Hello everyone!
I’m currently working on launching a shipped project with an nDisplay setup, but all I get is a persistent black screen, even though it runs perfectly within the editor. 
I’d really appreciate any insights or suggestions from anyone who’s experienced similar issues!
Here is my .bat file that is used to launch everything :
@echo off
start Ndisplay_Simple.exe -game -messaging -dc_cluster -nosplash -fixedseed -NoVerifyGC -noxrstereo -xrtrackingonly -RemoteControlIsHeadless -StageFriendlyName="Node_0" -MaxGPUCount=2 -dc_cfg="NDisplayConfig_Simple.ndisplay" -dx11 -dc_dev_mono -dc_node=Node_0 Log=Node_0.log -ini:Engine:[/Script/Engine.Engine]:GameEngine=/Script/DisplayCluster.DisplayClusterGameEngine,[/Script/Engine.Engine]:GameViewportClientClassName=/Script/DisplayCluster.DisplayClusterViewportClient,[/Script/Engine.UserInterfaceSettings]:bAllowHighDPIInGameMode=True -ini:Game:[/Script/EngineSettings.GeneralProjectSettings]:bUseBorderlessWindow=True -ini:Input:[/Script/Engine.InputSettings]:DefaultPlayerInputClass=/Script/DisplayCluster.DisplayClusterPlayerInput -unattended -NoScreenMessages -handleensurepercent=0 -UDPMESSAGING_TRANSPORT_MULTICAST="230.0.0.1:6666" -UDPMESSAGING_TRANSPORT_UNICAST="[CENSORED]:0" -UDPMESSAGING_TRANSPORT_STATIC="[CENSORED]:9030" -ExecCmds="DisableAllScreenMessages" -windowed -forceres WinX=0 WinY=0 ResX=3840 ResY=1080 -CONCERTRETRYAUTOCONNECTONERROR -CONCERTAUTOCONNECT -CONCERTSERVER="Ndisplay_Simple_MU_Server" -CONCERTSESSION="MU_Session" -CONCERTDISPLAYNAME="Node_0" -CONCERTISHEADLESS -DPCVars="Slate.bAllowNotifications=0,p.Chaos.Solver.Deterministic=1" -useallavailablecores

He is my nDisplay config file :
