Yeah, Display Port is old, but I've never seen that P and D symbol before, or at least never noticed it. And, even if it existed before Display Port over USB, you'd think that that potential confusion was a good opportunity to come up with a new logo for something that would be put next to a USB port.

It’s almost as if having all these different features would be easier to differentiate if they had different physical shapes.

I think the goal was always that you'd only ever need one type of port and one type of cable and that that port and cable could do anything. Unfortunately, because there are so many revisions and so many features are optional, you've now got a situation where the port is the right shape, the cable fits into the port, but you can't get the thing to work without reading the fine print, or without decoding obscure logos.

How about a monitor/TV for display.

I like that battery for power, though a vertical battery would be clearer.

If you're going to forbid any 2-letter initialism because it might have naughty connotations, you're not going to be left with many options.

Given that there are engineers involved I wouldn't be at all surprised if that was deliberate. Trying to get potentially offensive or otherwise NSFW acronyms past marketing without them noticing is practically an industry-wide joke at this point, which is why they are so prevalent in the FOSS space. (no marketing staff to complain)

If that's true in this case, though, hats off to whoever managed to get it though to official commercial standards
