DVI Range
When set to Default CEA, the output modes have limited range, and VESA modes have full range.
Therefore, an incoming limited range mode is either passed through when the output is set to a CEA
output mode or expanded when the output is set to a VESA mode. An incoming full range mode is
either compressed when the output is set to a CEA output mode or passed through when the output is
set to a VESA mode.
If the HDMI/DVI output does not operate properly, the range can be changed manually. A limited
video range is only using the following greyscale for video information - 8 Bit System: 0x10 .. 0xEF, 10
Bit System: 0x040 .. 0x03BF, 12 Bit System: 0x100 .. 0xEFF.
Settings:
Default, Limited, and Full
Default:
Full

Video Wall
The Video Wall menu provides controls to set up multiple units in a multi-screen application.
Multiple screens are stitched together to provide a bigger display with higher resolution than a single
display. Each display is driven by a separate unit.
In a multi projection display the individual projections typically are chosen to overlap to give seamless
transitions. Multiple LED walls or LCD/Plasma screens do not have overlapping regions. The Blend
Width is set to zero. When using Video Wall to drive one single large screen, it is essential that all
units are I/O locked or genlocked, otherwise motion tear will be observed at the boundaries of the
image processed by each unit.
6.2.4.1
Auto Zoom
Switches on the auto zoom resizing the video image to display the assigned part of the total image.
When Auto zoom is turned on, the processor will cut and scale the portion of the picture as defined by
the matrix size and position settings that are described next. Autozoom should be turned off when the
unit is connected to a multi-head graphics card where the content has been split.
Settings
