Power Saving Function
This display meets the power saving guidelines set by the International
E
NERGY 
S
TAR Program. It is capable of reduced power consumption when
used with a computer equipped with Display Power Management Signaling
(DPMS). By sensing the absence of the sync signal coming from the computer,
it will reduce the power consumption as follows:
 
 CAUTION
The Power Saving function will automatically put the display into Active-off state if the
power switch is turned on without any video signal input. Once the horizontal and
vertical syncs are sensed, the display will automatically return to its Normal operation
state.
 Note
1) To lower the power consumption to 0 W, disconnect the power cord.
