These are the calibration settings we used for our review of the LG E6. These settings will work well with everything except for gaming. To have the best gaming experience with this TV we advise changing the picture mode to 'Game Mode' as this will lower the input lag.
Start off by selecting 'Expert (Dark Room)' as the 'Picture Mode Settings'. This settings will be great for watching movies, TV shows and sports.
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 effect the colors. We then increased the 'Contrast' to 100 which seemed to help with our calibration a great deal. 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.
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 seemed to benefit our calibration. If you find that the blacks are crushed you can use 'Gamma' 1.9.
In the 'White Balance' settings we put the 'Color Temperature' to warm.
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.
