Overscan is used to slightly zoom into the image. Therefore, 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. head switching
in legacy video images.
Settings: 0 to 10 in steps of 1
Default: 0
6.1.4.3 Pan Tilt Zoom (PTZ)
This menu provides settings to zoom and shrink the image, pan horizontally and tilt vertically within the
image. PTZ can be switched on or off and the settings can be saved per input channel or globally, i.e. if
applied globally the same PTZ settings are applied when switching input channels or changing the input
mode. The Zoom setting allows zooming into the image or shrink it.
When Aspect Lock is set to On, vertical zoom is disabled and the horizontal zoom or shrink factor is also
used to vertically adjust the image. In this mode, the aspect ratio is preserved. When Aspect Lock is Off,
horizontal and vertical scaling factors are set separately, regardless of the input image aspect ratio.
Off raster panning is also allowed, i,e, the image can be shifted outside the active area of the display.
The PTZ settings can be set to the default settings with the reset button.
