Setting Up the Monitor
Connecting the Monitor for USB-C
The Dell Optiplex 7090 Ultra platform has two USB-C ports, so both Monitor 1 and
Monitor 2 power state can sync with the PC.
When the PC and two monitors are in an initially ON power state, pressing the
power button on Monitor 1 or Monitor 2 will turn OFF the PC, Monitor 1, and
Monitor 2.
NOTE: DPBS only supports the port with icon.
