Leveraging Frame Lock/Genlock in OpenGL
With the
GLX_NV_swap_group
extension, OpenGL applications can
be implemented to join a group of applications within a system
for local swap sync, and bind the group to a barrier for swap
sync across a frame lock group. A universal frame counter is also
provided to promote synchronization between systems.
Frame Lock Restrictions
The following restrictions apply when enabling frame lock:

All frame lock display devices that are connected to the same
Quadro must have the same display-mode timings.

All display devices set as the frame lock client must have the same
refresh rate as the frame lock server (master) display device. If a House
Sync signal is used (instead of internal timings), all client display devices
must have the same refresh rate as the incoming house sync signal.
 All X Screens (driving the selected client/server display devices)
must have the same stereo setting. Refer to the Linux README.
TXT
fi le for instructions on how to set the stereo X option.

The frame lock server (master) display device must be on a Quadro
on the primary connector to the Quadro G-Sync II option card.

If connecting a single Quadro to a Quadro G-Sync II
option card, the primary connector must be used.
 In con fi gurations with more than one display device
per Quadro, we recommend enabling frame lock
on all display devices on those Quadros.
