Nab yourself either a DP to HDMI 2.1 or USB-C to HDMI 2.1 box, and then update the firmware on the chipset when you get it. You'll be quite happy.

As for Dolby Vision - a few words of advice. Thus far, DV for gaming have been total rubbish on anything I've tested on either Series X or PC - even games like Halo Infinite that are suppose to use it natively, and not an auto HDR conversion. I highly recommend sticking to HDR10 for gaming, go watch Vincent @HDTVtest's videos on the topic.

For movies and tv however, DV encoding is absolutely amazing at preserving the artistic integrity and giving it that movie theater feel - however I am of the strong opinion that no Win PC application can hold a candle to running native smart apps on the TV itself, with access to low level API calls. They don't need to mess around with 3:2 pulldown, and seamlessly match the correct refresh rate for content (real 24hz for 24fps content), as well as a much more precise bfi engine. Netflix, Disney+, whatever - run it on the tv. For local media files, you can install Plex as a smart app and just setup the media server on your computer. This is also coming from a very long time user of media player classic and high end codecs. Even MadVR cannot match native app accuracy.

Do you think that will do the job?

A lot of people recommend the USB-C version, or this -> https://www.amazon.com/gp/product/B08MSWMXT4/ref=ox_sc_act_title_3?smid=A1AMUYYA3CT6HJ&psc=1&pldnSite=1

Your card definitely supports DSC, and the Apple XDR uses it... wondering if it requires a patch or custom EDID to get working on macOS?

I used a patch to get my 4K @60Hz working on my Samsung 4K monitor (as HiDPI).
