See Using the OpenGL Extensions (page 55) for instructions on how an application can use the extensions to accomplish swap sync.

Setting Up Genlock +

Frame Lock

The procedures in the previous two sections describe the more common uses of the Quadro G-Sync II option card. A third use involves a combination of genlock and frame lock.

In this setup, a set of client systems are connected to a system that is designated as the server, as described in How To Set Up Frame Lock. The difference is that the server system is genlocked to an external house sync, as described in How To Set Up Genlock.

1.Follow the instructions under How To Set Up Frame Lock and then attach an external sync source to one of the systems included in the frame lock group.

2.Check the Server check box of the display that is connected to that same system.

3.Check the Use House Sync if Present check box.

4.Enable synchronization by clicking Enable Frame Lock.

As with other frame lock/genlock controls, you must select the signal server while synchronization is disabled.
