The following tips may help you optimize your display:

twice

.

• Adjust your computer's graphic card so that it outputs a video signal 1600 x
1200 @ 60 Hz to the LCD display. (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

. (The black border around the
edge of the screen should barely touch the illuminated “active area” of the
LCD display.)
