DP support depends on the graphic card you are using. You need consult IHV rather than us☺
Thanks

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

Yes, UEFI bios supports those usb3.0 host controllers which follow XHCI spec(http://www.intel.com/content/www/us/en/io/universal-serial-bus/extensible-host-controler-interface-usb-xhci.html), and usb3.0 device.
As for usb 3.1, it's a little complicated. What I can say is we got feedback it works at the configuration of usb3.0/3.1 devices plus XHCI 1.1 compliance controllers.
Last, for USB Type-C and DisplayPort Alternate Mode on USB Type-C, it's totally transparent for UEFI USB host controller driver and usb device driver. It should be supported by platform/silicon driver to switch the MUX.
Thanks
Feng

Hi all,
I heard that UEFI supports USB3.0. Please confirm.
Also let me know if *USB3.1 is supported in UEFI?*
Als, It would be helpful if anybody please let me know DisplayPort or USB type C is supported in UEFI.
Thanks,
With regards,
Keshava
