OFF — If this switch is set to Off, the interface
performs sync processing operations,
such as horizontal shift, using Extron’s
ADSP™.
Turning on the DDSP feature disables the
horizontal shift control.
SERR (serration pulse)
Many display devices, such as LCD and DLP
projectors and plasma displays, must not have
serration pulses present in the sync signal in
order to display images properly. Flagging or
bending at the top of the video image is a sign
that the serration pulses should not be present.
ON — When this switch is set to On, serration
pulses are present with sync signal
output
OFF — When this switch is set to Off, serration
pulses are not present with sync signal
