Monitor
First, set the system to VGA mode. To do this in
Windows XP or Windows 2000, depress the F8
function key during startup. Safe mode (VGA) will be
set for Windows XP or Windows 2000. Use the
operating system's video setup to change the monitor
resolution.
The monitors that come with the system are VESA
Display Data Channel and DDWG DVI compliant.
While starting Windows XP or Windows 2000, the
DDC2 monitor passes resolution and frequency
information to the system. The system interprets the
data and sets up the proper refresh rate.
If the monitor type is set to the power saving mode,
the screen remains black and the LED lights or
flashes in amber color. When the monitor is turned on
alone, or is turned on and connected to a powered-off
system unit, the monitor LED blinks in amber color.
Under the normal operating conditions, the LED lights
in green color.
