Rather than messing around with logos why not mandate a specific typeface to be used mentioning the version/speed/capacity immediately next to the logo? Rather than screwing around with more hieroglyphics pretending it is the solution, just write it out.

I'm confused. Isn't that basically what they are doing here?

Earlier quoted context omitted.

I don't know much about altmodes. What does the cable need to do to make displayport work right?

It needs the USB3 diff pairs. It is perfectly possible to have a USB2-only cable with USB-C plugs. You never know with fly by night brands where they've skimped on production costs.

I see. I think that anything with these certifications / logos would be USB3 (or 4).

Please, for the love of god, make it obvious if a USB C cable can be used as a display cable or not. One thing that absolutely blows about USB C is that they all look the same, but to connect my LG UltraFine to my GTX 2070 I had to do literally hours of research before I could find a reliable cable on Amazon that was a “bidirectional USB C DisplayPort” cable because I naively assumed that USB C was a general purpose…

What cable did you end up going with, and did it work? Am in an almost identical situation and would like to avoid "hours of research" myself!

It seems to dilute the oneness, and hence the perceived value of USB-C, not to mention the logos are fugly.

It's the other way around. USB-C tries to be too many things at once and this leads to confusion. They should have either mandated that it only handles the top end of the spec at the physical level and gracefully degrades if that isn't available on either end (so at least the cable would be standard), or use physically different plugs to avoid accidental frying of equipment and things just plain not working.

If the plug fits -> it should work.

In classic USB committee style, they try to do the right thing and still bungle the naming/marketing. Just like the absurd “hi-speed/super speed” debacle, they fail to mention what people really want to know: “Will this drive my monitor?” — bandwidth tells me most of what I need to know but to the average user it makes no sense. “Is this a fast cable for my external drive”? “Is this really expensive cable overkill fo…

With bandwidth, the monitor packaging/manual can at least simply say that you need a port and cable that both say at least 10 on it.

That's much better than the previous mess at least.

The alternative would be one new logo and a requirement that all the cables have to meet all the criteria, which would in theory "only" make cables more expensive, and in practice lead to many fake/mislabeled cables that work sometimes.

Isn't charging also complicated by some fast-charge protocols? I know the phone accessory companies are always saying things like "Supports Qualcomm Quick Charge 23.45 with Sprinkles" in addition to "18 watts". I think the cables might more or less be the same, but it's still a complex ecosystem question.

I have two devices with USB-C chargers. I can make a reasonable guess that the bullion-cube sized charger provided with the phone isn't gonna be able to supply a thirsty 15" laptop, but will the 65-watt laptop brick be capable of the right wiggle-dance to convince the phone to quick charge, or will I plug it in overnight and find it saying "62% - charging slowly" when I check in the morning? I end up carrying both when I travel, eliminating the convenience that USB-C promised.

I'm also going to go out there and say that USB-C laptop charging is stupid when most devices are limited on their USB-C ports. On my laptop, I can apparently use a USB-C to DisplayPort cable to get 4k/60 output (while the HDMI is limited to 4k/30). But now I've got no way to charge it.

I wonder if PoE could be delivered through a docking station as an alternative means of charging a laptop.

On my old-ish XPS I've mitigated this limitation with this 18 Euro cable that unifies display-port and USB-C power delivery:

Works like a charm.

>I'm also going to go out there and say that USB-C laptop charging is stupid when most devices are limited on their USB-C ports.

USB-C charging isn't stupid, it's actually super convenient; what's stupid is laptop manufacturers who cheap out on ports and display outputs to save $10. The 4K@30Hz HDMI 1.4 ports are a killer when I still see them in 2021. But hey, manufacturers do this crap since the technology clueless bean-counters in megacorps fall for the cheap laptops with crippled ports scam if they see a saving of $10 per machine on the 10K unit fleet. For the same reason they still sold you 720p TN displays on some laptops until recently. And I think some still do in developing countries if you ask for them. Crazy, I know.

If it explicitly said the USB version I'd agree, but what they're doing here is more of the same pointless nonsense. This[0][1] is the junk that consumers currently need to wade through, now we have several more additions to it.

I don’t know what laptop you have. DisplayPort is native to USB C cabling and the Type C connector is the modern DisplayPort connector.

I have my Mac plugged into a Thunderbolt display that uses DisplayPort to display the image and also powers the computer. This has been the original vision going back the the lightpeak days.
