I’ve read on 4.27 Unreal Engine Documetation that we can use nDisplay to render multiple application instances to multiple displays. I’ve followed the instructions and managed to connect 2 PCs to run exact same project. But when I used Switchboard to render output from each PC to one specific screen it didn’t work. If anybody has done it before, could you tell me how to do it properly? I’ll appreciate it very much!
