Power management modes

If you have VESA’s DPM-compliant video 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 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.

VESA	Horizontal	Vertical			Video	Power Indicator	Power
Modes	Sync	Sync					Consumption
Normal	Active	Active			Active	White	46 W (maximum)**
operation							27 W (typical)
Active-off	Inactive	Inactive			Off	White	Less than 0.5 W
mode						(Glowing)
Switch off	-	-			-	Off	Less than 0.3 W
Power Consumption Pon				18.76 W

The OSD operates only in the normal operation mode. If you press any button in the active-off mode, the following message is displayed:

Dell 27 Gaming Monitor

No DP signal from your device.

Press any key on the keyboard or move the mouse or wake it up.

If there is no display, press the monitor button again to select the correct input source.
