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 input from keyboard, mouse, or other input devices is detected by the
computer, the monitor automatically 'wakes up'. 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 Green 45 W (typical)
Active-off mode Inactive Inactive Blanked Amber Less than 2 W
Switch off - - - Off Less than 1 W
NOTE: The OSD only functions in the 'normal operation' mode. One of the following messages appears when the “menu” or “plus” buttons are pressed
when in Active-off mode.
