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.
Note: HQView-2xx V2 excels original HQView-2xx hardware. PTZ is only available on HQView-2xx V2
hardware (check the serial number batch for HQView-2xx or HQView-2xx V2 marking, the product
name as indicated by the top label is HQView-2xx with no further extensions in either case). Firmware
for HQView-2xx V2 also operates on HQView-2xx hardware, only the PTZ menu is greyed out.
