Samsung NU6900 LED TV Calibration Settings

These are the settings we used to calibrate the Samsung 55 inch UN55NU6900 TV and we expect them to be valid for the 43 inch version (UN43NU6900), 50 inch version (UN50NU6900), 65 inch version (UN65NU6900) and 75 inch version (UN75NU6900). These are suitable for any content, from watching movies to TV shows and gaming. For Gaming, some adjustments need to be done, and they are listed below.

General Settings

Samsung NU6900 Calibration Settings 24

The first thing we did was to turn off all of the 'Eco Solution' settings since we didn't want the backlight level or picture settings to change during our calibration. This is recommended if you don't want the brightness of the TV to change automatically depending on the room brightness.

For movies and TV content, the 'Movie' picture mode gave us the closest results to our calibration goal and it should bring the image quality closest to what the content creator intended it to be.

A Backlight setting of '15' gave us a luminosity closest to our calibration target of 100 cd/m². Most people will find this too dim and should adjust it. Note that adjusting the backlight setting has no impact on picture quality. We left the Brightness to '0'Contrast to '45' and Sharpness to '0'. We also left Color to '25' and the Tint (G/R) to their default values of 'G0 and R0'.

Expert Settings

We turned Digital Clean View to 'Off'. If you are watching older, low-resolution content, you may want to set it on to make the content smoother and with fewer compression artifacts. For our calibration, we left the Auto Motion Plus Settings to 'Off'.

Contrast Enhancer was also left turned 'off' since we don't want to add any extra image processing to keep the content as faithful to the original intent.

Motion Interpolation (Soap Opera Effect)

The Auto Motion Plus Settings controls the NU6900's motion interpolation. Since it has a 60Hz panel, it can only interpolate 30 fps content up to 60Hz. To do so, set Auto Motion Plus to 'Custom' and increase the 'Judder-Reduction' slider to your liking to add more or less soap opera effect.

Color and Gamma

We selected the 'Warm2' 'Color Tone' since it was the closest to our calibration goal, but you can change it to a cooler 'Color Tone' if you find the color too yellow or red.

The gamma setting adjustment was set to '0' since it was the closest to our calibration goal. The TV will automatically set the Gamma type automatically depending on the content. You should 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.

In the Color space setting, 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. Setting the Color Space to 'Custom' will allow calibrating the TV for SDR content. If you set the Color Space to 'Custom' you will have to adjust the settings each time you change from SDR to HDR.

PC Monitor Settings

Samsung NU6900 Calibration Settings 45

For use as a PC monitor, PC Mode can be enabled by setting the Device Type to 'PC' from the Input Device Manager submenu (you can access this menu from the 'Sources' tab from the home page). The TV will only display properly a chroma 4:4:4 signal when the PC mode it selected. When in PC Mode, a Sharpness setting of 10 is the default neutral setting. It is not possible to add sharpness, instead of decreasing the setting will soften the image.

HDR Settings

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 HDR content (from the 'External Device Manager' menu). This will permit the HDMI port to transmit all the bandwidth needed for HDR and tells the TV to expect a 10-bit color signal on that input. If the 'HDMI UHD Color' is not turned on, some devices will not detect the NU6900 as being compatible with HDR. For HDR content, it is also preferable to set the Backlight to maximum and set the Color Space Settings to 'Auto'.

Gaming Settings

Samsung NU6900 Calibration Settings 23

To enable Game Mode, select External Device Manager from the General menu, and then set Game Mode to 'On'. It is recommended to set the HDMI Black Level to 'Auto'. For SDR gaming set Sharpness to '0' to remove any sharpening. To enable chroma subsampling when playing from a PC, set the device icon to 'PC' under the Input Device Manager submenu.

HDR Gaming Settings

For HDR gaming apply the same HDMI settings mentioned in the HDR settings and game settings above. Note that when in game mode, the TV won't change the Backlight setting automatically, so it is preferable to set the Backlight to max. If you find the HDR settings too dim you can follow the instructions on the Color Gamut box on the review as to how to make it brighter 

White Balance

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.
