It is recommended to use a setting between 0 and 16 and not more than 20. For most LED videowalls
the optimum setting for Black Crush is between 8 and 20. For particularly noisy subject material 24 can
be used but detail loss may occur in dark areas. If too high a setting is chosen, image solarization may
be observed where dark image areas turn completely black or even change color.

Output Config
This Menu provides items to configure the output port.
Sync Mode
The VGA output port can be operated with separate syncs, composite syncs and Sync-On-Green.
Internally, the display interface processes data at a full ten bits per color.
Optimize for Display
Settings: DVI forced, Optimized, DVI/HDMI
Internally, the display interface processes data at a full ten bits per color. A resolution of ten bits per
color is provided for the VGA output. The color depth on the DVI-D output is determined by the
supported standard of the attached monitor or device when set to DVI/HDMI.
For DVI 1.0 and HDMI 1.1/1.2 devices it is 24 bit, for HDMI 1.3 compliant devices it is up to 36 bit.
DVI forced will output with 24 bit color depth irrespective of the supported standard of the attached
monitor.
When the Optimized setting is enabled the output resolution is automatically set to the native screen
resolution of the attached display. The color depth is determined in the same way as when set to
DVI/HDMI.
DVI Color Space and DVI Range
The color space of the DVI output port can be set to RGB or YPbPr, the range can be set to Expand,
Normal, Compress and Auto.
A limited video range is only using the following greyscale for video information - 8 Bit System: 0x01 ..
0xFE, 10 Bit System: 0x004 .. 0x03FB.
Auto makes the best choice for the range for the DVI and 3G-SDI output. If the HDMI/DVI output does
not behave as expected because the HDMI display is not evaluating AVInfoFrames properly, the range
can be changed manually.
Frame Rates
Settings: 60/50 Hz, 60/50/24 Hz, 60/50/48, 60/50/24/48
Limits the possible output frame rates that can be selected. It is primarily to be able to limit the choices
available for the Auto refresh rate configuration.
3G-SDI Data Map
720p and 1080i HD-SDI data can be output in YCbCr 4:2:2, YCbCr 4:4:4 or RGB 4:4:4 mode.
3GSDI data can be output as Level A or B data.

Output Window Size
For LED videowalls:
In this submenu the size of the output window can be scaled to fit exactly the size of your LED videowall,
i.e. the image size is reduced and positioned according to the right, left, top and bottom edge slider
setting. The image can be reduced to as few as 128x96 pixels.
A reset function is provided for convenience to set all sliders back to full output resolution.
Note: When the Windows Size function is enabled the latency of the system increases by 1 frame.
