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 😒
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
I so wish they only gave a complementary display cable and not an HDMI.
They do. But a lot of displays don't support DP so HDMI is there for them. If you have a capable TV, then there is no issue.
Sorry, brainfarted, I meant cable not port.
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.
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.

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."
As a bazzite user, with it connected to my living room TV that only has HDMI ports, yeah this was obviously why Valve said 2.1 isn’t supported at the steam machine reveal.
I have a HDMI splitter, like a 5 input 1 output thing. I have not used it in awhile. Does HDMI pass through the DRM or is the DRM in the splitter?
The source device (the steam machine in this case) will check with the display and see what the highest HDMI standard they both support is. It may also check if your splitter supports it, but I suspect the splitter is just a passthrough device.
I figured. I also used the wrong term, it is a switch.
I know some HDMI switches will, some won't and others will strip the DRM and let the picture go through. I had to try several ones to get a conference room TV to work with a HDMI auto switch. Funny it was the cheaper model on Amazon lol
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.

With TVs starting to get USB-C inputs, which are displayport under the hood, hopefully HDMI fucks off.
