I bought an LG C3 in 2023 and since then, I never updated it. I decide to updated it like 2 weeks ago, and, after the update, I noticed that, if I set HDMI Deep Color to 4k, almost all the clarity settings are grayed out, including the TrueMotion I’m interested in (I like it on Cinematic Movement).

Before the update there wasn’t this issue. What can I do?

I tried:

• changing the cable
• change the input type to streaming box or Blu-ray player
• reset the TV

Info:

• I’m using the TV connect to a pc (with Linux if that matters);
• OS version: 33.22.95
