Querying the Frame Lock Capabilities of a System
Query the number of Quadro G-Sync II devices on the
system by passing NV_CTRL_TARGET_TYPE_FRAMELOCK to
XNVCTRLQueryTargetCount().
Query the Quadros attached to each Quadro G-Sync II device by
querying the NV_CTRL_GPUS_USING_FRAMELOCK attribute for each
Quadro G-Sync II device.
Query the enabled (available) displays on each Quadro using the NV_
CTRL_ENABLED_DISPLAYS attribute.
Confi guring the Frame Lock Group
This must be done while frame lock is disabled on the Quadro G-Sync II
device:
Set the frame lock master display on one of the Quadros using the
NV_CTRL_FRAMELOCK_MASTER attribute.
Set the rest of the display devices as slaves using the NV_CTRL_
FRAMELOCK_SLAVES attribute.
Set NV_CTRL_USE_HOUSE_SYNC to NV_CTRL_USE_HOUSE_SYNC_
TRUE or NV_CTRL_USE_HOUSE_SYNC_FALSE on the master Quadro
G-Sync II device, depending on whether or not you will be using a
House Sync signal.
This refers to the G-Sync device that is attached to the Quadro that
contains the display device currently set as the frame lock master.
Set NV_CTRL_FRAMELOCK_POLARITY for each slave Quadro G-Sync
II device in the cluster.
Most likely, you want NV_CTRL_FRAMELOCK_POLARITY_RISING_
EDGE.
Set NV_CTRL_FRAMELOCK_SYNC_DELAY as appropriate for each
Quadro G-Sync II device.
Most likely, you want 0.
