available functions by pushing this button repeatedly.
For the Input AR function, pushing the

Note:
Th
e Zoom and Pan function are applied to the input
signal, not the output. This is an important consideration,
especially for the Pan function. For example: If a full frame
image is not zoomed more than 100%, there is nothing to pan.
However, if part of the image is not on the screen, then the
Pan function will work.
The table shows the available

The Input Aspect Ratio LED, the FPD (front panel display) and
the OSD (on-screen display) will all illuminate when the button
is pressed. The LED, FPD, and OSD will turn off automatically
after 30 seconds.

have defined. This is unique to each input. A custom aspect ratio is defined as a standard aspect ratio (16:9, LBX or 4:3)
that has been modified with the Zoom, Pan and Borders controls. If no custom aspect ratio is defined, it will remain 16:9.

ction allows you to add horizontal and/or vertical borders around the image. These borders will obscure part
of the input image. Certain input-to-output aspect ratios already result in left/right or top/bottom border being added. This
control allows the system-generated borders to be extended, or for borders to be added when none exist. As the borders are
adjusted (see below) the iScan will temporarily increase the gray level of the borders so that they are visible during the
adjustment process. The level will return to normal after the adjustment has ceased.

the border width and cutting off the sides of the input image. Pushing the

from the image and decreases their width. If there are system-generated left/right borders already present (e.g, when the
input aspect ratio is 4:3 and the output aspect ratio is 16:9), the border width cannot be decreased beyond the base width
created by the aspect ratio conversion.

decreased beyond the base height created by the aspect ratio conversion.
