I don't see anything about displays on that page. All I see is "iPhone 15 Pro lets you shoot ProRes video directly to external storage, so you can quickly switch drives and keep your iPhone camera rolling on set. Want to capture slow motion Hollywood style? Now you can record ProRes 4K at 60 fps to an external SSD."
I highly doubt the 15 Pro can drive a display. In the unlikely case that it can, you'll be limited to very low res. Why would they limit USB to 10gbps if the PHY can push the ~32gbps eDP bandwidth required for a modern display?
The "Explore Connectivity" modal window you can open in the "Gigablast
your gigabits" (meh) section, as I quoted in my original post, has this block of text:
USB‑Convenient.
Now you can connect USB‑C gear like thumb drives, fast external storage, 4K displays, and microphones. And you can charge Apple Watch or AirPods from your iPhone.9
I must have landed on the wrong side of an AB test because that text doesn't show up for me on the "Explore Connectivity" modal window. I checked with both Chrome/Windows and iOS.
Anyway I really hope that text refers to DP alt mode, not displaylink. Any USB port works with displaylink chips as long as the OS has the driver
