HDMI Forum is unwilling to disclose the 2.1 specification for open-source (Linux): according to AMD, they had submitted a functional, HDMI 2.1-compatible driver [for linux?], which the Forum rejected. (www.heise.de)

I do not really have a body for this. I was not aware that this is a thing and still feel like this is bs, but maybe there is an actual explanation for HDMI Forum's decision that I am missing.

Time to kill HDMI with USB 4/TB bring those cost way down.

Display Port would be better suited to do all of those things.

Usb-c supports DisplayPort! Long live open standards!

[-] Fiery@lemmy.dbzer0.com 7 points 2 days ago

Except DisplayPort has high data transfer speed requirements and many cables that fit the nice reversible ports do not support it.

We really do need better cable identification standards for usb-c. Like electrical and cat cables have had this better addressed for a while now.

[-] gnuplusmatt@reddthat.com 6 points 2 days ago

are USB-C ports that do display using displayport standards to do it anyway?

[-] justme@lemmy.dbzer0.com 5 points 2 days ago

Yes, they do. You just need a fitting cable, which supports the bandwidth.

Normalize USB-c with screws and we have a deal.

[-] JackbyDev@programming.dev 3 points 2 days ago

HDMI does not have screws.

[-] Hupf@feddit.org 8 points 2 days ago

Yeah, it's a pretty bad connector.

[-] ABetterTomorrow@sh.itjust.works 2 points 2 days ago

With cinema camera accessories, we have these “locking” USB C plugs. They have these notches that help stay in the port. I say it’s about 2.5x more firm and doesn’t wiggle much.

Like the old USB micros sort of?

[-] ABetterTomorrow@sh.itjust.works 2 points 2 days ago

I think the micro B had hooks on them? Are you talking about that? The USB C plugs I’m referring to had these dimples on the skinny side and the bumps are in the port.
