The following tips may help you optimize your display:
•  Adjust the computer’s graphics card to support a recommended timing mode 
(refer to “Specifications” page for recommended setting specific to your LCD 
display). To find instructions on “changing the refresh rate”, please refer to the 
graphics 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.)
