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).

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. When switching on the latency of the system is

increased by one frame. Thus, there is a difference of a PTZ setting off or on with no zoom. PTZ

settings can be saved per mode or globally, i.e. the same PTZ settings are applied when switching

input channels or changing the input mode.

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, i,e, the image can be shifted outside the active area of the display.

For convenience the PTZ settings can be reset with one button.
