Somebody replied to other comment, but it seems like hdmi allows audio to be sent back, like, if you wanted your screen to send audio to the computer… which would be weird in most PC scenarios, but not so much on TVs.

I haveb’t looked into this particular group, but usually it’s patents. Someone owns a patent for the tech required to implement the standard, and they “license” it out to anyone who wants to implement that standard. Obviously, they won’t agree to terms that hurt their ability to collect rent on their patent. Qualcomm is famously guilty of this in the modem space.

Does that seem stupid, to adopt an industry standard that requires patented technology to implement? That’s because it is, and were we a sane society we would invalidate any patents that become an industry standard, but we’re a bunch of idiots with a billionaire cuck fetish.

Wow I always assumed the same thing lol

I remember when HDMI came out and then DP.

I wish I knew what was actually going on at the time with regards to licensing, I just knew they both worked and didn’t really pay much attention to things. Sometimes I’d use DP sometimes HDMI.

If I’d known, I definitely would have made a more concerted effort to support DP when it could have made a bigger difference.

My understanding is it’s not even a licensing issue. The HDMI consortium won’t let you include features from 2.1 and 2.2 in an open source driver. it sounds like Valve would be willing to pay, but they’d have to include a closed source driver for the video card.

HDMI has always sucked. I used DVI for the longest time, because HDMI couldn’t push enough pixels to a 1920x1200 display (topped out at 1080p for the longest time). Then jumped straight to display port when I finally got a 4k monitor.

HDMI was always 4-5 years behind other contemporary protocols, and for your trouble, you also got a stack of proprietary bullshit to go with it.

The HDMI founders were Hitachi, Matsushita (now Panasonic), Maxell, Philips, Silicon Image (now Lattice Semiconductor), Sony, Thomson (now Vantiva), and Toshiba.[3] Intel contributed the HDCP copy protection system.[4] The new format won the support of motion picture studios Fox, Universal, Warner Bros. and Disney, along with content distributors DirecTV, EchoStar (Dish Network) and CableLabs.[2]

While Sony is a technology company, they’re also a very sue happy IP holder through Sony pictures and Playstation.

Sony continues to be a major player on the HDMI forum.

Quit posting ancap propaganda.

The way this sort of thing would actually improve is by government regulation.

Fine. then use a Roku or Apple TV or whatever. He literally included those.

Do they make DP support HDMI 2.1/2.2?

Rokus have the same problem regardless of form factor. But this thread is about people who want to use the Steam Machine for streaming.

Yes HDMI forum are shitbags, but there are definitely technical advantages to HDMI. Just that I can think of, DisplayPort doesn’t have ARC (audio return for sound systems), or CEC (device can turn on TV/display, TV remote can pause movie playing on console, etc) and the max length for a DisplayPort cable is no more than 3 meters before you have to go to expensive active cables. Most of these are easy to work around for most PC setups, but if Valve wants the gabecube to easily fit into living room/TV setups, it does present a challenge.

Most people who want plug and play probably don’t know what VRR is.

Heck I don’t fully remember it and I actually learned why it’s nice and would want it.

That’s still a licensing issue: you’re not allowed to license from the HDMI consortium and then freely sublicense to all your users, which is what open source requires. Hopefully this eventually concludes in the end of relevance for HDMI and we can have a freer, and just better ecosystem in general.

That one I linked does HDMI 2.1
I haven’t seen any that claim 2.2

There are also cables with DisplayPort on one end and HDMI on the other. No seperate adapter

All of these supposed advantages are solved by USB-C though. Even the length is higher (5m, I believe). I’d be fine if the DisplayPort connector is gone, but the actual standard is just better for most purposes.

I just don’t trust the claims. Looks like mixed reviews on 2.1 features working.

I wonder what one should actually expect to work in a passive cable/adapter.

Length matters. Off the top of my head I think the spec is for 16’ max. If you’re dasy changing a pair of 10’+ cables on an adapter like that, you might run into problems.

I don’t see “relevance for HDMI” ending anytime soon. Tell me how easy it is to find a TV with DP inputs. Nearly 99% of consumer gear uses HDMI.

As end consumers we individually have no power to affect the types of products that are offered. What am I supposed to do? Find me a TV that supports DisplayPort
