The LG C1 & G1 OLED TVs get a new Game Dashboard following the rollout of firmware update 03.15.27, in addition to 4K 120Hz Dolby Vision support with ALLM correctly defaulting to [Game Optimiser] mode, not to mention improved UI responsiveness for WebOS 6.0.
LG has confirmed that the company is working on a beta firmware update for some 2020 OLED TVs including the CX and GX, which should be available soon (at least one month away) to be requested on demand by calling LG's customer support in your own country.
The South Korean brand could not provide a comment to us regarding adding 4K 120Hz Dolby Vision support to the C9, but other publications have said that LG is looking into the matter.
