dual 4K@30fps on USB 5Gbps. How is that possible?

Hello Kris,

I'm afraid we wouldn't explain how in details.
But that dock is dual 4Kp60 + single 4Kp30 over alternate mode. Thunderbolt not required or useful here. The third display does not use USB traffic so can't be added in the same bandwidth budget.
Dock does drive the displays directly, so the bandwidth calculation doesn't really work that way. It does on the monitor link, but not on the USB link.

Kind regards,
Alban
