Dell Power Button Sync (DPBS) • The C2422HE/C2722DE/C3422WE monitor is designed with Dell power button sync (DPBS) feature to allow you to control PC system power state from the monitor power button. This feature is compatible with Dell OptiPlex 7090/3090 Ultra platform, and is only supported over USB-C interface.
Go to System Settings In the drop-down menu of When I press the power button, there are a few options for selection namely Do nothing/Sleep/Hibernate/Shut down, and you can select Sleep/Hibernate/Shut down. NOTE: Do not select Do nothing, otherwise monitor power button cannot sync with PC system power state.
Connecting the monitor for DPBS for the first time USB Type-C Initial monitor power state(OFF) Initial system power state(OFF) USB Type-C For the first time setting up the DPBS function, please follow below steps: 1. Make sure both the PC and monitor is OFF. 2. Connect the USB Type-C cable from the PC to the monitor. 3. Press the monitor power button to turn ON the monitor. 4. Both the monitor and PC will turn ON momentarily.
Using DPBS function When you press the monitor power button or PC power button, the Monitor / PC state is as follows: 1 USB Type-C 2 Initial monitor power state(ON) New power state of monitor(OFF) Press PC/Monitor power button New power state of system(OFF) Initial system power state(ON) USB Type-C 1 USB Type-C USB Type-C 2 Initial monitor power state(OFF) New power state of monitor(ON) Press PC/Monitor power button Initial system power state(OFF) USB Type-C New power state of system(ON) U
Slide to shut down your PC When the monitor and PC power state are both ON, while you press and hold 10 seconds on monitor power button, the PC will shut down.
Connecting the monitor for USB-C Multi-Stream Transport (MST) function (C2422HE/C2722DE only) A PC is connected to two monitors in an initially OFF power state, and the PC system power state is in sync with Monitor 1 power button. When you press the Monitor 1 or PC power button, both the Monitor 1 and PC turns ON. Meanwhile the Monitor 2 will remain OFF. You need to manually press the power button on Monitor 2 to turn it ON.
