3.7.5.
Overscan
Settings: 0 to 10 in steps of 1
Overscan is used to slightly zoom into the image. Thus, the border area of an image is no longer
displayed on the screen. This cuts off unwanted features at the top or bottom from e.g. video images.
3.7.6.
Pan Tilt Zoom
This menu provided settings to zoom and shrink the image, as well as panning within the image.
Pan Tilt Zoom (PTZ) can be switched ON or OFF. PTZ mode increases the latency of the system by
one frame. PTZ settings can be saved per signal mode or globally.
The Zoom slider allows to zoom into the image or shrink it. When Aspect Lock is set to ON the separate
slider for zooming vertically is greyed out and the horizontal zoom or shrink factor is used as vertical
factor as well. The aspect ratio is preserved. When Aspect Lock is Off horizontal and vertical scaling
factors can be chosen separately.
With the Pan and Tilt sliders panning within the image in horizontal and vertical direction is possible. Off
raster panning is allowed, the image can be shifted outside the active area of the display.
For convenience the PTZ settings can be reset with one button.
