nDisplay onClusterEvent don't work

I use nDisplay for multi-display on single pc.
Cluster event i need for load sublevels.

I made cluster listener like here

but i try to send from cluster node and from launcher but event doesn’t come

UE version 4.22.1

Can you solve it? If so, how can you do it? Thank you.

Hi, did you setup the multi-display on single pc? I can’t figure out how to tell the nDislpay which window to show on which physical monitor. Both windows start in the same monitor, whereas my extended one stays empty. Is it the setting inside nDisplay config file? I used an example config “wall_curved_3x2”. I am working with UE4.21
