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.
Then they could have released an open standard instead of creating a proprietary connector.
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.
ADC is incredibly inconvientient, because it doesn’t support hotplugging. It also requires the computer to contain a power supply for the screen.
