Hi,   
I got a rift and every Oculus app works fine.   
When I start DCS, the Oculus turns on (white light and "DCS.exe is loading").   
DCS Window pops open, but all I see is black, no loading bar, no sound, nothing.   
I tried switching the HDMI Output (SLI GTX 970s)   
Anyone got any suggestion? I already reinstalled DCS, turned all Settings to LOW, tried every guide out there that I found.   
One thing to mention, I move my PC from one room to another. Before the move it worked!   
Only difference: I have now connected 1 monitor less, than in the other room.
