Re: USB 3.1 Support in UEFI

[GN Keshava <keshava.gn@gmail.com>]

Hello Feng,

Thank you for the reply.

I understood, USB type C displayport alternate mode needs mux switch, and
hence should be supported by silicon vendor.

Whether DisplayPort is supported ? (not usb type c, i just need to use
DisplayPort (instead of vga display, i want to use displayport and
supported monitor and cable)).

Thanks again,
Keshava
