The output level on VGA and Preview output can be adjusted to match exactly 700mV. This can be helpful
to balance different image brightness i.e. when using external input.
For exact adjustment, please use external measurement equipment.
Range: 85% to 100% (on-screen extra menu - see page 20)
External Input - EXTERN
A computer can be connected to the External RGB input (#23) of the Visualizer.
By tapping the EXTERN icon you can switch between the Visualizer image and the image of the external
input to be displayed to the audience.
Visualizer camera, while all other outputs (DVI, RGB etc.) can be set to output an external image.
This can be used for a "Live Picture to External Picture Comparison" on two monitors or screens with just
one Visualizer. While one monitor or screen displays an external image that can be used for comparison,
another monitor or screen can be used for presenting the image from the Visualizer.
The settings of the Visualizer can be changed in the on-screen menu (see page 20).
The Visualizer has a built-in A/D-converter in order to digitize the analog RGB signal from the computer and
output it on the RGB and DVI outputs in the selected signal format.
