Video Input Connector [1..4] RGBQuantizationRange
The devices connected to the video input should follow the rules for RGB video quantization
range defined in CEA-861. Unfortunately some devices do not follow the standard and this
configuration may be used to override the settings to get a perfect image with any source. The
default value is set to Full because most sources expects full quantization range.
Requires user role: ADMIN
Value space: <Auto/Full/Limited>
Auto: RGB quantization range is automatically selected based on video format according to
CEA-861-E. CE video formats will use limited quantization range levels. IT video formats will
use full quantization range levels.
Full: Full quantization range. The R, G, B quantization range includes all code values (0 -
255). This is defined in CEA-861-E.
Limited: Limited Quantization Range. R, G, B quantization range that excludes some code
values at the extremes (16 - 235). This is defined in CEA-861-E.
Example:
Video Input Connector 1 RGBQuantizationRange: Auto
Video Input Connector [4] DviType
The official DVI standard supports both digital and analog signals. In most cases the default
AutoDetect setting can detect whether the signal is analog RGB or digital. However, in some
rare cases when DVI-I cables are used (these cables can carry both the analog and digital
signals) the auto detection fails. This setting makes it possible to override the AutoDetect and
select the correct DVI video input.
Requires user role: ADMIN
Value space: <AutoDetect/Digital/AnalogRGB/AnalogYPbPr>
AutoDetect: Set to AutoDetect to automatically detect if the signal is analog RGB or digital.
Digital: Set to Digital to force the DVI video input to Digital when using DVI-I cables with both
analog and digital pins and AutoDetect fails.
AnalogRGB: Set to AnalogRGB to force the DVI video input to AnalogRGB when using DVI-I
cables with both analog and digital pins and AutoDetect fails.
AnalogYPbPr: Set to AnalogYPbPr to force the DVI video input to AnalogYPbPr, as the
component (YPbPr) signal cannot be auto detected.
Example:
Video Input Connector 4 DviType: AutoDetect

Video Input Connector [5] SignalType
Connector 5 can be used for either S-Video or Composite video input format. Use this setting
to configure which video format the BNC connector(s) are used for.
Requires user role: ADMIN
Value space: <Composite/YC>
Composite: Connector 5 is configured for composite video input. Only the BNC connector
that is labeled "Y" is used.
YC: Connector 5 is configured for S-Video input. Both BNC connectors ("Y" and "C") are
used.
Example:
Video Input Connector 5 SignalType: Composite
Video Layout DisableDisconnectedLocalOutputs
This setting is fixed to On.
Requires user role: ADMIN
Value space: <On>
On: The built-in layout engine does only set layout on local outputs having a monitor
connected.
Example:
Video Layout DisableDisconnectedLocalOutputs: On
