On this page you can find the calibration settings we used for our review of the LG UH5500. Although they are designed for watching movies, there are descriptions below on how to adjust these settings to suit your specific use case.
First we disable all of the energy saving settings. These adjust the backlight depending on the ambient lighting, and can cause distracting changes to the picture.
We use the 'Expert (Dark Room)' picture mode for watching movies.This mode allows us to fine tune the settings of the TV for best performance. If you plan to use the TV as a PC monitor then first set the input icon to 'PC' to enable chroma subsampling, and then set the picture mode to 'Game'. For gaming use change the picture mode to 'Game' and then follow our settings.
Adjust the backlight to your preference. This depends on your room and the amount of ambient light. You can change this without affecting the picture quality. Leave the brightness to the default value, and set contrast to 100 because it improves the 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 disable all image processing, as our goal is to have a picture which is as close to the source content as possible. This means disabling 'Dynamic Contrast', 'Super Resolution' and 'Edge Enhancer'.
We leave the color gamut as 'Normal' for SDR content. This TV doesn't support a wide color gamut so leave it at normal regardless of the content.
We set the 'Gamma' to 2.2 as it is closest to our calibration goal.
We use the 'Warm2' color temperature, as it is closest to our goal of 6500K. If you find the picture too yellow or dull, you can adjust this to a cooler value.
We disable 'Noise Reduction' and 'MPEG Noise Reduction'. This is not recommended for high quality content such as Blu-rays but should be enabled to clear up any noise when watching lower quality content such as cable.
Adjust the 'Black Level' to suit your source. For PC use it is normally a black level of 'Low', and for other devices it is usually 'High'. 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.
