These are not enforced, but they are encouraged.
Rules:
We need to normalize this kind of headline:
"The HDMI Forum, whatever the fuck that means, refuses to support open source software development."
I'm not fully up-to-date with bleeding edge display technologies but is there any reason that a passive DP to HDMI adapter couldn't easily solve this issue? And would it cause Valve any strife to include one in the box?
Passive DP-to-HDMI adapters only work if the device on the Displayport end supports Dual-Mode, i.e. using the Displayport to send an HDMI signal. They often do, but it would require the same driver support for HDMI 2.1. So this would require an active adapter.
Bother 😒
With TVs starting to get USB-C inputs, which are displayport under the hood, hopefully HDMI fucks off.
Ballparking but it will likely take closer to a decade than not for that to actually happen... and I am still not optimistic. And there are actually plenty of reasons to NOT want any kind of bi-directional data transfer between your device and the TV that gets updated to push more and more ads to you every single week.
The reason HDMI is so successful is that the plug itself has not (meaningfully?) changed in closer to 20 years than not. You want to dig out that PS3 and play some Armored Core 4 on the brand new 8k TV you just bought? You can. With no need for extra converters (and that TV will gladly upscale and motion smooth everything...).
Which has added benefits because "enthusiasts" tend to have an AV receiver in between.
The only way USB C becomes a primary for televisions (since display port and usb c are arguably already the joint primary for computer monitors) is if EVERY other device migrates. Otherwise? Your new TV doesn't work with the PS5 that Jimmy is still using to watch NFL every week.
USB-C adapters for absolutely everything are thankfully quite common now thanks to the laptop/dock industry.
USB-C probably cannot replace either, because the unmating force is too light. A typical HDMI or DisplayPort cable is much thicker, longer and hence heavier than a typical USB-C cable (even those specced to carry high bandwidth, like a thunderbolt cable) because they need better shielding to carry high bandwidth signals long distances - it's not unusual to need to route HDMI several metres (but USB-C cables that long are unusual because of the different purposes)
For TVs and such it's useful to have the inputs connect vertically, so that they don't stick out the back of the device and cause problems pushing it against a wall. Then the weight of the end of the cable is going to be trying to pull the connector out of the TV. DisplayPort connectors can have a latch to deal with this.
Of course, there a ways around this: a new connector, for example. But it does mean that you can't just leverage the existing pool of USB-C connectors and cables to make this ubiquitous.
To mention, this is also a problem with HDMI (but not DP).
But just have the usb-c insert top down instead of bottom up, include room for a small loop and cable retention to ensure slack doesnt put pressure on the port. This easily allows for fixed connections with usb-c.
There are also side-screw locking connectors for usb-c. With HDMI, a top-screw option was made for more fixed install scenarios. That design is ugly af and uses a massive amount more room than the usb-c screw lock approach.
DisplayPort rocks
I used to find it took forever to start showing a picture compared to HDMI on my PC. Getting a new GPU so maybe that will improve things.
Is this why DisplayPort looks better for me on Linux???
Yes. DP is the right choice for civilized people.
Yep it's pretty much better in all regards.
The only downside is no ARC support, but I suppose support for that is pretty hit or miss anyway.
HDMI needs to die.
I mean the many incarnations of usbc are slowly making headway. For better and worse.
AMD already spent a significant amount of effort implementing HDMI2.1 in their open driver in such a way that it would be compliment. The suits from HDMI consortium still said No.
https://www.phoronix.com/news/HDMI-2.1-OSS-Rejected
AMD Linux engineers have spent months working with their legal team and evaluating all HDMI features to determine if/how they can be exposed in their open-source driver. AMD had code working internally and then the past few months were waiting on approval from the HDMI Forum... Sadly, the HDMI Forum has turned down AMD's request for open-source driver support.
AMD Linux engineer Alex Deucher commented on the ticket:
"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."
I hated HMDI when it came out, and I continue to hate it.
Fuck HDCP.
I'm honestly surprised TV OEMs haven't bothered to at least try throwing in DisplayPort, especially during the period of time it far exceeded the highest possible quality on HDMI.
HDMI is just the last hardware standard created from the ashes of the format wars that has no practical place anymore. It only exists to collect hostage licensing fees.
Tv oems are the ones that set up the hdmi club. They want the content encrypted with drm, from transit, to your pc, to your cable, to your screen. Look up the analog hole. This battle has been going on for 20 years. Share this with interested people.
HDCP (the DRM HDMI uses) is interface-agnostic though? It works over DisplayPort, heck it even works over DVI. I think that makes your argument about DRM fall apart, though TV OEMs did indeed promote the adoption of HDMI.
I don't know why they'd think I'd capture 600MB/s of uncompressed video though.
Since the torrent sites are crammed with full quality 4k Bluray remuxes and WebDLs direct from Amazon, there's clearly easier and better ways of doing this than putting encryption in a cable.
I don’t know why they’d think I’d capture 600MB/s of uncompressed video though.
Pirating live streams of sport event, which is a huge business.
Capitalism is so cool dude I love having inferior transit of 1s and 0s because some group of leeches in California own the shape that those 1s and 0s pass through
governments should start cracking down on codecs. tf are dipshits allowed to hold standards hostage?
They really just need to demand that open formats are implemented in parallel with any proprietary ones, with no artificial feature/performance disparity allowed.
That kills any incentive to keep the proprietary ones locked down because eventually the open formats will be available throughout the ecosystem and users will have devices with support in the entire pipeline. Then users will simply no longer want to deal with the locked down formats for long and nobody will want to sell them.
Proprietary formats should be illegal. Consumers are idiots, marketing will convince them to support proprietary, and regulatory capture will compromise any attempt to stop disparity
It pisses me off that you gotta pay so much money to look at the official ISO 8601.
I really wish I could find a TV within my desired specs that had DisplayPort. We will buy a Steam Machine to use it in place of our docked Steam Deck in the living room, so being able to use DP would be amazing.
Adapting DisplayPort to HDMI with minimal quality loss is child's play. It's the other way around that's misery.
Any cheap adapter cable that supports DisplayPort In to HDMI Out should be perfectly fine.
Fuck HDMI! All my homies use DisplayPort.
Unfortunately my TV is not one of your homies.
The main feature of Hdmi has always been DRM.
Pfft. People using monitors or tvs. I just plug into it and play it in my head.
That's what the Steam Frame is for.
