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 applicationssuch as virus scan, backup and archiving applicationsprior

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.
