The following are the calibration settings used in our review of the LG UH9500 LED TV. They are designed for watching movies, however can be adjusted to any usage with the tweaks described below.
To begin, we disable any 'Energy Saving' options to achieve the best and most consistent performance.
We select the 'Expert (Dark Room)' picture mode. This results in the most accurate picture, and allows most control over the picture settings. For those looking to use the TV as a PC monitor or for video games, select the 'Game' picture mode for lowest input lag. To enable chroma subsampling support for clearest text when using as a PC monitor, change the input icon to 'PC'.
We set the backlight to 21, for our completely dark room. You can adjust this to your preference without affecting the picture quality. We change the 'Contrast' to 100, as it gives us the best resulting gamma curve. We reduce both the 'H Sharpness' and 'V Sharpness' to 0, to prevent any over sharpening of images.
We leave the 'Color' and 'Tint' to their default values.
We disable all image processing, such as 'Dynamic Contrast', 'Super Resolution' and 'Edge Enhancer'. This is to provide us with the most true image to the source material. We also use the 'Normal' color gamut for this SDR calibration. Adjusting this makes SDR content look over saturated. It is automatically adjusted to the wide color gamut and so does not need to be changed. We set the 'Gamma' to BT.1886 as it is closest to our calibration goal.
For high quality content, we recommend disabling 'Noise Reduction' and 'MPEG Noise Reduction'. For watching lower quality content such as DVDs you can enable this to clear up artifacts and noise. We also recommend disabling 'Local Dimming' as it doesn't work well on this TV.
'TruMotion' is the motion interpolation feature. Enable this if you enjoy the soap opera effect.
We use the 'Warm1' color temperature, as it is closest to our goal of 6500K.
To enable support for 4k @ 60Hz @ 4:4:4 or for HDR content, enable 'HDMI ULTRA HD Deep Color' for the port your device is connected to.
The following are the results of the white balance and colorspace calibration on our unit. You can try copying our values for these, but we don't recommend them as they vary per individual unit, so they might not be good, even for the same model and same size as the TV we reviewed. 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.
