Solution
Install the display drivers on
the diskette included in the
upgrade kit.
Press any key or type in your
password.
1. Be sure the monitor
cable is securely
connected to the
workstation.
2. In a 2-monitor system or
if another monitor is in
close proximity, move
them apart to be sure
they are not interfering
with each other's
electromagnetic field.
Leave at least 3 inches (7.6
cm) of ventilation space. Be
sure there is nothing sitting on
top of the monitor obstructing
the air flow.
