Refresh Rate selection box
NOTE: The front panel Output Rate button can be used to select the resolution, but
every front panel rate selection defaults to 60 Hz. Different refresh rates can be
selected only by using this screen or RS-232 control.
The Refresh Rate selection box identifies the currently selected output refresh rate and allows
you to select a different rate.
To select a different rate, use the front panel or IR remote control or button to highlight
the desired resolution and press the Enter button.
Sync Polarity selection box
The Sync Polarity selection box identifies the currently selected sync polarity and provides
the ability to select different sync polarities. The display or projector may require video with
positive or negative horizontal (H) and/or vertical (V) sync polarity; consult the diplay or
projector manual.
To select a different sync polarity, use the front panel or IR remote control or button to
highlight the desired sync format and press the Enter button. The default setting is H–/V–.
Signal Type selection box
The Signal Type selection box identifies the currently selected output signal format (RGBHV,
RGBS, RGsB, or progressive component video [Y, B-Y, R-Y]) and provides the ability to select
a different type. To select a different sync type, use the front panel or IR remote control or
button to highlight the desired sync type and press the enter button. The default setting is
RGBHV.
NOTE: Another way to select the output signal type is to press and hold the PIP On
button while you apply power to the switcher. This action toggles the signal type
between RGBHV and progressive component video. If RGB was selected the last
time the switcher was powered, the signal type switches to component video. If
component video was selected, the signal type switches to RGB.
