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.
