Why not use the already open displayPort and make it better.

[–] glowing_hans@sopuli.xyz 69 points 6 days ago (1 children)

noo we need yet another standard!

This was exactly what I wanted to post... 😅

Displayport is an open standard in name only. The specs require membership in VESA, something that requires a hefty sum of money. Even open-source projects have to restrict code that implements Displayport because of the licensing restrictions imposed on the "open" standard.

Thought of this too, with the addition "so we can control that market".

Today I learned DidplayPort 2.1 can carry 240W.

That's a lot of power! Are there even any devices that use this?

[–] sugar_in_your_tea@sh.itjust.works 19 points 6 days ago (11 children)

PCs can use >1KW.

I don't know why you'd power a PC over DisplayPort though. New 8k monitors do go up to 190W, so we could exceed 240W if we try hard enough.

Loved automobiles with 4 wheels? Chinese cars have 13! In your face suckers!

[–] UltraBlack@lemmy.world 16 points 6 days ago (1 children)

Not really that impressive since it seems to be about four times as wide as USB-C

[–] princessnorah@lemmy.blahaj.zone 15 points 6 days ago

So is HDMI? Smaller connectors aren't always better, and it's not like it's SCART size or something.

Imagine putting out a new high bandwidth cable standard in 2025 based on copper.

The sooner display and networking move to SFP, the better.

[–] cmhe@lemmy.world 6 points 6 days ago (1 children)

SFP? You mean the every device has slots to plug in different transceiver modules? I guess that would make it more future proof, but I think that will raise the cost, and might confuse ordinary people.

You have to think about the slot-transceiver compatibility and transceiver-medium compatibility then. Hmm... but I guess that would make it more transparent what is going on than having those chips embedded inside the cables, but not sure if we can leave them out, and require the end users to take care of thinking of all these compatibilities themselves or risk fire hazards.

[–] jlh@lemmy.jlh.name 3 points 6 days ago* (last edited 6 days ago) (2 children)

yeah, I guess tvs and receivers would come with active optical cables to make it simpler, but the main thing is that optical is much cheaper and faster than copper once you get the economies of scale down on the transceivers. 1 terabit over 100km, down a cable thinner than a USB cable, is no problem with the right lasers. Meanwhile, I have interference and patent issues at 0.02tbps on hdmi cables less than a meter long.

Plenty of cheap optical HDMI cables out there, but they have compatibility issues. It would be so much easier with standard mmf mpo or SMF lc cables.

apalrd did review a unique product recently that embeds a mmf transceiver into the existing HDMI for factor, though.

Power delivery by itself could be a useful standard for ebike and power station charging (battery to battery charging too). 480w is most I've seen, but maybe USB is working on better, or 240w and more flexible/cheaper cables can work. HDMI providing 54v output would be great for most common battery system charging, and dual/triple BMSs for 2x and 3x ports/charging would be awesome.
