The following tips may help you optimize your display:
• Adjust your computer's graphic card so that it outputs a video signal 1280 x
1024 @ 60 Hz to the LCD dislay. (Look for instructions on "changing the
refresh rate" in your graphic card's user guide.)
• If necessary, make small adjustments using H. POSITION and V. POSITION
until the screen image is completely visible
edge of the screen should barely touch the illuminated "active area" of the
LCD dislay.)
