LG rolls out Dolby Vision 120Hz update for 2021 OLED TVs
And with that said, the 2020 models will follow as well. The update will come later to 2020 OLED and possibly more models.
As promised, LG is bringing enhanced Dolby Vision gaming support to its OLED TVs in preparation for the launch of Dolby Vision games on Xbox. LG Korea stated that starting tomorrow, June 23, it will start a gradual rollout of firmware version 3.15.27 for the C1 and G1 2021 OLED models. The update will enable the TVs to receive and process Dolby Vision signals at up to 4K 120Hz. The firmware will also include new color options (purple, orange, green) for the Game Optimizer menu, a new Game Dashboard menu at the bottom of the screen, webOS 6.0 performance optimizations, and new Gallery features. In addition, C1 and G1 owners will no longer have to manually switch between having AMD FreeSync and Dolby Vision enabled. Following the update, you can have both enabled at the same time. The company added that it will soon, hopefully within a month, make similar firmware available in beta for some of the other 2021 models. A full list of models was not provided. Customers can contact their local LG office if they want the beta firmware before the public release.
LG Korea confirmed that support for Dolby Vision at 4K 120Hz is also coming to the CX and GX OLED models as well as some other 2020 models. This firmware is currently in testing. The company said that it expects to have beta firmware available for 2020 models before Dolby Vision games are made available on Xbox. Microsoft has not announced a launch date for Dolby Vision gaming. Lastly, LG said that it is "looking into" the possibility of supporting Dolby Vision at 4K 120Hz on 2019 models such as C9.

Yes! I own the C9 and CX. Many of us were concerned that LG would leave 2019 and 2020 televisions behind. The C9 and CX are more than capable of handling this enhanced feature. The rumor is that the older models will see this around July or August.
The July and August dates are indeed rumors. I am concerned about the C9. What's sad is that the C9 has hardware features that the later models don't have. Many argue they're useless but hey, 48gb HDMI 2.1 ports and DTSX is still cool to have. I wish it had some usefulness though. Lol!
DTS is great especially if you have an HTPC attached directly to the TV, and send the audio back to a good soundbar/AVR via eARC.

You are absolutely right. I'm still a Blu-Ray guy. In my opinion DTS is more articulate but Dolby Atmos is more immersive. I'm not an Audiophile but am I wrong here?

In my opinion, both dolby atmos ( the core encoding even without the tons of speakers ) and DTS-HD-master-audio are way better than the standard dolby and dts as sound quality and bitrate. my impression is that they are comparable as quality, the difference is done by the people that create the soundtrack.

Sweet, I ordered a 48" C1 OLED last week. Wish it would hurry up and get here
