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
