Performing this task might seem difficult. But if you use a guide ( as our article), you can get the right HDR settings within minutes. Now here are the HDR Settings needed for the C1, CX, and other similar TV sets.

LG TV HDR Settings Guide

Now here are the LG TV HDR settings for the above TV sets. Although we have listed some of these settings, we recommend that you go check the owner’s manual that came with your TV. You can also contact LG customer service for extra advice.

LG TV HDR Settings for LG C1

If you are using this TV, you might not have to bother with the HDR Settings. After all, this TV automatically adjusts these settings itself. Overall, we recommend that you keep these settings on default.

But if you plan to use external devices with your LG TV, it would help if you switched on the HDMI Deep Color option. Moreover, if setting the HDR offers dimmer images, you could turn on Dynamic Tone Mapping and Auto Dynamic Contrast.

LG TV HDR Settings for CX

As with the C1, the LG CX TV automatically adjusts the HDR Settings for apps and HDR content. So instead of thinking of tweaking the values, you should allow the TV to do all the work. But if you are playing content from an external HDR device with the TV, you can enable the Ultra HD Color.

Do your HDR images look dim? If yes, head to the Settings Menu and switch Dynamic Tone Mapping. Then increase the Dynamic Contrast to your preference.

LG TV HDR Settings for LG C9

Supposing you are using the LG C9 TV, you should not have to set the HDR settings. When it comes down to it, this TV adjusts the HDR automatically. So it would help if you stuck to the default settings.

Sometimes, the automatic settings might not be bright enough. If you have this problem, turn up the Dynamic Contrast and set the Dynamic Tone Mapping. For HDR Gaming, turn up Ultra HD Deep Color.

LG TV HDR Settings for LG C2

If you are using the LG C2, leave the HDR settings on default. But you can take the Picture Mode at Cinema. But when it comes to playing HDR Content from external devices, head to the HDMI Deep Color – 4K. Then enhance the brightness by choosing Dynamic Tone Mapping and Auto Dynamic Contrast.
