Thanks @Lea
I tried the delay setting but that did not help. Now when the Video Wall mode is active I only have one display that works even though the others say they are connected. The only way I could get it to work is to de-activate the video wall mode. Then all of the 5 connected devices would have an image. Otherwise they were black with the exception of one that was the far right end display on the video wall.
Attached is the diagnostics file requested. I still get the same issue of the disconnect error message on reboot even with the video wall is not active.
