Geometry
This menu contains adjustments associated with setting up position, aspect ratio and scale of the input
signal..
3.10.1.
Horizontal and Vertical Position
Settings: in steps of 1 pixel or line
Change the positional values to match the display boarders.
3.10.2.
Edge Control
Submenu for changing the position of the image edges, effectively scaling the image in horizontal and
vertical direction.
3.10.3.
Warp
Note:- This menu is only available when Display Type is chosen as
Projector
.
The warp applications are Keystone, 4-Corner, Rotation, Protrait 90°, Portrait 270° and PC.
The projection condition can be Front Table-top, Front Ceiling, Rear Table-top or Rear Ceiling. The
corresponding image flip is applied in addition to the following warp applications.
The warp applications are
Keystone, 4-Corner, Rotation, Portrait and PC
.
In 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 linearity is calculated to fit into
the given trapezoid. Note that this function is designed to be used on Flat rectangular screens only. For
more complex shapes use the PC mode.
The
Rotation
application rotates the image from -180 to 180 degree (one full circle) one degree at a
time.. At the same time Pin and Barrel distortion of the lens or screen can be adjusted again.
Special
Portrai
t warp applications for clockwise (90°) and counter-clockwise (270°) rotation with scaling
are provided. These functions cut out the centre of a normal landscape video signal, rotate it by 90
degrees and then scales that centre portion of the signal to fit a portrait mounted screen. Predefined
warp maps for portrait mode act on a 16:9 input image. The area is rotated and scaled such that is fills a
9:16 screen.
With
PC
application activated the VP-794 communicate 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.
For convenience all settings can be reset with one button provided in the submenus.
