Chapter 02 : NVIDIA Graphics-to-SDI
Changing Video Formats
When changing any of the SDI settings, visual disturbances might occur as the video
resets to the new settings. To prevent such disturbances from being visible to the public
or from being recorded, observe the following sequence when making changes to any
SDI setting:
1 Stop the live broadcast (go off air)
2 Change video format or SDI settings
3 Verify video quality
4 Resume the live broadcast
When Using the Control Panel
NVIDIA recommends the following
Set the desktop to the same or higher resolution than the SDI output for better image
quality.
Close all background applications—such as virus scan, backup, and archiving
applications—before starting the SDI output and going on air.
Close the Display Properties panel before going on air.
When running multiple OpenGL applications, tearing may occur if the applications
are not synchronized.
In general, NVIDIA does not recommend running multiple OpenGL applications
when starting the SDI output or when going live.
Running Multiple OpenGL Applications
To maximize the system resources and bandwidth available for converting graphics to
SDI output, NVIDIA recommends broadcasting only one OpenGL application at a time.
