Summary : The Samsung 40MU6400 UHD TV, with the exception of the new Tizen interface and the refreshed remote, does not offer anything new compared to last year's KU6xxxx series. TV performs the same in terms of picture quality as last year's models which are now available for a lower price.

Design and handling

samsung-40mu6402-front-design

Samsung 40MU6402 is a classically designed TV set with a V-shaped stand thin bezel. The screen is a semi-glossy textured which means that it can moderately reduce glare and reflections but is not as effective as screens that have special filters (e.g. Ultra Black on Samsung KS SUHD TVs last year or Philips’ Moth Eye TVs).

The bezel is 10 mm wide left, right and above the screen, while the lower part is slightly wider – about 12 mm. When the display is on, you can see an extra 1.5 millimeters of black space between the frame and the active part of the screen. The frame is made of aluminum, unlike the plastic stand.

Samsung’s logo on the bezel does not have a backlight. The status LED is located in the lower right corner and is illuminated red when the TV is in standby mode and completely off when the TV is turned on.

The side view reveals a slim body that is just 15 mm deep next to the bezel, and in the central and lower parts about 55 mm. 40MU6402 features what Samsung calls “a 360 degree design”, which is why the plastic back cover is well-formed, clear with sloping horizontal lines and smooth transitions.

The area where connectors are has no lid as in the case with more expensive models that share “360 design”.

All the connections are on the back facing the side view. To use a CI module, you must remove the label and attach the supplied adapter.

Connections are as follows:

  • 3x HDMI 2.0a, HDMI 3 having ARC functionality
  • antenna and satellite inputs
  • 2x USBs 2.0 (one 0.5 A and the other 1.0 A)
  • Toslink
  • component video and audio inputs (with supplied adapters)
  • Ethernet (LAN)
  • connector for CI module and
  • power connector

The overall build quality is good, at the level of last year’s models. The back cover bends a bit when pushed with fingers, but according to the information we have this year, Samsung uses plastic locks instead of an adhesive that last year was causing separations and gaps, especially on SUHD models with powerful LED backlight. We will follow user comments and analyze each new model in more detail to see if there is any real progress on this issue.

Remote control

With 40MU6402 Samsung supplies slightly refreshed Smart remote which had its premiere last year. It is a compact remote control that in total only has 7 buttons, including multi-functional buttons for volume and channel switching.

Layout and number of buttons did not change, but there are changes in the way some of them are implemented – buttons are now individual, not any more integrated into the cover itself. We believe that this is a step in the right direction because it is easier to find an appropriate button in the dark and pressing gives a better feel. There is also a new texture with circles on the back, although it has a greater visual impact than functional.

Comparison with other remotes on the market

Since last year, Samsung has decided to remove the gyroscope function that was used to show cursor on their earlier remotes. The idea is that those users who want to surf the Internet and write a lot of text rather connect an USB keyboard and mouse or use Samsung’s SmartView app for Android or iOS.

Menus and Smart TV

40MU6402 comes with the latest version of Tizen Smart TV platform which had its premiere in 2015 with the JS-series TVs. At first glance, the platform has not changed significantly – it is just as fast as last year, the layout consists of a strip in the lower part of the screen with applications, inputs and recommended content.

On the global launch of “QLED” TVs in Paris, Samsung said that within the idea of the “Unified Experience” the new Tizen platform will provide even better suggestions based on content users usually watch.  The idea is that user does not go through a huge number apps and different inputs, but that with the help of a remote control and recommendations he can find the desired content more easily.

In practice, this works if you use applications such as Netflix, HBO GO and the like that are appropriately associated with the Tizen platform. In those cases you will see recommendations of content and you can open them directly without having to first open the app and then you are searching for content. In the case of applications that are available only on particular markets, such as MAXtv in Croatia, there are no such recommendations available, at least not for the time being.

The speed of the platform is really good, as you can see in my video below. TV is responsive within 2 seconds after coming from stand-by and apps load quickly.

Menus settings did not change significantly, although some options related to the picture are now moved to other menus, but more about that in the calibration section.

Media player support

Multimedia support via USB or the local network is still at a high level. The built-in player reads all current formats like H.264 / H.265 content in the MKV files, with multi-channel Dolby Digital and DTS, and there is also support for subtitles with the correct display of diacritical marks.

The built-in player also reads the HDR-10 content Ultra HD content with a wide range of colors. The TV has the Plex application.
