Video Input DVI [1] Type

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 DVI 1 Type: AutoDetect

Video ControlPanel Brightness

Set the brightness level for the touch screen.
Requires user role: ADMIN
Value space: <S: 0, 100>

Range: Select a value from 0 to 100.

Example: Video ControlPanel Brightness: 100

Video Layout Scaling

Define how the system shall adjust the aspect ratio for images or frames when there is a 

difference between the image and the frame it is to be placed in.
Requires user role: ADMIN
Value space: <On/Off>

On: Let the system automatically adjust aspect ratio.
Off: No adjustment of the aspect ratio.

Example: Video Layout Scaling: On

Video Layout ScaleToFrame

Define what to do if the aspect ratio of a video input source doesn't match the aspect ratio of the 

corresponding image frame in a composition. For example if you have a 4:3 input source (like 

XGA) to be displayed on a 16:9 output (like HD720).
Requires user role: ADMIN
Value space: <Manual/MaintainAspectRatio/StretchToFit>

Manual: If the difference in aspect ratio between the video input source and the target 

image frame is less than the ScaleToFrameThreshold configuration (in percent), the image is 

stretched to fit. If not, the system will maintain the original aspect ratio.
MaintainAspectRatio: Will maintain the aspect ratio of the input source, and fill in black in the 

rest of the frame (letter boxing or pillar boxing).
StretchToFit: Will stretch (horizontally or vertically) the input source to fit into the image frame. 

NOTE: The general limitation is that you cannot upscale in one direction and at the same time 

downscale in the other direction. In such situations the codec will apply letterboxing.

Example: Video Layout ScaleToFrame: MaintainAspectRatio

Video Layout ScaleToFrameThreshold

Only applicable if the ScaleToFrame configuration is set to manual. If the difference in 

aspect ratio between the video input source and the target image frame is less than the 

ScaleToFrameThreshold configuration (in percent), the image is stretched to fit. If not, the 

system will maintain the original aspect ratio. 
Requires user role: ADMIN
Value space: <0..100>

Range: Select a value from 0 to 100 percent.

Example: Video Layout ScaleToFrameThreshold: 5

Video Layout LocalLayoutFamily

Select which video layout family to be used locally.
Requires user role: ADMIN
Value space: <Auto/FullScreen/Equal/PresentationSmallSpeaker/
PresentationLargeSpeaker>

Auto: The default layout family, as given in the layout database provided by the system, will be 

used as the local layout. 
FullScreen: The FullScreen layout family will be used as the local layout.
Equal: The Equal layout family will be used as the local layout.
PresentationSmallSpeaker: The PresentationSmallSpeaker layout family will be used as the 

local layout.
PresentationLargeSpeaker: The PresentationLargeSpeaker layout family will be used as the 

local layout.

Example: Video Layout LocalLayoutFamily: Auto
