LG’s 2019 OLED TVs will not receive support for the use of Dolby Vision with a video output with 4K resolution and a refresh rate of 120Hz. There was a chance that the TVs would get the option, because they do support the required bandwidth over HDMI.

The news comes out via television critic Vincent Teoh, from the YouTube channel HDTVTest. According to him, LG has finalized the list of DV 4k120 compatible models. Some newer models from 2020 and 2021 are also excluded in this area. Logically, this concerns the cheaper models, such as the BX and the A1. Teoh explains in a video what he suspects is the reason for LG to sail this course.
It was still unclear whether, for example, OLED TVs from 2019, such as the C9, would also have the option to use 4k120 with Dolby Vision. This model contains different hardware, in the form of a soc that was also in the OLED TV models of 2018 and can therefore only handle HDMI 2.0. A separate HDMI chip was added for the 2019 models to enable a bandwidth of 48Gbit/s. The CX, GX, C1 and G1 all go up to 40Gbit/s, which is sufficient for the HDMI 2.1 capacities.
4k120 with Dolby Vision is a feature currently only supported on Xbox Series X and S; and Sony only offers HDR10 in its PS5. Teoh notes in another video that the lack of no DV 4k120 on the TVs is limited by the fact that the Xbox Series X and S currently don’t have games that natively support Dolby Vision; the console converts HDR10 to DV.
