I'm using 173.14.05 of the driver with two Quadro 5600s and a G-Sync option.
I have a Genlock signal going into the G-Sync and I've configured the G-Sync to receive (and use) this house sync (i.e. its a master and uses House Sync). I also put probes on the genlock signal and the Vsync signal on the output DVI cable.
In software, I'm then waiting on this to return timing as "true":
XNVCTRLQueryTargetAttribute(dpy, NV_CTRL_TARGET_TYPE_GPU, 1, 0, NV_CTRL_FRAMELOCK_TIMING, &timing)
It is my understanding that after this returns true, the video card VSync should be sync-ed to genlock, however, comparing the Genlock signal and the VSync on the DVI, they sometimes are not yet sync-ed. It may take another 15 seconds for them to be sync-ed.
Is there some way to make sure that we are actually genlocked?
