Power consumption Screen Horizontal Vertical Power Recovery time Indicator
mode (video) sync signal sync signal consumption
1 Normal operation active yes yes < 120 W -- Green
2 Active-off (3rd mode) blank no* no* < 3 W Approx. 10 sec. Amber
3 Power-off -- -- -- 0 W (approx) -- Off
* In this mode, the signal will appear in one of three ways: The Horizontal Sync Signal alone off, the Vertical Sync Signal
alone off, or both signals off.
POWER MANAGEMENT
The power saving mode complies with the VESA Display Power Management Signaling standard. Each state of power management shall be activated
by the host computer terminating the appropriate sync signals. Blanking the video must precede termination of the sync signals. The elapsed time
counter shall also be controlled by the host computer. Reactivation of the monitor shall be accomplished from the host computer by re-establishing the
normal sync signal.
TIMING SPECIFICATION
SELF DIAGNOSIS FUNCTION
When a failure occurs, the STANDBY/TIMER lamp will fl ash a set number of times to indicate the possible cause of the problem. If there is more than
one error, the lamp will identify the fi rst of the problem areas.
