“I know this tv supports Dolby Vision and 4K/120Hz. But does this TV support using Dolby Vision @ 4K/120Hz or only 4K/60Hz like most other tv's? I want to use my Xbox Series X on it with Dolby Vision for gaming.”

According to the review at https://www.digitaltrends.com/tv-reviews/tcl-8k-6-series-r648-hdr-tv-review/: "Using an Xbox Series X dashboard, I was able to confirm that the R648 can deliver 4K120/Hz and 8K/60Hz gaming with a variable refresh rate (VRR), auto low latency mode (ALLM), and HDR, all at the same time. Like most TVs, 4K /20Hz gaming in Dolby Vision is not available." I think that last sentence is a typo and means 4K/120Hz, not 4K/20Hz.
