nDisplay multiple computers black screens

I’m trying to get nDisplay working on multiple PCs, but keep getting black screens. I have three screens that I’m using which are connected to the nodes as follows:

node_1 is screen 1, on computer A

node_2 is screen 2, on computer B

node_3 is screen 3, also on computer B

Now, from computer A, I can comment out nodes 2 & 3, and node 1 will run fine. I can also comment out node 1 and make node 2 the master, in which case nodes 2 & 3 run fine (displaying on computer B, but run from nDisplay on computer A).

So basically, I can run computer A and computer B fine individually, but if I try to run them both at the same time, I get black screens on both computers that don’t crash, they just stay black forever. I’m always running it from computer A since it has the vive connected, so I know it’s not the IP addresses or a firewall issue. I’ve also checked that there are no spaces in my file path and that the screens are sized properly. Anyone have any ideas as to what’s wrong or things I can try to get this up and running??
