Power saver

Power control system, also called (Power Saver), is installed inside the LCD monitor.
If the monitor has not been used for a certain period of time, the system will turn the monitor to low voltage mode to save power. Slight movement of the mouse or any pressing key on the keyboard will return the original image.
The VGA card inside the computer configures Power Saver. You can use your PC to set the function.
The LCD monitor is compatible with EPA ENERGY STAR and NUTEK if used with a VESA DPMS computer.
To save power, turn off the LCD monitor power when not in use.

Plug & play

The new VESA Plug and Play function is used, eliminating the complicated and time-consuming installation process.
Use the Plug and Play system without encountering the usual installation problems. Your computer system can easily identify and automatically adjust the 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 auto adjust your monitor.
