Gaming and PC connectivity
| Characteristic | Result |
| PC preset | Available |
| 1:1 pixel mapping | Yes |
| 4:4:4 FHD i UHD color resolution | Yes, but only in PC mode |

The 40MU6402 continues Samsung’s practice of TVs that have very low input lag but with poorly adjusted Game and PC modes in terms of color accuracy.
In addition, except that Game mode has been moved deeper into the menu structure that users find it harder to find (see video below), there is a permanently active global dimming when a dark image is displayed on the screen. The only solution Samsung offers is in PC mode where global dimming is not active. However, in PC mode you will be limited to the Native color gamut, meaning that TV will oversaturate all colors in case or Rec.709 or sRGB colorspace of the original content. This is a big disadvantage for all who plan to use the TV as a monitor, especially if they deal with sensitive color work. Fortunately, the 40MU6402 can not display a significantly larger color range than the Rec.709 standard, and the colors are not as saturated as, for example, on expensive models from the “QLED” line, but we warmly hope that Samsung will correct this soon.
Playing games was a good experience, with high contrast images and quick response to our controls. The only thing that might bother gamers is low motion resolution, especially in dark scenes.
Sound quality
The sound quality of the new 40MU6402 TV is the same as on the last year’s 6000 series TVs. The midrange is clean, without distortions at normal volume, but the sound lacks the fullness of the low frequencies as well as the details in the high tones.

Alternatives
An excellent alternative is, if you are looking for a TV with similar contrast and you are not interested in UHD and HDR, the Panasonic TX-40DS630E. From the Samsung range, see the Samsung 40KU6000 or another model of the KU6xxxx series.

Hello,

Hello Darco,
One question regarding UE40MU6402.
On the bottom edge of this TV do you have any issues regarding light? I mean comb effect light and dark for 2 cm of all bottom edge of the screen. I think there is the LED for light.
Please see an video for exemple https://www.youtube.com/watch?v=0VWnqKS0ctU
Thank you very much.
Hello Catalin!
Saw the video, this is a typical limitation of edge-lit LED LCD TVs. It varies from unit to unit so as long as the anomaly is not so big that is distracting while you watch content, no reason to contact service center.
Hello. Does the 2k Resolution (2560×1440) work on this TV connected to a PC?
Yes, it supports that resolution.
Hi Darko,
Thank you very much for your work!
I have calibrated the colours according to your video on YouTube and I like the results!
However, there is one thing I don’t know/don’t understand: If I watch actual 4K movies, should I select bt.2020 or dci-p3 ?
Thank you.
Sorry, you already replied on YouTube ^_^
