I do not really have a body for this. I was not aware that this is a thing and still feel like this is bs, but maybe there is an actual explanation for HDMI Forum’s decision that I am missing.
Display port over USB-C is totally a thing. With things like USB-PD USB seem to be getting dangerously close to becoming the standard for everything. The cables are a wreck though and are way too hard for a layperson to tell apart.
I’m a very technical person and I can’t tell them apart.
Is there a symbol?
It’s pretty simple and straightforward, all you have to so is buy the cable and a professional cable tester to see what specs it’s actually in compliance with
Don’t worry, I’m sure when USB 4 releases, they’ll retroactively change the names of USB 3.2 Gen 1 and USB 3.2 Gen 2 to “USB 4.3 Gen 0.01” and “USB 4.3 Gen 0.02” respectively. Then USB 4 will actually be named “USB 4.4 Gen 5” just because.
And none of the cables will be labeled, nor will they simultaneously support high power delivery and full data speed. We’ll need to wait for “USB 4.4 Gen 4” for that, which is when the old standard will get renamed to “USB 4.4 Gen 3.5” instead.
“USB4” (not USB 4.0) released in 2019 and “USB4 Version 2.0” (not USB 4.1) released in 2022.
These days a ~10€ gadget can tell you about the electricity going through a USB connection and what the cable is capable of. I don’t like the idea of basically requiring this to get that knowledge, but considering the limited space on the USB-C plugs I’m not sure anything is likely to improve about their labeling.
That’s good enough for me, what they called and wee where can I get one?
An example I randomly picked:
https://www.amazon.de/Messgerät-Strommessgerät-Multimeter-Strommesser-Leistungskapazität/dp/B0DK5GGVLM
I have something like this myself, it’s useful for knowing the power delivery of the cable/port combination, but I’m not sure if that really helps when it comes to determining the speed of the data transmission that the cable/port is capable of, or other features like displayport support, or which version of USB4 it might be supporting (I believe they have the same power delivery, even though the transfer speed is double).
Yeah, functionality between these varies, I know some of them can tell you what capabilities the cable’s chip spits out.
Nope! That’s part of the fun sadly. At least if you’re technical you’ll know that not all type-c cables are the same.
