Sounds like hdmi Forum are a bunch of twats. Time for a new format.

We cannot have two standards, that's ridiculous! We need to develop one universal standard that covers everyone's use cases.

[–] SlopppyEngineer@lemmy.world 113 points 9 months ago* (last edited 9 months ago)

There are now three competing standards.

I know what you are referencing, but displayport already covers everybody's use cases

I’ll just pull it up on this display that’s more than 9 feet away from the source…

[–] Tattorack@lemmy.world 17 points 9 months ago

Yes, I agree. And it needs to be open bloody source!!

And what does that use? That's right it's Displayport Alternate Mode! Oh you've got Thunderbolt? Guess what, also Displayport!

Hard to find on non-pc gear, but that’s a fair point

[–] frezik@midwest.social 14 points 9 months ago (1 children)

It's usually easy enough to adapt it as needed. It can typically send signals compatible with HDMI and DVI-D just fine.

[–] zarenki@lemmy.ml 7 points 9 months ago

The passive adapters that connect to DP++ ports probably still rely on this HDMI specific driver/firmware support for these features.

USB-C display output uses the Display Port protocol

[–] ABCDE@lemmy.world 23 points 9 months ago (2 children)

Can it use others, and is there a benefit? USB C makes a lot of sense; lower material usage, small, carries data, power and connects to almost everything now.

[–] BetaDoggo_@lemmy.world 44 points 9 months ago (6 children)

I believe USB-C is the only connector supported for carrying DisplayPort signals other than DisplayPort itself.

The biggest issue with USB-C for display in my opinion is that cable specs vary so much. A cable with a type c end could carry anywhere from 60-10000MB/s and deliver anywhere from 5-240W. What's worse is that most aren't labeled, so even if you know what spec you need you're going to have a hell of a time finding it in a pile of identical black cables.

Not that I dislike USB-C. It's a great connector, but the branding of USB has always been a mess.

[–] strawberry@kbin.run 15 points 9 months ago* (last edited 9 months ago) (2 children)

would be neat to somehow have a standard color coding. kinda how USB 3 is (usually) blue, maybe there could be thin bands of color on the connector?

better yet, maybe some raised bumps so visually impaired people could feel what type it was. for example one dot is USB 2, two could be USB 3, etc

[–] Flipper@feddit.de 15 points 9 months ago (1 children)

Have you looked at the naming of the usb standards? No you havn't otherwise you wouldn't make this sensible suggestion.

[–] strawberry@kbin.run 5 points 9 months ago (4 children)

the shenenigans with USB 3 naming you mean? you're right, this would be too logical for USB lol

Please think of the shareholders... :(

[–] jaxxed@lemmy.world 4 points 9 months ago

I think that the biggest issue with dp over usbc is that people are going to try to use the same cable for 4k and large data transfers at the same time, and will then whine about weird behaviour.

[–] ABCDE@lemmy.world 2 points 9 months ago

Yep, very true. I didn't understand this until I couldn't connect my Mac to my screen via the USB C given with the computer, I had to buy another (and order it in specifically). Pick up a cable, and I have no idea which version it is.

[–] Mr_Dr_Oink@lemmy.world 1 points 9 months ago

Dont forget the limited length. I cant remember exactly but usb c delivering power has a max length of arpund 4 metres

[–] moon@lemmy.cafe 1 points 9 months ago

Yeah I have multiple USB cables, some at 30w, and some at 140w. Get them mixed up all the time! More companies need to at least brand the wattage on the connectors.

There's some really high bandwidth stuff that USB-C isn't rated for. You have to really press the limits, though. Something like 4k + 240Hz + HDR.

USB C is just a connector, you might be referring to Displayport over USB C which is basically just the same standard with a different connector at the end. That or Thunderbolt I guess

[–] Chriswild@lemmy.world 2 points 9 months ago

I thought thunderbolt was DP passthrough as well

[–] trafficnab@lemmy.ca 10 points 9 months ago

USB C seems like a good idea but in reality all it really did was take my 5 different, not interchangeable, but visually distinct, cables, and make them all look identical and require labeling

[–] admiralteal@kbin.social 5 points 9 months ago (1 children)

I love having mysterious cables that may or may not do things I expect them to when plugged into ports that may or may not support the features I think they do.

[–] trafficnab@lemmy.ca 3 points 9 months ago

If the implementation is so broad that I have to break out my label maker, can we even really call it a "standard"

What do Dill Pickles have to do with being work safe?

[–] lolcatnip@reddthat.com 13 points 9 months ago (1 children)

As already mentioned, DisplayPort exists. The problem is adoption. Even getting DisplayPort adopted as the de facto standard for PC monitors hasn't done anything to get it built into TVs.

[–] vox@sopuli.xyz 1 points 9 months ago (2 children)

also there's still no alternative to hdmi-cec
