60Hz format. If possible, use an XGA format to obtain
the best image quality for your TV/LCD monitor. If set
up under lower resolutions, a distorted picture may
appear on the screen. If set to Vertical frequency 85Hz,
some noise can be seen when PIP is on. In this case,
set the Vertical frequency to 60Hz.
If the message "OUT OF RANGE" appears on the screen,
adjust the PC output to a format listed in the chart
below.
When the PC is in the power saving mode the monitor
automatically switches to DPM (Display Power
