These are the settings we used to calibrate the Samsung 55 inch MU6290 (UN55MU62900) LED TV and we expect them to be valid for the 40" version (UN40MU6290), 43" version (UN43MU6290), the 49" version (UN49MU6290), the 65" version (UN65MU6290) and 75" version (UN75MU6290). These are good for any content, from watching movies to TV shows and gaming. For Gaming, some minor adjustments need to be done, and they are listed below.
The first thing we did was to verify that all of the 'Eco Solution' settings were set 'Off" since we didn't want the backlight level to change during our calibration. This is recommended if you don't want the luminance of the TV to change automatically depending on the room brightness.
For movies and TV content, we selected the 'Movie' 'Picture Mode', since it is the picture mode that brought us the closest to our calibration goal. The 'Movie' 'Picture Mode' is recommended as it should bring the image quality closest to what the content creator intended it be and it also gives you more freedom with all the picture setting available.
The 'Picture Size Settings' was set to '16:9 Standard' as this is the screen format of the MU6290, and the 'Fit to Screen' option was set to 'On', as it will help to resize the HDMI video input so that it fits good in the TV, without you having to play with the video output of your external device.
To have a luminosity closest to our calibration target of 100 cd/m² in our totally dark room, we used a 'Backlight' setting of '6 '. Note that you should change 'Backlight' to match your room lighting and it won't affect the picture quality. To correct the white balance and gamma issues, we set the 'Brightness' to '1' and the 'Contrast' to '90'. We left the 'Sharpness' to '0' to avoid any oversharpening. We left the 'Color' to '50' and the 'Tint (G/R)' to its their default value of 'G50 and R50', for the most accurate image.
We turned 'Off' the 'Digital Clean View', but if you intend to watch some older low-resolution content, you might want to set it to 'On' to make the content smoother and with fewer compression artifacts. For our calibration, we left the 'Auto Motion Plus Settings' 'Off' (more on that later), left 'Contrast Enhancer' 'Off' and left unticked 'HDR+ Mode' (this extrapolates HDR from SDR, creating a fake HDR).
In the 'Auto Motion Plus Settings' tab, you can control the motion interpolation and the black frame insertion feature. When 'Auto Motion Plus' is set to 'Custom', You can adjust the slider of 'Judder Reduction' to add the amount of soap opera effect you want, but note that since this TV has a 60Hz panel, the soap opera effect won't be as strong as on 120Hz TVs. The 'LED Clear Motion' controls the black frame insertion and can help to reduce the motion blur, but it will dim the TV image considerably and will introduce some screen flicker. You can read here to learn more about the black frame insertion feature.
We selected the 'Warm1' 'Color Tone' since it was the color temperature the closest to our calibration goal, but you can choose a colder color temperature if you find the color of the screen too warm (yellow or red).
The 'Gamma' 'BT.1886' was adjusted to 1 to reach our calibration goal of 2.2 gamma. Note that here, the gamma type is set automatically depending on the type of content you are watching. You can only adjust the gamma curve with the slider (plus or minus) if you find there is black crush or if dark scenes are not deep enough. For the calibration process, you need to set the 'Color space' to 'Custom' to be able to do any correction to the color space, but if you don't intend to do any calibration, it is preferable to leave it to 'Auto'. When set to auto, the color space changes to match the type of content you are watching automatically.
For watching HDR content via an HDMI connection, it is important to set the 'HDMI UHD Color' on for each HDMI input that will receive the HDR content. This will permit the HDMI port to transmit all the bandwidth needed for HDR. If the 'HDMI UHD Color' is not turned on, some devices will not detect the Samsung MU6290 as being compatible with HDR or if you connect the MU6290 to a PC, you won't be able to send the more demanding resolution (like 4k@60Hz). For HDR content, it is also preferable to set the 'Backlight' to maximum and set the 'Color Space Settings' to 'Auto'.
SDR Gaming Settings
To have the best input lag while playing games via a video game console or PC, you can keep the general settings mentioned above and turn on 'Game Mode' from the 'External Device Manager'.
If you are using a PC, then set the input icon to 'PC', from the smart TV homepage, if you want to enable the chroma subsampling.
HDR Gaming Settings
For HDR gaming apply the same HDMI settings mentioned in the HDR settings and game settings above.
White Balance and Color Space Settings
The following are the results of the white balance and colorspace calibration on our unit. They are provided for reference, and should not be copied as the calibration values vary per individual unit even for the same model and same size as the TV we reviewed due to manufacturing tolerances. If you want to try them you will need to enter all values shown, as all of them are active at the same time. If you end up with worse picture quality, simply reset them to the default values.
