Plug in Pro Display XDR
Pro Display XDR automatically turns on when you plug it into power and connect your Mac using the included Thunderbolt 3 Pro Cable.
Route the cables through the opening in Pro Stand, ensuring that the Thunderbolt 3 Pro Cable is plugged into the Thunderbolt 3 port on Pro Display XDR.
Tip: If the display doesn’t turn on the first time, try unplugging it from the computer and plugging it back in. If that doesn’t work, unplug the Pro Display XDR from its power source and then plug it in again.
