Input Aspect Ratio Control
The Input Aspect Ratio control selects the aspect ratio for the
current input signal. The iScan HD
+ will automatically convert
from the selected input aspect ratio to the selected output
aspect ratio.
Pushing the
Input Aspect Ratio button once shows the current
input aspect ratio control function. You can cycle through the
available functions by pushing this button repeatedly.
For the Input AR function, pushing the
▲ or ▼ button once
shows the current setting. Pushing either of these buttons again
will cycle through the available aspect ratios. Push the
Enter/Exit button to exit the menu and go back to the Input
Aspect Ratio
selection.
For the Zoom, Pan and Borders functions, pushing the
▲ or ▼
button selects the two control settings available: horizontal and
vertical. Push the
Enter/Exit button to adjust each setting.
䊳
Push ▲ and ▼ to increase or decrease the setting.

Push Enter/Exit again to exit this mode.
Note: The 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
Input Aspect Ratio controls.
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.

Description
Input AR INAR Selects the aspect ratio of the input signal:
4/3: 4:3 aspect ratio (full-frame)
LBX: 16:9 image aspect ratio in 4:3 frame
16/9: 16:9 aspect ratio (full-frame)
PRST The Preset function is set to 16:9 input aspect ratio by default. It stores the latest custom aspect ratio settings that you
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.
Zoom ZOOM The Zoom function zooms in on or magnifies the image on your display. The minimum zoom is 100%, (no zooming) while the
maximum zoom is 150% (zoom magnification factor of 1.5X).
HOR Horizontal Zoom control. Pushing the Enter/Exit button shows the current Zoom setting.
Pushing ▲ and ▼ button increases or decreases the zooming factor.
VERT Vertical Zoom control. Pushing the Enter/Exit button shows the current Zoom setting.
Pushing ▲ and ▼ button increases or decreases the zooming factor.
Pan PAN The Pan function allows the image to be shifted up, down, left and right. Note that the Pan function can only be used after
the image has been zoomed to any value greater than 100%.
HOR Horizontal Pan control. Pushing the Enter/Exit button shows the current Pan setting. Pushing the ▲ button pans to the
right. Pushing the ▼ button pans to the left.
VERT Vertical Pan control. Pushing the Enter/Exit button shows the current Pan setting. Pushing the Enter/Exit button shows the
current Pan setting. Pushing the ▲ button pans up. Pushing the ▼ button pans the image down.
Borders BORD The Borders function 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.
HOR Horizontal Border control. Pushing the ▲ button moves the left and right borders towards the middle of the image, increasing
the border width and cutting off the sides of the input image. Pushing the ▼ button moves the left and right borders away
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.
VERT Vertical Border control. Pushing the ▲ button moves the top and bottom borders towards the middle of the image,
increasing the border height and cutting off the sides of the input image. Pushing the ▼ button moves the top and
bottom borders away from the image and decreases their height. If there are system-generated top/bottom borders already
present (e.g, when the input aspect ratio is 16:9 and the output aspect ratio is 4:3), the border height cannot be
decreased beyond the base height created by the aspect ratio conversion.
