J40: Vertical sync width jumper — This jumper adjusts the
vertical sync pulse width. Some digital display devices
have very specific requirements for incoming sync pulse
width. If no picture displays, the picture cuts in and out,
or the picture is scrambled, try adjusting the vertical sync
pulse width or switching from ADSP™ to DDSP™.
• If the jumper is placed on pins 1 and 2, the output vertical
sync pulse is short (narrow).
• If the jumper is placed on pins 2 and 3, the output vertical
sync pulse is wide. This is the default setting.
5. Replace and fasten the enclosure cover, reversing step 2.
