monitor.

Check if the computer system is 
switched on and in power saving/
standby mode.

Unstable picture

Check if the specification of graphics 
adapter and monitor is in compliance 
which may be causing the input signal 
frequency mismatch.

off-center, too

the OSD, adjust focus, clock, H-

Check the display setting on your 
system. In case of a missing image, 
please select another resolution or 
vertical refresh rate.

Wait for a few seconds after adjusting 
the size of the image before changing

switching off the monitor.
