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.
SELF DIAGNOSIS FUNCTION
If a failure occurs, the power LED indicator will flash a set number of times to indicate the possible cause of the problem.
Model Information: Press and hold the menu button for more than 5 seconds while inputing a signal.
