Power Management The M1700SS Display conforms to the Video Electronics Standards Association (VESA) Display Power Management Signaling (DPMS) standard. To benefit from power management, the display must be used in conjunction with a computer and video card that implements the VESA DPMS standard. The PC automatically invokes the power management feature if you do not use the touch sensor, mouse, or keyboard for a user-defined period of time. To restore the video image, simply touch the sensor, press a key, or move the mouse.
