Oh, I know this one. It was recently on the HN front page. Open source software stacks are locked out of high end pixel clocks.
Because HDMI 2.1 uses a proprietary protocol that's not implemented in any free OS[0]. If you want to use HDMI 2.1 features right now, your only option is to use a non-free OS like Windows or MacOS.
