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 confi gurations with more than one display device per Quadro,
we recommend enabling frame lock on all display devices on those
Quadros.
