take over both outputs, working as a BOYD solution for two screens.
Typical usage is a Windows MTR solution with 2 screen outputs. They will always be
on screen, with access to all USB Devices. When a BYOD client connects to USB-C, it
will get access to 2 external screens with up to 4K30 resolution and all USB peripherals.
Please note:
Configuration and resolution available to USB-C host will depend on the computer’s specifications.
Please refer to the user manual of the computer to check if HBR2 or HBR3 is supported. With
