This controls the blend width and height respectively. Left and Right blend
sizes are adjusted together by the first number, and Top and Bottom blend
sizes are adjusted together by the second number.
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 logos group
Logos are like miniature Testcards, for ‘labeling’ of a video channel. Logos
are loaded into the unit via the Windows based control utility and once in the
device they can be called up for insertion as required. Horizontal and Vertical
Position plus Fade Level are all controlled using this menu group.
