FRAMELOCK_SLAVES

NVIDIA Quadro G-Sync II User Guide

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.

Configuring 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_ 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.
