This controls the gamma for the blend width and height respectively. Left and Right
blend gamma values are adjusted together by the first number, and Top and Bottom
blend gamma values are adjusted together by the second number.
The gamma values affect the linearity of the blended edges, allowing for the fact that
projectors do not normally output a picture whose brightness is directly proportional
to the voltage within the video signal. These values are best adjusted once any
overlapping images are aligned with each other
This controls a ‘compensation’ value that sets the minimum brightness of the centre
and side areas during edge-blending. It is used to compensate for the fact that
projectors cannot generally output a purely black signal – and hence the overlap
area would normally be brighter as a result. Increasing the centre area’s value will
compensate for this.
For 2x2 (or higher) setups, the side value can also be adjusted to correct for corner
brightness errors

Items Associated with the Adjust sources group
The ‘Adjust Sources’ menu group accesses the parameters associated with the
processing amplifiers used for each input (RGB, CV, YC, etc.). They allow you to
fine-tune an incoming signal to optimize its color, brightness or even sharpness.
Not all settings are available for all input types, and not all input types listed here
may be available on your unit.
It is recommended that you Store your settings once you’re happy with them in
readiness for future use.
This menu item selects the input connection for which you want to make adjustments
to. As in the image above, changes will only be made to the source connected to
RGB1. Once the selection has been made, all changes made using the following
operating parameters will only apply to the selected input.
Selection of a CV/YC source will reveal different menu items that
allow adjustments beyond those used for RGB sources. The
menu discussions that follow relate first to RGB sources, then to
CV / YC type sources.
