Controls and Installation, cont’d
devices, such as LCD (liquid crystal display), DLP (digital lamp processing) and plasma displays.
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 output
75 Ohm (input termination)
ON —
OFF — High impedance input termination
