Fuck hdmi
HDMI requires a license cost, DisplayPort is free.
What advantage does HDMI hold over DisplayPort?
It makes them money.
The HDCP encryption is why it’s used.
No real technical advantage; it’s just owned by the same shitbags that dominate the TV market, so it’s the only way to connect to a lot of consumer living-room displays
This is the problem. I would switch to DP instantly but my TV only has HDMI ports.
There are DisplayPort to HDMI converters available
Pretty sure DRMed content refuses to play on those.

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.
Latency, desync, probably can’t do full 4k/120… just because something exists doesn’t mean it’s a viable solution.

Display port to HDMI cables are pretty good
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.
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?
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 know what HID is, but CEC lets you control Kodi with the TV remote.
My guess is TV compatibility. The steam machine is intended as a living room PC, connected to your TV. Most TVs only have HDMI, no DP.
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.
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.
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 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.
The only down side is DP Alt mode is optional and must be enabled and supported by the internal controller and system. In order to do that, you might as well just go full DP at that point and somehow I don’t think the manufacturers are gonna spend more money on that. Most likely the USB-C port only supports a mass storage class device.
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.
I’m not sure where I got this idea, but I thought it was because Display Port doesn’t carry audio, and a single-cable solution was more appealing.
But apparently Display Port also supports audio, just none of my devices seem to recognize it…?
Apparently the only advantage of HDMI is ARC (Audio Return Channel), allowing devices to send audio back to the video source, which might be useful in some home theater setups.
And cec. Idk what arc is but I use cec daily.
ARC lets you connect your speakers to your TV via HDMI, while also letting your TV control the speakers via CEC. The downside is that it takes up an HDMI port, and they only put like 2 of them on modern TVs.
I’m pretty sure Display Port supports CEC (pin 14)
I ruined my audio ports on my computer and now run my speakers through my monitor using DP, it works great!
Ohh TIL, thanks! I could count the times I needed the TV to send audio back to the home theater, like if I want to watch open channels or something.
I think we could live without it, just plug an audio cable or something, fuck hdmi.
Wow I always assumed the same thing lol
Omg is this seriously it??
I don’t think you can send audio over DisplayPort
Funny, I have done it for years at home, I guess I am just confused
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.
HDCP?
Displayport needs to start showing up on TVs and eventually get standards for stuff like eARC and HDMI CEC
TV OEMs are apparently part of the HDMI forum and therefore complicit.
We need EU regulation if we want to have this.
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.
DisplayPort for the win
Sincerely! As someone who dislikes DisplayPort, moves like that makes me want to use it over HDMI.
Hmm, that’s a new one for me. Why the dislike for DisplayPort?
I had many problems with it in the past. It has been behaving well with me in the last 1-2 years though
“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.
At least one person got the joke. 😁
It exists. It’s Display Port.
The use case of “make a shit ton of money licensing a proprietary standard” is kind of mutually exclusive with other use cases. It would be hard to cover.
At the time, there were too many standards. But looking back from today, we see that standardization does eventually occur, it just takes time.
It already comes with DP 1.4. enough for me
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.
