■
Power Management Mode
The power management feature of this product complies with power saving requirement of
VESA DPMS. When activated, it automatically reduces unnecessary powe r consumption of
the monitor when your computer is not in use.
To use the feature, the monitor needs to be connected to a VESA DPMS compliant computer.
There is a power management step the monitor takes as described below. The power manage -
ment function, including any timer settings is configured by the operating system. Check your
operating system manual for information on how this can be configured.
If the monitor fails to operate correctly, please follow the steps below for a possible solution.
When the H-sync. signal / V-sync. signal / H and V sync. signals from the computer are off, the
monitor enters into Power Management Mode which reduces the power consumption to less
than 0.5W. The screen becomes dark. From Power Management Mode, the image reappears
in several seconds when either the keyboard or the mouse are touched again.
- Even when using the power management mode, the monitor consumes electricity. Turn off the Power
Switch whenever the monitor is not in use, during the night and weekends, to avoid unnecessary powe r
consumption.
- It is possible that the video signal from the computer may be on while the H or V sync. signal is missing. In
this instance, the POWER MANAGEMENT feature may not work properly.
