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/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. HQView-310 and 320 have some limitations compared to HQView-300 regarding

value range, due to the use of the warp engine for scaling and auto zoom.

3.7.3. Warp

Note: Warp functionality is only available on HQView-210.

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 on top of

the following warp applications. The warp applications are Keystone, 4-Corner, Rotation, and PC (only

HQView-320). Under 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 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/Barrel distortion of the lens or screen can be adjusted again. With PC application

activated the HQView-320 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.

For convenience all settings can be reset with one button provided in the submenus.

3.7.4. Picture Format

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. E.g. 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/left side

or bottom/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. Crop preserves the

aspect ratio and scales the image to fit the screen. Dependant on the aspect ratio of the panel either the

top/bottom or right/left areas of the image are cropped. Anamorphic scales the input image such that it

is displayed with a 16:9 aspect ratio when displayed on the screen. The image is further scaled to fit into

the size of the panel. Dependant on the aspect ratio of the panel the image is then either bordered by

the right/left side or bottom/top of the panel. Non-used areas of the panel are displayed black

(letterboxed).
