The Quadro G-Sync card, because it provides more accuratesynchronization, typically requires about 30 seconds to achieve stereo sync.• Connection Status• In/Out or Out/In is the normal indicator for client devices.• In/In indicates that there is no connection at any of the connectors of the clientdevice, or the system is not selected as a server or client, and is not Frame-lockenabled.Swap SyncThe application controls synchronization of buffer swaps (swap sync) betweenapplications. Proper connection and synchronization of the timing signal are required forproper synchronization of buffer swaps.See “Using the OpenGL Extensions” on page 22 for instructions on how an applicationcan use the extensions to accomplish swap sync.
