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.

1. Analog Input

or Any Key on Keyboard or Move Mouse

2. Digital Input

Plug and Play Capability

You can install the monitor in any Plug and Play-compatible system. The monitor automatically provides the computer system with its Extended Display Identification Data (EDID) using Display Data Channel (DDC) protocols so that the system can configure itself and optimize the

monitor settings. If desired, you can select different settings, but in most cases monitor installation is automatic.
