LG SM9000 Calibration Settings

The video demonstrates the settings for the LG B8/C8. Although it's not exactly the same as this TV, it will still give you a pretty good idea of what each menu item does. We will update it with a more current settings video if we make one.
For additional settings information, please consult the Common Problems and How to Calibrate pages.

We used the following calibration settings to review the LG 55" SM9000 (55SM9000), and we expect them to be valid for the 65" model (65SM9000), 75" model (75SM9000), and 86" model (86SM9000). 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.

General Settings

Eco Settings

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 SM9000, we set Energy Saving to 'Off', and from the Picture menu we set AI Picture to 'Off', and we also disabled Eye Comfort mode. You should adjust these settings to your preference.


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 '90', 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'.

Expert Controls

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 SM9000 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.

We left Noise Reduction, MPEG Noise Reduction, and Smooth Gradation disabled for our testing. If you notice a lot of noise or banding in your content, these features can help reduce it, but they can also cause a loss of fine details.


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.

Dolby Vision

The SM9000 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.

How to make HDR Brighter


If you find HDR content too dim, there are a few things you can try. Adjusting the Dynamic Contrast setting to 'High' increases the brightness the most.

You can also try enabling Dynamic Tone Mapping. Although we don't normally recommend this feature, it analyzes each frame to try and determine the optimal tone mapping. This can make some bright scenes brighter, but also some dark scenes darker, which can cause some loss of detail. The image on the side shows the EOTF of the TV with both settings applied.
Dynamic Tone Mapping isn't available with Dolby Vision content, as Dolby Vision already has dynamic tone mapping, thanks to the use of dynamic metadata.

Motion Settings

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.

Motion Interpolation

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.

Black Frame Insertion (BFI)

The Motion Pro setting enables the SM9000's black frame insertion (BFI) feature. Enabling it activates the BFI feature at 60 Hz, which may bother some people.

Judder Settings

The LG SM9000 is able to remove judder from all sources. To do so, enable the Real Cinema setting from the 'Picture Mode Settings' menu and change the Trumotion setting to 'User' with the De-Judder and De-Blur set to '0'.


From the base SDR and HDR settings, very few changes are required for a great gaming experience. The SM9000 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 SM9000 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. Instant Game Response, however, works only with compatible devices like the Xbox One. If your device is not supported or you wish to enable 'Game' mode just once, you can do so from the Picture Mode menu by selecting the 'Game' option.

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.

PC Gaming/Desktop use

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 Ultra HD Deep Color setting for the port you are using.

White Balance Settings

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.
