Hi!
For some reason I can’t active multi gpu setup. I am using two rtx quadro 6000 with nvlink bridge and 3 monitors (no mosaic), but for some reason ndisplay ignores commands (gpu_node=1 in config and -MaxGPUCount=2 in launcher) regarding using the gpu I need. At one moment I could use it and it was working fine. Then it started to using gpu which needs to render certain monitor and now it just works on gpu 0 no matter what I wright in config 
In Nvidia control panel I used and “activate all displays” and “sli disabled” but it seems it didn’t matter. Please help
Same boat 
because if you have the nvlink on the cards they act as 1 gpu. Remove nvlink to get access to individual gpu outputs totally 4 per gpu.
