NVIDIA QUADRO G-SYNC II

6. Set NV_CTRL_FRAMELOCK_SYNC_INTERVAL as appropriate if you are
using a house sync.
Most likely, you want 0.
Enabling/Disabling Frame Lock
1. Enable frame lock on each Quadro by setting NV_CTRL_
FRAMELOCK_SYNC to NV_CTRL_FRAMELOCK_SYNC_ENABLE.
2. (Optional) Set NV_CTRL_FRAMELOCK_TEST_SIGNAL to NV_CTRL_
FRAMELOCK_TEST_SIGNAL_ENABLE followed immediately by
NV_CTRL_FRAMELOCK_TEST_SIGNAL_DISABLE (on the Quadro that
contains the master frame lock display).
This guarantees accuracy of the Universal Frame Count
(as returned by glXQueryFrameCountNV()).
3. When you are done, set NV_CTRL_FRAMELOCK_SYNC to NV_CTRL_
FRAMELOCK_SYNC_DISABLE on each Quadro to disable frame lock.
During operation you can also query any of these
on each Quadro or frame lock device:
� NV _ CTRL _ FRAMELOCK _ PORT0 _ STATUS
� NV _ CTRL _ FRAMELOCK _ PORT1 _ STATUS
� NV _ CTRL _ FRAMELOCK _ HOUSE _ STATUS
� NV _ CTRL _ FRAMELOCK _ SYNC _ READY
� NV _ CTRL _ FRAMELOCK _ STEREO _ SYNC
� NV _ CTRL _ FRAMELOCK _ ETHERNET _ DETECTED
� NV _ CTRL _ FRAMELOCK _ SYNC _ RATE
� NV _ CTRL _ FRAMELOCK _ TIMING
