Solution
Your computer is configured for
an invalid monitor via the Setup
Program; the CRT Type item must
be set to match the PS/2 display
or equivalent fixed frequency
monitor.
You must have a multifrequency ex-
tended graphics monitor to use the
extended 800 600 graphics mode
of the computer. If you are using a
multifrequency monitor, try adjust-
ing the vertical hold and vertical po-
sition adjustments.
This high-resolution mode is inter-
laced and requires the use of an
8514 or equivalent interlaced
IBM
monitor.
Some multifrequency monitors do
not automatically adjust vertical
screen size as
IBM PS
do. Adjust your display for best re-
sults.
