3. Self-diagnosis
If there is no image displayed on the monitor screen, the monitor will start a self diagnosis to
check if a signal is present.
If the notification „No Input Signal“ is displayed, i.e. there is no signal, it might be due to the
fact that the D-SUB signal is connected but the status of the monitor is on DPMS. It might
also be that the analogue signal cable is disconnected.
If the notification „Out of Range“ is displayed, this means that the frequency is out of the
normal range.
Normal range:
•
H:
30-80Khz
•
V:
56-77Hz
No Input Signal
Out of Range
