Appreciate the info. I was a little too broad with the term “monitor”; I am using an LG C2 TV (with HDMI 2.1, but no USB-C input). There will be situations where I would take advantage of USB-C video out as well though, so that’s good to know.
It would be nice to have some type of official confirmation but I’m certainly okay with holding a reservation in the meantime based on what’s been mentioned here. It sounds like HDMI 2.1 is “technically” possible in the future with an updated HDMI expansion card.
