The HDMI Forum, responsible for the HDMI specification, continues to stonewall open source. Valve's Steam Machine theoretically supports HDMI 2.1, but the mini-PC is software-limited to HDMI 2.0. As a result, more than 60 frames per second at 4K resolution are only possible with limitations.

Are people just forgetting it has a displayport also? Just ignore HDMI, they got greedy, onto the rubbish pile they go.

    The people who block HDMI for Linux are also the people who make TVs and other media stuff. So you may not be able to use displayport or hdmi just because some rich people decided so to make more profit.

    This is what I said the other day about this issue. Good luck finding a decent tv with display port! Those fuckers are rare and expensive!

    They are called monitors, and yeah expensive but then you don't get a "Smart TV" with tracking and bullshit.

    Nor do you get TV tuners. While most geeks probably couldn’t care less, any associated family do prefer to watch Great British Bake-off as it airs.

    Just told my elderly aunt to not buy a smart tv today!

    But do they make 40ish+ monitors?

    They do, but they much more expensive than a smart TV, even though they have less components.. Because a Smart TV is sold for less because its providing the vendor access to you as a product to all of their 3rd party partners.

    Basically no modern TV has displayport except for few that come with USB-C

    DisplayPort to HDMI adapters are quite cheap and don't add latency.

    Aside from practicality, might there be something that gets lost if you do this? (e.g. worse frame rate, quality or sth. else)

    No, DisplayPort, DVI-D and HDMI use fundamentally the same protocol, HDMI just adds DRM which requires active adapters when one plugs in a HDMI source into a DisplayPort sink. DisplayPort to HDMI conversions are completely lossless and don't add latency AFAIK.

    The problem is that many TVs have HDMI, but no DP.

    Then buy a DP to HDMI 2.1 dongle

    Wouldn't an HDMI to DP cable work then?

    That's not really how it works given that so many devices have HDMI ports.

    If we expect to make hardware devices that are generally compatible with interfaces non-technical users use, then excluding an entire class of common modern interface spec isn't a great choice.

    It'll be fine for now but as the specs bump up inversion and HDMI changes over time is just going to get worse

    but as the specs bump

    Eh, 4k is already at the point of diminishing returns. There are 8k displays for a while now, but nobody buys them.

    Rather, create 5k please.

    I wish game devs knew how to optimize for storage better. Let me install HD instead of 4k games if I choose. I do the same thing for anime series because HD barely takes up any space at all.
