3.5.7. Output Gamma
Settings: 1.0 to 3.0 in steps of 0.1
Output gamma allows to re-gamma video signals with pre-configured gamma values to match the
display. Input gamma and output gamma both default to 2.2. If they are both set to the same value,
there is no effect on the image.
Note: If e.g. an adjustment to reduce the level of red in the image is required, select a higher number for
the (input) Colour Temp in the Colour menu, or a lower number for the Native Colour Temp in the
Output menu.
3.5.8. Output Config
This Menu provides items to configure the output ports.
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 colour.
Optimize for Display
Settings: DVI forced, Optimized, DVI/HDMI
Internally, the display interface processes data at a full ten bits per colour. A resolution of ten bits per
colour is provided for the VGA output. The colour 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 colour 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 colour depth is determined in the same way as when set to
DVI/HDMI.
DVI Colour Space and DVI Range
The colour space of the DVI output port can be set to RGB or YPbPr.
The range can be set to Default, Limited, and Full. When set to Default CEA 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 behave as expected, e.g. because the HDMI display is not evaluating
AVInfoFrames 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.
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 discussed in paragraph 3.5.3.
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.
