Does the USB-C port on an Inspiron 27 7730 support video?
I'd like to add a 3rd monitor to my 27 7730. It appears that to do this it will need to connect to the USB-C port on the right side of the PC. Does that port support video? Before I go too far down the rabbit hole, I'd like to confirm that first but can't seem to find a clear answer.

Spec mentions only
Did not say DP Alt Mode, or DisplayPort Alternate Mode, so that is a plain USB C without support for Display port video.
DisplayPort Alternate Mode (DP Alt Mode) allows a USB-C port to transmit DisplayPort video signals directly.

Further, the online Inspiron 27 7730 All-in-One Owner's Manual page 7 does not mention monitors =
USB 3.2 Gen 2 Type-C port
Connect devices such as external storage devices and printers.
