DisplayPort to HDMI converters trivially solve that. Let the TV consume HDMI all it wants while still "just" outputting DP from the computer.
It’s powered by this chipset afaik which supports vrr and hdr. https://www.connect.synaptics.com/spyder
It is also a USB-C to HDMI adapter, not a pure DP adapter. I think only the 20-series of Nvidia GPUs and maybe some of the 5000-series AMD GPUs have DP capable USB-C outputs. And apparently the M1/M2 Macs that the first article is about.
CableMatters is a good brand so if anyone could do it it'd be them, but it appears it's not quite there yet. Maybe when DP 2.0 becomes more common on GPUs it'll be a solved issue.
Based on my experience, this doesn't matter. I have a video card with no USB-C outputs. I go from full-sized DisplayPort to a female <-> female DisplayPort coupler, to this [0] bidirectional DP <-> USB-C cable, which plugs into my monitor. It works great and even does 4K 60FPS uncompressed HDR no problem.
I see no reason why you'd be unable to then slap on a female <-> female USB-C coupler and then that USB-C -> HDMI adapter.
(There's also no reason you couldn't cut out the first DP cable and coupler and plug the DP <-> USB-C cable directly into the video card. I just have very long (fiber-optic) DP cables that the second cable plugs into.)
