Power Management Modes - Dell S3221QS User Manual

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 Standby Mode*. If the computer detects input from the 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.
* Zero power consumption in Off Mode can only be achieved by disconnecting the
power cable from the monitor.
