Custom made HMD

I’m trying to build my custom HMD (2 screen setup 1080x1200 - screens connected to controller with HDMI and micro USB inputs, arduino used for head rotation).
So far no luck to find any readable info about how to hookup all this in unreal engine (arduino i have managed to connect and it works - i can rotate cube in game). I was wondering, is it possible to somehow tell unreal engine to play on those screens? Im not interested at this point to make my helmet work with other games just this one. Theoretically this must be “easy” done, right? Help, I’m stuck :slight_smile:
