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

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.

●To clean your antistatic screen, slightly dampen a soft, clean cloth with water. If possible, use a special screen-cleaning tissue or solution suitable for the antistatic coating. Do not use benzene, thinner, ammonia, abrasive cleaners, or compressed air.
●Use a slightly-dampened, warm cloth to clean the plastics. Avoid using detergent of any kind as some detergents leave a milky film on the plastics.
●If you notice a white powder when you unpack your monitor, wipe it off with a cloth. This white powder occurs during the shipping of the monitor.
●Handle your monitor with care as darker-colored plastics may scratch and show white scuff marks more than lighter-colored monitor.
●To help maintain the best image quality on your monitor, use a dynamically changing screen saver and power off your monitor when not in use.
