Enable frame lock on slave devices | Nvidia 2 guide

NVIDIA Frame Synchronization Under Linux

9.Enable frame lock on slave devices.

nvidia-settings -a myserver:0[gpu:1]/ FrameLockEnable=1

nvidia-settings -a myslave1:0[gpu:0]/ FrameLockEnable=1

nvidia-settings -a myslave1:0[gpu:1]/ FrameLockEnable=1

10.Toggle the test signal.

nvidia-settings -a myserver:0[gpu:0]/ FrameLockTestSignal=1

nvidia-settings -a myserver:0[gpu:0]/ FrameLockTestSignal=0
