User manual
3.7. Geometry
This menu contains adjustments associated with setting up position, aspect ratio and scale of the input
signal. Scale can be as simple as an overscan up to arbitrarily warping the image.
3.7.1. Horizontal and Vertical Position
Settings: in steps of 1 pixel and line
Change the positional values to match the display boarders.
3.7.2. Edge Control
Submenu for changing the position of the image edges, effectively scaling the image in horizontal and
vertical direction.
3.7.3. Warp
Submenu for warping the image and defining projection condition. The projection condition can be Front
Table top, Front Ceiling, Rear Table top or Rear Ceiling. The corresponding image flip is applied on top
of the following warp applications.
The warp applications are Keystone, 4-Corner, Rotation, and PC. Special portrait warp applications for
clockwise (90°) and counter-clockwise (270°) rotation with scaling are provided as well.
Under the Keystone application the image can be adjusted to match a horizontally and vertically tilted
screen. Also, Pin and Barrel distortion of the lens or screen can be adjusted simultaneously.
Under the 4-Corner application all corners can be moved and the image is calculated to fit into the given
trapezoid.
The Rotation application let you rotate the image from -180 to 180 degree (one full circle). At the same
time Pin and Barrel distortion of the lens or screen can be adjusted again.
Predefined warp maps for portrait mode applications are provided. A 9:16 input image area is rotated
and scaled such that is fills a 16:9 screen.
With PC application activated the VP-792 communicates with the PC tool Warp Generator. Warp
Generator allows you to define an arbitrary screen in live operation by projecting a grid on the surface
and move the grid points to get a rectangular output. This grid information can then be downloaded in
one of eight slots used for real-time processing of image data which make the image appear rectangular
on a curved screen
The warp generator software allows rotation, scaling and warping simultaneously..
For convenience all settings can be reset with one button provided in the submenus.
3.7.4. Picture Format
Available Settings: Standard, Full Screen, Crop, Anamorphic
Picture Format allows a user to select the displayed aspect ratio where the signal input is at variance
with the display panel’s natural aspect ratio.
Note that some aspect ratios may not be applicable to all signal types, in which case selecting a non-
applicable aspect ratio conversion will have no effect on the displayed image. when a 16:9 image is
displayed on a 16:9 panel all settings give an identical full screen image.
Standard preserves the aspect ratio of the incoming image and scales the image to fit into the size of
the panel. Dependant on the aspect ratio of the panel the image is either bordered by the right and left
side or bottom and top of the panel. Non-used areas of the panel are displayed black (letterboxed).
Full Screen scales the image to the size of the panel without preservation of the aspect ratio.
