can't remove judder from 24p movies playing from 60Hz sources, and can't adjust the refresh rate to display 24Hz sources with the correct cadence. This is the same result as the 2016 KU6300. Note that not many people are sensitive to judder so it may not necessarily be a deal breaker.

4:4:4 color is only properly supported in PC mode, which is activated by changing the icon of the input used to 'PC'. PC mode doesn't work for some input frame rates such as 24 Hz; the icon may still display PC, but the settings that are normally disabled in PC mode such as color and tint are not disabled, indicating that PC mode isn't active.

Smart Features

Smart OS : Tizen
Version : 2017

The MU6300 runs Samsung's 2017 Tizen smart platform, which is easy to navigate but has more frame drops in its animations than last year's Tizen. The home menu is a narrow bar at the bottom of the screen, and most smart features can be accessed without leaving this home menu, making the interface easy to use. Voice commands from the remote's microphone also allow many tasks to be done directly, such as changing settings and searching for content, without having to navigate the TV's interface.

Differences between Sizes and Variants

We tested the 55" (UN55MU6300) version FA01. For the most part, we expect our review to be valid for the other sizes of this model.

Update 09/21/2017: The 43" size likely uses an IPS panel, according to many user reports, so our review is not a good indication of this size's performance. An IPS panel will have a much worse contrast ratio but a much better viewing angle than the VA panel unit we tested, which will change our overall scores significantly.

If someone comes across a different type of panel or if their Samsung MU6300 doesn't correspond to our review, let us know and we will update the review.

Black Friday Models

A few retailers have a slightly different variant of the MU6300 on sale for Black Friday with the model names MU6290 or 6 Series Holiday Smart TV. We expect these models to perform similarly to the to the size we've reviewed, with the only differences being the standard remote (unlike the voice-enabled smart remote of the MU6300) and the lack of Bluetooth connectivity. 

It can be found at Walmart, BestBuy, Costco, Target, and Kmart in 40" (40MU6290, UN40MU6290 UN40MU6290F, UN40MU6290FXZA), 49" (49MU6290, UN49MU6290 UN49MU6290F, UN49MU6290FXZA), 55" (55MU6290, UN55MU6290 UN55MU6290F, UN55MU6290FXZA) and 65" (65MU6290, UN65MU6290 UN65MU6290F, UN65MU6290FXZA).

BestBuy also has their own exclusive model with product number MU6070. It is identical to the MU6290 above but with 1 less HDMI port (2 instead of 3) and no composite input. It is found in two sizes: 50" (UN50MU6070FXZA) and 65" (UN65MU6070FXZA).

58"

The Samsung MU6300 is marginally better than the Samsung MU6100. The Samsung MU6300 has somewhat better black uniformity and better contrast that produce deep blacks in dimmer rooms. It also comes with better out of the box colors leading to better picture quality in movies, and a slightly better response time which looks good in fast action video games. The Samsung MU6100 has better reflection handling and viewing angles, which are a plus when watching TV shows in a large room with many windows.

40" 43" 49" 55" 65" 75"

The Samsung MU6300 and the Samsung MU6290 perform very similarly, and there is no significant difference between the two. The Samsung MU6300 supports Bluetooth out of the box.

7.4 Mixed Usage
The MU6300 is a decent TV for a mixed usage. Picture quality is passable, and it has most of the features needed without any major flaws. That also means it doesn't excel anywhere though.
6.7 Movies
Below average TV for watching movies. The MU6300 produces deep and even blacks, but it lacks a local-dimming feature and has some issues displaying native 24p content without judder. Not everybody notices that issue though.
7.5 TV Shows
Decent TV for watching TV shows. It handles reflections well and gets sufficiently bright for most environments. The Samsung SmartHub also provides a decent amount of apps to access content.
7.2 Sports
Average TV for watching sports. The picture is decently uniform, but the motion performance leaves a bit to be desired. Some dirty screen effect is also apparent.
8.2 Video Games
Very good TV for playing video games. Input lag is amongst the lowest available. Motion is decent also, which is good for clarity of faster-paced games.
6.8 HDR Movies
Passable HDR movies performance. While the MU6300 has some of the essential features on board, it doesn't get particularly bright or cannot display a wider range of colors.
7.7 HDR Gaming
Better than average for HDR gaming. Input lag remains low at every setting, which is essential. The actual effect of HDR could be better though.
7.8 PC Monitor
Below average for use as a PC monitor. Essential resolutions are present, but trails following moving objects are a bit longer than desired. The narrow viewing angles also cause corners of the screen to darken if used from up close.
