HDMI 2.1 carries more bandwidth than DisplayPort 1.4. Plenty of GPU/monitors have that port arrangement, as recent as Nvidia's RTX 40 Series.

Yeah but this is for amdgpu and they had DP2.1 support for a while now.

That doesn't help when the monitors don't have DP2.1 support.

I havent seen a monitor (besides tvs) that has HDMI2.1 but not DP2.1

		I can tell you mine does: a Corsair XENEON 27QHD240. Or the somewhat popular and badly named Acer Nitro XV275K P5biipruzx I'd say it's usual for displays released 2-5 years old. HDMI 2.1 got somewhat quick monitor support for consoles, but search for "first DP2.1 monitor" gets results from 2024

		And that parenthetical is exactly why people care. TVs.
