The settings adjustable with the user controls are viewed through the On-
Screen Display (OSD). Press any of the OSD buttons to activate the OSD.
The LCD monitor needs
time to become thermally
stable the first time you turn it on
each day. Thus, to achieve more
accurate adjustments for
parameters, allow the LCD
monitor to warm up (be On) for
at least 15 minutes before
making any screen adjustments.
