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 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, e.g. 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 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.
