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.
Video Input DVI 1 Type: AutoDetect
Example:
Video ControlPanel Brightness
Set the brightness level for the Touch controller.
Requires user role: ADMIN
Value space: <0..100>
Range: Select a value from 0 to 100.
Video ControlPanel Brightness: 100
Example:
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: <Off/On>
Off: No adjustment of the aspect ratio.
On: Let the system automatically adjust aspect ratio.
Video Layout Scaling: On

Introduction Web interface System settings System settings
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 Video Layout ScaleToFrameThreshold setting (in percent), the image is
stretched to fit. If not, the system will maintain the original aspect ratio.
MaintainAspectRatio: Maintain the aspect ratio of the input source, and fill in black in the rest
of the frame (letter boxing or pillar boxing).
StretchToFit: 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.
Video Layout ScaleToFrame: MaintainAspectRatio
Example:
Video Layout ScaleToFrameThreshold
Only applicable if the Video Layout ScaleToFrame setting 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 setting (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.
Video Layout ScaleToFrameThreshold: 5
Example:
Video Selfview
Determine if the main video source (self view) shall be displayed on screen.
This setting is obsoleted by the Video SelfviewDefault Mode setting as from TC6.0.
Requires user role: USER
Value space: <Off/On>
Off: Do not display self view on screen.
On: Display self view on screen.
Video Selfview: On
