    Hello,

    Getting similar issue. Tried on Unity 5.6.3f1 and 2017.3.0f3 on iOS 11.2

    App crashes when changes to new scene.

    in iOS 11.2.5 with Unity 2017.3.0f3 the crash still happens on Metal, but external Display works using OpenGL ES 2 or 3 - only performance seems VERY slow oven on iPad Pros. And the crash issue described by SWIGUY15692 still happens.

    Have you tried building it with metal support disabled, just good old GLES?

    Getting similar issue. Unity 2017.2.0f3 and iOS 11.2 on an iPad Pro 10.5"

    Unfortunately I just picked up the adapter after I made the switch to 11.2 and didn't test on 11.1

    App crashes immediately upon attempting to launch while HDMI adapter connected, however if I launch the app without the adapter first, I can plug it in and everything works as it should.

    With iOS 11.2, Unity crashes as soon as an external display is connected. Happens also on iPad Pro (tested with 12.9" ML0FD/A)
