LG UM8070 Calibration Settings

We used the following calibration settings to review the LG 82" UM8070 (82UM8070), and we expect them to be valid for the 86" model (86UM8070). These settings should apply to most types of content, except for gaming or use as a PC monitor, which require a few additional changes, listed below.

One of the first things we did was disable all of the power saving and automatic image modes, as we don't want the TV to adjust the image during testing. For the UM8070, we set Energy Saving to 'Off,' and from the Picture menu we disabled Eye Comfort mode. You should adjust these settings to your preference though.

For SDR content, there are 10 preset picture modes. We recommend choosing the 'ISF Expert(Dark Room)' picture mode, as it is the most accurate one out of the box, and allows for the most customization. If you watch in a brighter room, 'isf Expert (Bright Room)' is almost as accurate.

We recommend setting the Contrast to '80', Sharpness at '0', Color at '50,' and Tint at '0'.

To adjust the TV's luminosity, you should adjust the Backlight setting depending on your specific viewing conditions. Changing this setting does not have any impact on the overall picture quality. The Brightness setting adjusts the image itself, and not the TV's luminosity. We usually recommend leaving this at '50'.

In the Expert Controls tab, we left Dynamic Contrast and Super Resolution off for most of our testing. We left the Color Gamut set to 'Auto,' so the UM8070 will choose the proper color gamut depending on the content. We set the Gamma to 2.2, as that is our target gamma. We chose the 'Warm 2' Color Temperature, which was the default for some picture modes.

HDR is automatically enabled for the native apps. Once you start playing HDR content, some of the settings change automatically, including Backlight, which increases to '100'. We recommend leaving these settings to their default settings in HDR.

For HDR to work from external devices, the Ultra HD Deep Color option usually has to be enabled from the 'Additional Settings' menu for the input you are using. Older devices may have compatibility issues if this option is left enabled, so it is recommended to only enable this setting for devices that require it.

If you find HDR content too dim you can try setting Dynamic Tone Mapping to 'On' and adjusting the Dynamic Contrast to 'High' which increases the brightness the most, and extremely dark scenes are brightened a bit.

Although we disable most motion enhancing functions for most of our tests, you should adjust these to whatever looks best for you. Some settings, like motion interpolation settings, may need to be adjusted depending on the specific content you are watching.

Although we usually leave these settings disabled during testing, you should adjust these settings to your liking, as different people prefer different levels of motion interpolation. If you want to enable motion interpolation, set TruMotion to 'User', and adjust the De-Judder slider for interpolation up to 60fps and then the De-Blur slider to interpolate up to 120fps.

The LG UM8070 is able to remove judder only from 24p sources. To do so, simply enable the Real Cinema setting from the 'Picture Mode Settings' menu. If you want to remove Judder from a 60i source like a cable box, then you must also set TruMotion to 'User', and adjust the De-Judder and De-Blur sliders to '0'.

From the base SDR and HDR settings, very few changes are required for a great gaming experience. The UM8070 should automatically switch to the 'Game' Picture Mode when it detects a game is being played, and switch out of it when you stop playing.

For HDR Gaming, it is recommended to enable Ultra HD Deep Color for the port you are using, otherwise, you might have some issues. If Instant Game Response is enabled, the TV should do this automatically.

For an optimal PC gaming experience and for proper chroma 4:4:4 support, it is important to set the input label to 'PC' for the HDMI port you are using. Once you have set the label, it is recommended to reapply our base SDR or HDR settings, as the picture modes change when you set the label. This can be done from the new 'Home Dashboard' menu. Depending on the format you are sending, it might also be necessary to enable the Ultra HD Deep Color setting for the port you are using.
