Valve Responds To Steam Machine's HDMI 2.1 Display Support Controversy [HW support is there, but "The HDMI forum" doesn’t allow with OpenSource drivers]
-
The movie studios. As the person above said, the HDMI consortium (owned by movie studios) is focused on protecting their members IP rights from pirates. HDMI has built in DRM, that could be removed from an open source driver.
so what you’re saying is we need to make hdmi driver patches to allow direct file saving from video streams?

Well, one of the master keys leaked about 15 years back. A researcher posted a paper back in 2003 or so that outlined a method of finding a master key that was likely used by the people who made the release. It was a fun time to be on the internet, the people came together and said, yeah fuck those corpos and everyone reposted the key to every form of social media possible. I knew someone with the key tattooed on their arm (as part of their piracy themed artwork, I used to have pictures)
Now, that particular master key was patched out with a compatibility breaking upgrade, specifically 2.1 of the standard, which was proven to be broken in 2012, but there was less coming together to share it the second time, or the third for 2.2 of the standard.
But yes, if you wanted to code your own, you easily could. Just don’t share it or the sue happy corpos will come knocking.

I’m not sure why people are so upset.
It’s a little annoying sure, but don’t these work?It has displayport already, the hdmi concerns are regarding its utility with a television.

️ Well ️ I ️ don’t ️ care ️️ Well ️ I ️ don’t ️ care ️Random clips on the web are DRMed these days, like news articles with an embedded video. Many CMSes just DRM all clips. Totally BS but I’ve seen the video frame staying black on a bunch of sites now.

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.
The signal quality can be flaky. You need a good, short, hdmi “8k” cable for it to work reliably.

Then I won’t watch those, simple as. Plus, I’ve been running LibreWolf for like a year, whick blocks all DRM by default, and never in my life did I have issues playing a video. Even live videos from TV channels work 50% of the time.
Plex tv is the only one that seemingly requires DRM from when I looked into it. Didn’t decide to use it specifically for that reason.

Doesn’t change facts for millions of others.

HDMI requires a license cost, DisplayPort is free.
What advantage does HDMI hold over DisplayPort?
The HDCP encryption is why it’s used.
-
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.
Cec over USBC?

Huh I though that was hd-dvd

Latency, desync, probably can’t do full 4k/120… just because something exists doesn’t mean it’s a viable solution.
“DisplayPort generally offers better support for high refresh rates and adaptive sync technologies, which can help reduce desync issues in gaming. HDMI can also support variable refresh rates, but it may not perform as well in high-end gaming setups compared to DisplayPort.”
“DisplayPort generally has lower latency compared to HDMI, especially in gaming scenarios, due to its design for high refresh rates and adaptive sync features.”
“DisplayPort generally supports higher refresh rates and resolutions, making it ideal for 4K at 120fps, especially in gaming setups. HDMI 2.1 also supports 4K at 120fps, but compatibility may vary depending on the devices used.”
Took a 1 minute search to find that out btw.

How many embedded DRM-controlled news article videos are you watching on your living room tv though? PC monitors usually have native display port nowadays, no converters or HDMI necessary.

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.
Valve should ship it as displayport internally and bundle a free HDMI adapter that they sell in the store, that way it’s all open source and the HDMI issue is taken care of in the most flippant way possible.
-
“We need to develop a one universal standard that covers everyone’s use cases.”
They did, it was displayport. HDMI actively removes features the TV makers don’t want you to have.
-
Could have been…
Both were about the same timeframe.

I think thats actually what Intel did on their A series graphics cards. Only had display port out signals but had a display port to HDMI adapter built into the board.

Yes, but that adds more cost. I don’t have any hard data on this, but it feels like their current solution works fine, since anyone using more data than 2160p60, who also won’t accept chroma subsampling, probably is already using DP. Maybe this is a direction to pressure the HDMI forum, since unlike AMD, valve’s drivers are actually open source on the majority of their users’ machines. And if things change in the future, external adapters or proprietary adapters are both solutions.

I’ve never actually used CEC, but everything I’ve seen says it’s just like a USB HID, correct? According to wikipedia, there already exist USB to CEC adapters.

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.
It’s easy to find a TV with USB-C input, though not universal. That still uses the DP protocol, and cables with different connectors on opposite ends are both cheaper and more common than those with HDMI as a result. Also, this is only even an issue if HDMI 2.0 isn’t fast enough for you, so old devices aren’t a concern.
