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.
Aspect Ratio
Settings: Scale, Preserve
The system can be set to scale the input image to a fixed output resolution or, with the setting preserve,
to choose an output resolution matching the input resolution.
3.7.3.
Warp
Submenu for warping the image. The warp applications are Keystone, 4-Corner and Rotation. 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 it fills a 16:9 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 the 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.
Standard preserves the aspect ratio of the incoming image and scales the image to fit into the size 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. Either the top and bottom or right
and left areas of the image are cropped.
Anamorphic scales the input image so that it is displayed with a 16:9 aspect ratio. The image is further
scaled to fit into the size of the panel 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).
