Another great example of why proprietary connectors are stupid as hell. I’m going to be upset when my 2DS XL charger breaks and I can’t get an easy replacement.
in this case, apple display connector (adc) predates dvi, so they didn’t really have any other option for supporting an all-digital signal path to an lcd monitor, especially not one that could also power the monitor and provide usb.
this happens a lot with apple proprietary connectors. lightning predated usb-c by almost 5 years, and it was a much better connector than the existing industry standard at the time (usb micro-b). it didn’t really start to feel like a problem until many years later when usb-c started offering most of the same advantages and more.
the adc connector was mostly proprietary in the sense that nobody else used it. third party manufacturers had no problem making adapters and cables without apple’s permission, as evidenced by the the belkin dongle this article is talking about.
what you’re really asking for is an industry standard, which is different from an open standard. however, an industry standard requires the industry as a whole to buy in to it. if they say no, but you still want to solve a problem that their existing standards do not, what do you do?
industry standards also do not typically appear overnight. usually, companies put out multiple solutions trying to solve new problems, and eventually the industry coalesces around a preferred solution. USB was introduced in 1996 with full support for mice and keyboards, but it took nearly a decade to become the de facto connector for mice and keyboards.
I am asking for specifications to be released without patents or have patents signed over to an organization like VESA. Whether it becomes popular or not is another story.
i don’t think adc was encumbered by patents, at least not in any way that prevented other manufacturers from making use of it. it wasn’t locked down behind special handshakes and a certification program like lightning is. it used the same signaling protocol that dvi ended up using, which is why passive adapters like the belkin one above were possible. the additional pins on the connector were used for power and usb. the specifications were freely available, and monitors, gpus, and kvms were released that used the connector in the late '90s and early '00s.
the problem people are haivng is that this connector did not see wide use, so cables and adapters are hard to come by 25 years after the fact.
putting vesa in charge wouldn’t change anything here unless vesa decided to ditch dvi and push this connector instead. however, that probably wouldn’t have happened, because their constituents (most wintel pc makers) would have preferred the cheaper solution of not bundling video, power, and usb in a single cable.
You’re missing the point that if Apple had just given it to VESA, it would have become the de-facto standard instead of DVI because other companies would rather reuse ADC than design DVI from scratch.
i think i laid out exactly why that most likely wouldn’t have happened
i don’t think there is any reason vesa couldn’t have adopted it if they wanted, the connectors are already extremely similar. the problem is they didn’t want a connector that also handles power and usb, because that would have raised costs for pc manufacturers
It’s incredibly easy to make an adapter. You really only need the female DVI and ADC ports (you could probably sacrifice a few cables if you can’t get the connectors, too), a breadboard and some wire. https://lookanotherblog.com/diy-adc-adapter/
the adapter is passive since both connectors use the same signaling protocol
the problem is that designing tooling to manufacture a custom connector at scale is expensive, so nobody is going to do that until they know there is enough demand to at least cover the upfront cost of designing that tooling and manufacturing a bunch of these.
If the demand is low enough to not even bother stocking them anymore, it would seem like someone could offer to sell them on Etsy or something, doesn’t seem to require much much tooling.
Really? If you just look up “3DS USB charging cable” on a popular jungle themed online retailer it comes up with loads of them. Sure you can find the same on AliExpress or eBay.
And yes yours uses the same cables/charger as the 3DS.
Thankfully, at least recently, most devices have settled on only a few standards. And some older devices can be modded to work with newer ports. I know rhere are some mods to add a usb-c port to the 2ds, and from what I understand they’re not too difficult to do.
The newest law covers pretty much everything one could think of being powered by usb, and more, especially now that with usb-c it can deliver higher voltages and currents, not just 5V/2A.

As a consumer, would have been pretty cool if DVI carried USB too.
Instead, almost every monitor bundles a USB hub that needs an extra cable. Not sure how that saved manufacturers money.
ADC is incredibly inconvientient, because it doesn’t support hotplugging. It also requires the computer to contain a power supply for the screen.
If it were, they’d likely be expired by now.
I wonder if an adapter could be made some “DIY” way, if it needs to be active, it could be a fun project for someone into FPGAs.

I didn’t notice at first, the article itself links to a seemingly easy way of making a DIY adapter:

They did, it’s called USB-C. Apple was heavily involved in the development of USC-C.
Luckily they are popular enough that you can get pretty inexpensive cables that allow USB charging.
Where? I haven’t been able to find it

Also thanks to the EU forcing the manufacturers (of smartphones at least) to go for the same standard

Yes. I have and will be doing type C conversions a lot.
Aren’t those cables available in quantities though?
They are for now
