LG NANO99 8k 2020 Calibration Settings

We used the following calibration settings to review the LG NANO99 65 inch (65NANO99UNA), and we expect them to be valid for the 75 inch model (75NANO99UNA) model 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 '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, '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 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. LED Local Dimming controls the TV's local dimming feature, and we left it at 'Medium' during testing.

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 is recommended to only enable this setting for devices that require it.

The TV supports Dolby Vision, from native apps and with most external devices. As with normal HDR content, when you start playing Dolby Vision content, some settings change automatically. We recommend leaving these settings as-is, do not copy our SDR settings over. We recommend the 'Cinema' Picture Mode, but if you find the image too dim, try 'Cinema Home'. With 'Cinema Home', we noticed some issues in dark scenes, including raised black levels, and a bright flash in some scene transitions.

If you find HDR too dim, set the Picture Mode to 'HDR Standard' with Brightness, Contrast, Dynamic Contrast, and Local Dimming at their max settings with Dynamic Tone Mapping enabled. This results in a much brighter image, as you can see in this EOTF.

However, there's a strange increase in brightness at around the 40 stimulus mark, and this coincides with when the screen appears to flicker in HDR, as explained in the Local Dimming section.

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-Blur and De-Judder sliders.

The Motion Pro setting enables the TV's Black Frame Insertion (BFI) feature. Enabling it activates the BFI feature at 60Hz, which may bother some people, but it helps reduce motion blur.

The TV can remove judder from all sources. 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. The TV is supposed to support 'Auto Low Latency Mode', which is enabled through Instant Game Response from the 'Additional Settings' menu. However, it wasn't working for us during testing, so you may have to manually switch it into 'Game' mode when gaming.

For HDR Gaming, it is recommended to set HDMI Ultra HD Deep Color to '8k' 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 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 HDMI Ultra HD Deep Color setting for the port you are using.
