Auto-Sleep mode
-
The display supports an OSD option called Auto-Sleep mode that allows you to enable or disable a reduced power state for the display. When Auto-Sleep mode is enabled (enabled by default), the display will enter a reduced power state when the host PC signals Low Power mode (absence of either horizontal or vertical sync signal).
-
Upon entering this Reduced Power State Sleep mode, the display screen is blanked, the backlight is turned off and the power LED indicator turns amber. The display draws less than 0.5W of power when in this Reduced Power mode. The display will wake from the Sleep mode when the host PC sends an active signal to the display (for example, if you activate the mouse or keyboard).
