How to Set Up the SDI Output

This section describes how to set up SDI output on the linux system. There are four
methods of using the SDI output. Each are mutually exclusive–you cannot use the SDI
output in more than one mode at a time.
• Clone mode: In Clone mode, the SDI output is a clone of the display output. This is the
default mode. You can switch directly to Dualview/Twinview mode while operating
the SDI output.
See "Basic SDI Setup Under Clone Mode" on page
• Dualview mode (TwinView): In Dualview mode the SDI device is treated as a regular
flat panel and you can define one large desktop that extends from the display to the
SDI output. This lets you move windows between the SDI output and the graphics
(DVI) display part of the extended desktop.
See "Basic SDI Setup with X‐window or under Dualview Mode" on page
• X‐screen mode: You can display the SDI output on an x‐window. In X‐screen mode the
SDI device is treated as a flat panel that gets its own X screen.
See "Basic SDI Setup with X‐window or under Dualview Mode" on page
• OpenGL application control: The SDI application programming interface allows
OpenGL applications to have full and exclusive control of the SDI output.
To use this mode, run an application that uses either SDI APIs to make use of the SDI
device.

Basic SDI Setup Under Clone Mode

To ensure proper operation, NVIDIA recommends the following -
• Set the desktop resolution to be the same or larger than the SDI output for better image quality
• Stop background applications—such as virus scan, backup and archiving applications—prior
to starting SDI output and going on air.
• Close the control panel before going on air.
• When running multiple OpenGL applications, synchronize them, otherwise tearing may occur.
