Video controls
1 Input 1 through 4 buttons — The Input 1 through Input 4 buttons select the
associated video input to scale (except for input 4 when configured as
passive) and display on the output(s). Audio follows (switches with) the front
panel video selection.
Input 1 through 4 LEDs — The lit Input 1 through Input 4 LED indicates the
video and audio input that is selected.
2 Blank button — The Blank button switches the output(s) to a black screen.
Blank turns off the R, G, and B video output signals only; the H and V sync
outputs remain active. This ensures that the display(s) retains sync lock.
Blank has no affect on input 4 when it is passive (unscaled).
Blank LED — The Blank LED indicates that the video output is blanked.
3 Freeze button — The Freeze button locks the output display to the current
image being input. When the freeze function is enabled, the Freeze LED is lit.
To unfreeze the image, press the Freeze button again.
When the output is frozen, the video input cannot be removed without losing
the displayed image.
