Querying the Frame Lock Capabilities of a System
1. Query the number of Quadro G-Sync II devices on
the system by passing
NV_CTRL_TARGET_TYPE_
FRAMELOCK
to
XNVCTRLQueryTargetCount()
.
2. 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.
3. 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:
1. Set the frame lock master display on one of the Quadros
using the
NV_CTRL_FRAMELOCK_MASTER
attribute.
2. Set the rest of the display devices as slaves using the
NV_CTRL_FRAMELOCK_SLAVES
attribute.
3. 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.
4. 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
.
5. Set
NV_CTRL_FRAMELOCK_SYNC_DELAY
as appropriate for each
Quadro G-Sync II device.
Most likely, you want 0.
