Wait, is that why I can’t do 4k144 on my desktop?! I never tried switching between HDMI/DP for that because they’re both capable of the bandwidth needed as far as the spec goes - I thought the issue was Gnome or something

    Likely, but DP is still superior to even the latest HDMI standards, so I'd choose it over HDMI whenever that's an option.

    I used to use it before the HDMI spec caught up, but they both now offered the same features for me (or so I thought) and the HDMI 2.1 cables I’ve got were thinner/easier to manage and hide so I swapped it out. I’m definitely gonna experiment later today and see if that’s indeed the issue, gonna be frustrating if it’s just patent/copyright garbage once again worsening user experience

    Update: For anyone wondering, this was indeed the issue and I’m able to run 4k144 perfectly over DP. I really didn’t even consider that being the problem until now given the spec parity, very dumb move from the HDMI forum

    The DRM and licensing built into HDMI is a massive con either way. Not to mention DP connectors are far more robust than HDMI - I've had quite a few HDMI cables and ports just bend/break with minimal use. Fiddled with just as many DP cables and never had a port or connector get loose or break. I'd probably choose DP even if its standards were lagging behind HDMI's.
