LG C6 OLED TV Calibration Settings
The following are the calibration settings we used for our review of the LG C6. These settings will work well with everything except for gaming or PC use. To have the best picture quality while gaming with this TV, simply change the picture mode to 'Game Mode' and change the input icon to 'Game Console' as this will lower the input lag. To use as a PC monitor, change the input icon to 'PC' to enable chroma subsampling, and set the picture mode to 'Game Mode'.
We start off by turning off the 'Energy Saving' option. This will disable the automatic brightness setting.
We set the picture mode to 'Expert (Dark Room)' to enable use to adjust the expert settings. We adjusted the 'OLED Light' to match our room environment, you can increase the 'OLED Light' as much as you would like to match your room, it will not affect the colors. After we increased the 'Contrast' to 100 so that we could get the maximum range of contrast available. We also adjusted the 'H Sharpness' as well as the 'V Sharpness' to 0 so there wouldn't be any over-sharpening.
We left 'Color' and 'Tint' to their default values as it didn't benefit the results.
In 'Expert Control' we turned all the processing settings off. We also put the 'Color Gamut' to normal and put the 'Gamma' settings to 2.2 as it was the closest to our desired gamma curve.
In the 'White Balance' settings we put the 'Color Temperature' to 'Warm2', since it was the color temperature that gave the closest result to our calibration goal.
In 'Picture option' we turned off 'Noise Reduction' and 'MPEG Noise Reduction'. You can turn those options on if you are viewing some older low resolution content, but it is not needed with newer high quality content. We left 'Black Level' to 'Auto', since this way it will automatically adjust to the good RGB value.
It is also important to turn on the 'HDMI ULTRA HD Deep color' support for any HDMI ports which are connected to a HDR UHD Blu-ray player or a HDR gaming console to benefit from the maximum bandwidth of the HDMI port. Not enabling this option may result in some errors or incompatibility when trying to view some specific content. This is also necessary to enable the bandwidth needed for 4k @ 60Hz @ 4:4:4 from a PC.
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.
