Power Saver
A power control system, Power Saver, is installed inside the LCD monitor. If the LCD
monitor has not been used for a certain period of time, the system will turn the LCD
monitor to low voltage mode to save electrical power. Slight movement of the mouse or
pressing any key on the keyboard will return the original screen image. You can use your
PC to set the function.
The LCD monitor is compatible with EPA ENERGY STAR and NÜTEK if used with a
VESA DPMS computer. To save power, turn off the LCD monitor power when not in use.
Plug & Play
VESA Plug and Play eliminates the complicated and time-consuming installation
process. Your computer system will identify and automatically adjust the LCD monitor. The
LCD monitor uses Display Data Channel (DDC) to send Extended Display
Identification Data (EDID) to the computer system, so the computer system can
automatically adjust the LCD monitor.
