LG C1 XSX 4k 120hz Dolby vision no longer showing in tv details screen.

I just started seeing this same warning on my LG C1 as well. Before this most recent update, I also had full green checkboxes down this screen.

I haven’t noticed any increased input latency thankfully. As long as game mode is enabled on my TV, Dolby Vision at 4K 120Hz still feels almost instantaneous.

Yes, please bring Dolby Vision support to the Xbox 4k Blu-ray player! I have a vast collection of 4k Blu-Rays and a tv that supports Dolby Vision (LG C9).

No, unfortunately, one cannot speak of clarity in this case, because I have experienced the exact opposite case.

I own the LG C1 and the LG C2, and the handshake problems have NEVER occurred in over a year of use on the C1! Instead, however, they keep coming back with the C2 on the same Xbox Series X console. When switching this console back to the C1, the same picture again, NEVER! LG C1 and LG C2 both support Dolby Vision (for gaming). Before testing the LG C2 with one / my Series X, I had never heard of the handshake issue with Dolby Vision. Besides, the LG C2 works very well, but the Dolby Vision handshake in games can hardly be tested on other devices, because the PS5 does not support this feature and other devices are at least unknown to me.

That's coincidental then. As per the last post, it's only started happening since LGs last update! No problems whatsoever prior to that. It all points to that if anything. Plus only when game optimiser is turned on with 4K. Even in the xbox settings for TV details it even says your TV supports 4k 120hz dolby vision gaming but you may experience issues when this is switched on etc... That didn't come up before the update on the TV. However there were both an LG update and xbox update recently so clearly they haven't merged well at all. Thanks for the reply tho buddy 👍
