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/Vertical Position
Settings: in steps of 1 pixel/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. If Pan Tilt Zoom is activated Edge Control is disabled. It does effectively the same, but
has greater range.
3.7.3.
Warp
Note: Warp is only available for HQView-510, 520 and 530. PC Warp is only available on HQView520
and 530
Details of the submenu for warping the image and defining projection condition.
The projection condition can be Front Tabletop, Front Ceiling, Rear Tabletop 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/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. Please note that this function is designed to be used on Flat rectangular screens
only. For more complex shapes please 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/Barrel distortion of the lens or screen can be adjusted again.
Special Portrait 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 HQView-520 and 530 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.
