Monitor Specifications

The following sections give you information about the various power management modes and pin assignments for the various connectors of your monitor.

Power Management Modes

If you have VESA's DPM compliance display card or software installed in your PC, the monitor automatically reduces 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) for S2240M

Active-off mode Inactive Inactive Blank Amber Less than 0.5 W
Switch off - - - Off Less than 0.5 W

18 W (Typical) for S2240M
24 W (Maximum) for S2340M

19 W (Typical) for S2340M

The OSD will only function in the normal operation mode. When any button except power button is pressed in Active-off mode, the following messages will be
displayed:

Activate the computer and monitor to gain access to the OSD.

NOTE: Dell S2240M/S2340M monitor is ENERGY STAR®-compliance.

* 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.
