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.
