On the downside, you canβt tell what the port supports by just looking at it.
Even with this graphic, I still don't know what they support. Is circle-20 also 20gbps? What is the speed when there's no number? Do the non-DP ones not support displays at all? And there appears to be no such thing as USB4-DP?
And good luck getting your grandmother to identify any of this over the phone. "Is it marked SS-subway diagram-20, or circle-20-subwaydiagram? Yes it's etched gray on slightly different gray, go put on your strongest glasses first, grandma."
Also, who's at reading distance from a USB port half the time? Sometimes they're on the front of a device, but they're just as often hidden behind something or in a hard-to-reach place. Monitors and PCs come to mind.
It's not like they're going to change when you're not looking.
USB4 supports DP and TB3.
My phone doesn't have any kind of marking anywhere on it so I'm guessing it's USB DP
Googling for it, my phone (pixel 9 pro fold) has USB 3.2, so it shouldn't be able to drive a DP display
Was wondering about thunderbolt. Found this, which I interpret as
usb 4 40 = thunderbolt 4
Wow what a marketing ~~scum~~ trick to show all compatible older generations as separate products
