LG UH6150 LED TV Calibration Settings
Below are the calibration settings we used for our review of the LG UH6150. They are designed for a warm picture look while watching movies, but we also include information on the changes to make for other uses.
We disable all of the energy saving settings first as they cause the backlight to adjust to ambient lighting. This can be distracting and unpredictable at times.
If you plan to use the TV as a PC monitor, first set the input icon to 'PC' to enable support for chroma subsampling, then select the 'Game' picture mode for lowest input lag. For gaming, also use the 'Game' picture mode.
For other uses select the 'Expect (Dark Room)' picture mode as it allows all of the settings to be adjusted for best performance.
We set the 'Backlight' to 60 for our completely dark room. You can set this to your preference without affecting the picture quality, and this will depend upon the ambient light level. We leave the 'Brightness' to the default value, and adjust the 'Contrast' to 100 to achieve the greatest native contrast range. Reduce both the 'H Sharpness' and 'V Sharpness' to 0 to avoid any over-sharpening.
Leave color and tint to their default values.
We aim to have a picture which is as close to the source material as possible, and in order to do this we disable all image processing. This includes 'Dynamic Contrast', 'Super Resolution' and 'Edge Enhancer'.
For SDR content, leave the 'Color Gamut' to 'Normal' for the most accurate image. The TV can display slightly more colors with the 'Extended' setting so enable it for HDR.
We set the 'Gamma' to 2.2 as it is closest to our calibration goal.
We aim to calibrate to a color temperature of 6500K, so we set the color temperature to 'Warm2'. Note that this does reduce the contrast ratio and the brightness of the image, as the white sub-pixel is cool. For a higher native contrast ratio you can use a cooler setting, but this sacrifices some of the picture accuracy.
Disable 'Noise Reduction' and 'MPEG Noise Reduction' when watching high quality content. If you watch lower quality content such as DVDs or cable then you can enable these settings to reduce some of the noise.
Adjust the 'Black Level' to suit your source. For PC use it is normally a black level of 'High' for a full-range RGB source, and for other devices it is usually 'Low'. When incorrectly set, the blacks will appear more gray or shadows may be crushed.
Disable 'Motion Eye Care' to reduce processing.
'TruMotion' is the motion interpolation setting. Enable this if you like the soap opera effect, otherwise leave it disabled.
To use a higher bandwidth source such as 4k @ 60Hz @ 4:4:4, enable 'HDMI UHD Deep Color' for the HDMI port.
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.
