LG UN8500 Calibration Settings

We used the following calibration settings to review the 65 inch LG UN8500 (65UN8500PUI), and we expect them to be valid for the 75 inch (75UN8570PUC), 82 inch (82UN8570PUC), and the 86 inch (86UN8570PUC) models too. 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 this TV, we set Energy Saving to 'Off', and from the General menu we set AI Picture to 'Off', and we also disabled Eye Comfort Mode in the Picture menu. You should adjust these settings to your preference.

For SDR content, there are a whopping 10 preset picture modes. We recommend choosing the 'isf Expert (Dark Room)' Picture Mode, as it's 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 '10', 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 this TV 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. We recommend leaving these settings to their default settings in HDR.

For HDR to work from external devices, the HDMI 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's recommended to only enable this setting for devices that require it.

If you find HDR content too dim, there are a few things you can try. Set Dynamic Contrast to 'High' and Backlight to their max, and using these settings, the image is brighter as you can see the EOTF here.

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 De-Judder and De-Blur.

This TV is able to remove 24p judder from native any source, including Blu-rays and native apps. To do so, simply enable the Real Cinema setting from the 'Picture Mode Settings' menu.

From the base SDR and HDR settings, very few changes are required for a great gaming experience. It supports Auto Low Latency Mode, which is enabled by enabling Instant Game Response from the 'Additional Settings' menu. Once this setting is enabled for the input you are using, the TV 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's recommended to enable HDMI 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 proper chroma 4:4:4 support, it's important to set the input label to 'PC' for the HDMI port you are using. Once you have set the label, it's 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 HDMI Ultra HD Deep Color setting for the port you are using.
