Power Management Modes
If you have VESA's DPM™ compliance display card or software installed in your PC, the monitor can automatically reduce its power consumption when not in use.
This is referred to as Power Save Mode*. If the computer detects input from keyboard, mouse, or other input devices, the monitor automatically resumes
functioning. The following table shows the power consumption and signaling of this automatic power saving feature:
VESA Modes Horizontal Sync Vertical Sync Video Power Indicator Power Consumption
Normal operation Active Active Active White 23 W (maximum)
Normal operation Active Active Active White 17 W (typical)

The OSD will only function in the normal operation mode.
Activate the computer and the monitor to gain access to the OSD.
* Zero power consumption in OFF mode can only be achieved by disconnecting the main cable from the monitor.
** Maximum power consumption with max luminance and Contrast, Dell Soundbar, and USB active.
