Setting RGB delay
The switcher can briefl y blank the RGB (video) output while it switches to the
new input’s sync source, and then switches the RGB signals. This allows a brief
delay for the display to adjust to the selected input’s sync timing before displaying
the new picture, which then appears without glitches. RGB delay, also known as
Triple-Action Switching or video mute switching, is user selectable from 0 to 5
seconds, in half-second increments.
You can set the RGB delay interval on the front panel or by using RS-232/RS-422
and Ethernet ports with either the SIS, Windows control program, or HTML pages.
