The HDMI Forum has rejected our proposal unfortunately. At this time an open source HDMI 2.1 implementation is not possible without running afoul of the HDMI Forum requirements.

Why did HDMI succeed over display port? Always the same problems with closed source.
Because the movie studio execs like their hdcp drm
Which in a lot of cases can be easily removed with adding an HDMI splitter in between. Fuck DRM!
Which is funny because of how easy it is to circumvent

I just hate how my monitor came with a HDMI cable

HDMI did have a head start, but nowadays, the answer is money. As usual.
It’s an older interface than DP and has “better” support for audio (I.e. all of those proprietary passthrough audio formats that home theater setups support) so it became dominant in TVs. Monitors are still DP first but likely have a HDMI port as well.
Most modern monitors have a single displayport, and then a small army of HDMIs.
That kind of makes sense though. I figure they assume you’ll have one computer hooked up and then a bunch of consumer devices that all use HDMI. And if you need a second computer hooked up you can also use HDMI if needed. Probably makes the most sense to the most people as having more DP in place of HDMI would just mean the average user couldn’t hook up as many devices since (almost?) no consumer devices use DP unfortunately.
You forget every desktop GPU having 3 DisplayPorts and only 1 HDMI, and USB C supporting DisplayPort?
Is display port still open source? I thought something happened.
In my experience, its cause monitors are already over priced, and adding a display port to it seems to add at least another 100 on top of that.
Which is why I prefer HDMI. Less cable headache too, since I only have to keep one type of cable in stock and so i can easily switch for testing/diagnostics/layout change purposes.
I… don’t think display ports add 100 on top of the price. Do you have a source for it that its so much more expensive?
I didnt say they did, I said they seem to, since in my experience every monitor that had similar spec, but had a display port, was about 100 dollars on top of whatever the hdmi only one had.
To hell with proprietary, binary blobs.
If I was AMD I’d tell them to suck my ass and reverse engineer that shit anyway. Unfortunately I’m not AMD, lol.
They don’t need to RE it; they have access to the full spec and everything for their Windows drivers anyways. They’d open themselves up for litigation if they implemented this behind the forum’s back though and that’s something AMD (understandably) simply won’t do.
They could hire dedicated teams that has no access to the full spec to RE it and it should be above board, as long as it’s done right ofc.
Hopefully AMD start doing what Intel does and including a DP -> HDMI 2.1 converter in the card itself. There are already third party adapters that work reasonably well with existing AMD GPUs, especially on Linux. If they had their own implementation they could iron out the quirks and driver issues and get something that should be equivalent to real HDMI 2.1.
