DP is royalty free. Why are they looking for “yet another standard”

Right where my mind went

[–] bitfucker@programming.dev 11 points 5 days ago

Power delivery with higher bandwidth than USB?

[–] Jyek@sh.itjust.works 4 points 4 days ago (1 children)

DP doesn't do power delivery and DP over thunderbolt doesn't deliver enough power for a display alone.

[–] ramble81@lemm.ee 4 points 4 days ago (1 children)

That last one isn’t entirely true. I have a portable monitor that does DP-Alt over USB-C and it is powered and driven via a single cable.

[–] Jyek@sh.itjust.works 1 points 4 days ago

Small displays can be powered over thunderbolt but full features full sized displays cannot.

Now the big question is how many patents are relevant and who owns them. And even if it turns out to have cheap licensing, beating HDMI won't be easy, as DisplayPort demonstrates. Technological superiority doesn't mean shit if you can't overcome HDMI's network effect.

[–] thatKamGuy@sh.itjust.works 27 points 5 days ago

First rule of tech disruption is to ignore patents/laws and get a big enough footprint to be able to fend off the eventual litigation. Given this is China, they can mandate implementing it on mainland devices for the initial wave, and roll out later revisions into adjacent regions over time once it’s taken a foothold.

Just ask Betamax how technological superiority went against VHS.

"China"? Like, the government is making video cables now?

[–] Rin@lemm.ee -1 points 5 days ago (1 children)

Well... yeah. Every company in china is gov owned.

[–] leftytighty@slrpnk.net 12 points 4 days ago (1 children)

whereas the government in USA is company owned

[–] Rin@lemm.ee 4 points 4 days ago

Basically lmao

[–] dankm@lemmy.ca 4 points 4 days ago

I'll be all over it if it refuses to allow support for anything even remotely similar to HDCP.

[–] scheep@lemmy.world 4 points 5 days ago

that’s cool, and there’s even a USB-C version as well :D

[–] AI_toothbrush@lemmy.zip 1 points 4 days ago* (last edited 4 days ago)

That is not how standards work. Standards are standards because they are standard. Also, just use usb c, it does literally everything you need.

Edit: the article says theres a usbc compatible version, idk how thatll work but well see. Other thing, the article says hdmi doesnt have power but there are active devices that dont need power, how do those work then?

Edit2: yup i was right hdmi can cary 0.25 to 1.5w depending on version.

[–] Petter1@lemm.ee 1 points 5 days ago

Nice, I guess 😃

Why? 4k is already at the limit of what your eyes can resolve unless you have an enormous screen.

[–] Jyek@sh.itjust.works 15 points 5 days ago

People had the same argument about 4K from 2K and the same argument about frame rates higher than 60fps. But, the bigger counter to that argument is that even if that were true, additional features take up additional bandwidth and the true power of these new connector standards is in the additional bandwidth. Things like 4K HDR at very high refresh rates and additional features like 3D and VRR can have signal room on the same cable enabling the creation of displays that can do more at once than they could before. Also there are high pixel density displays and projectors that can make use of 8K and 16K footage. It's niche for now but the technology advancing is not a bad thing.

[–] monotremata@lemmy.ca 11 points 5 days ago

One use is VR, where the field of view is huge. The industry size and distance recommendations have a TV take up about 30° of your field of view, which works out to 128 pixels per degree for a 4k screen. For a headset with a 100° field of view (most are a little higher than this at this point, or at least claim to be, but it's a good baseline) you'd be looking at a 12k resolution to get the same level of clarity. But, of course, you'd need to run it at a very high framerate to avoid simulator sickness, whereas 4k often gets away with just 30 fps. Delivering power over the same cable also means just one cable.

Currently there are no GPUs to drive that high a resolution and framerate. But the cable was one limiting factor there, made especially frustrating by nVidia sticking to displayport 1.4 for so long.

[–] MangoPenguin@lemmy.blahaj.zone 2 points 4 days ago

High refresh rates and VR are 2 uses I can think of.
