LG UK6300 Calibration Settings


For additional settings information, please consult the Common Problems and How to Calibrate pages.

Here are the following settings we've used for the calibration of the LG 43" UK6300 (43UK6300 ), and these should also work for the 49" variant (49UK6300), the 55" variant (55UK6300 ) and the 65" variant (65UK6300 ). These settings do not apply to the 50" variant available in some countries (50UK6300). These should work for most content except for gaming which requires some minor changes, which we list below.

Eco Settings

Before starting our calibration we disable all eco settings. We set Energy Saving and Eye Comfort Mode to Off, as we don't want the TV to artificially limit the brightness of the TV or change any settings while we are doing our testing.

General settings

The first thing we did was to select the 'ISF Expert (Dark Room)' picture mode. If you are in a bright room, ISF Expert (Dark Room) will probably be too dim. We select it because it is the most accurate picture mode. If you find it too dim, Standard mode is a decent alternative. We set the 'Aspect Ratio Settings' to '16:9' since we did not want our input to be stretched in any way. When watching lower resolution content you can adjust this setting to stretch the image depending on your preferences.

For review purposes and in our completely dark room, we adjusted 'Backlight' to 46 to reach our desired luminance of 100 cd/m². Most people will find this too dim and should adjust it. Note that this does not affect the color accuracy, only the luminance of the display. We then set the 'Contrast' to 90 and left 'Brightness' to 50, its default value. We also left 'Sharpness' to 0, since we don't want to add any extra sharpening.

We left 'Color' to 50 and 'Tint' to 0, their default values.

In the 'Expert Controls' settings page, we turned off 'Dynamic contrast', 'Super Resolution', and 'Color Filter'. We set the 'Color Gamut' to 'Auto', so the TV will switch the color gamut automatically to match the video source. The gamma was changed to 2.2, since it is the gamma that we aim for during calibration.

In the 'White Balance' settings, we selected 'Warm2' from the 'Color Temperature' settings since it is closest to our calibration goal.

In the 'Picture Options' menu, we turned off 'Noise Reduction' and 'MPEG Noise Reduction', but you can turn on these on if you are watching older low-resolution content, as it may help reduce visual noise and compression artifacts. We set the 'Black Level' to 'Low' to match our source 'Output Dynamic Range'. When set wrong, blacks will look much more grayish or may be crushed. We left 'Motion Eye Care' off since we did not want the TV to change brightness automatically depending on the displayed scene. The 'Real Cinema' option should be turned on if you are watching a 24p movie via a DVD or Blu-ray player in order to have a judder-free movie.

The 'TruMotion' is the motion interpolation option, commonly called the Soap Opera Effect. When watching low frame rate content like 24p movies the TV can insert extra frames to help motion appear smoother. Since this TV has a 60Hz panel the effectiveness of this is limited. To enable it set 'TruMotion' to 'User' and adjust the slider to add the level of desired soap opera effect.

HDR settings

First thing to do is to turn on 'HDMI ULTRA HD Deep Color' for the HDMI port where you intend to connect your HDR UHD Blu-ray player or UHD game console, as some players may not detect that the TV can support the full HDMI bandwidth necessary for HDR content. Not that there is no difference between ports on the UK6300, and you can use any port for HDR content.

When the TV detects HDR content, it will give you 5 'HDR Picture Mode' options. For movies, the 'Cinema' picture mode is the best option available since it will give you more control of the settings, similar to what you have access with 'IFS Expert (Dark Room)' with SDR content.

SDR and HDR Gaming settings

To get the best input lag possible when gaming whether you are in SDR or HDR, you need to set the 'Picture Mode' to 'Game (User)'.

LG UK6300 Calibration Settings 53

Once the 'Game (User)' picture mode is selected, some options won't be available in the setting pages as the TV disables most of the image processing to give better input lag. For 'Game' and 'PC' modes, the most accurate picture was obtained with color temperature set to W34, 'Color' set to 50, and 'Dynamic Tone Mapping' enabled. For 'Game' mode, also set 'Dynamic Contrast' to Medium.

Miscellaneous settings

If you want to activate the Chroma subsampling (4:4:4) on the UK6300, you need to set the 'Input Label' to 'PC' (from the input menu) for the HDMI port where your device is connected. For high bandwidth signals, be sure that the 'HDMI ULTRA HD Deep Color' is also turned on.

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.
