the resolution and the vertical frequency settings for the
monitor (page 11).

board’s utility. Refer to the manual of the graphics board
for details.

3. Display position is incorrect. • Adjust image position so that it is displayed properly
within the display area using the <Position> adjustment
(page 15).
• If the problem persists, use the graphics board’s utility if
available to change the display position.

actual screen image.
• Adjust the resolution using <Resolution> so that the
input signal resolution equals the resolution in the
resolution adjustment menu (page 15).
5. Vertical bars appear on the screen or a part of the image
is flickering.
• Adjust using <Clock> (page 14).

their right side.

fixed life span. When the screen becomes dark or begins
