[Bug]Stereo mode forced on when in fullscreen (Oculus Rift)

I have recently run the “stereo on” console command and now every time I run the game it’s turned on by default. When I turn it off I’m unable to change the resolution of the game (console: setres 2560x1440x32 f) but it works if I’m in window mode. If I go back in fullscreen its turned back on.

This problem doesn’t happen on other computers where I never ran the stereo on command.
What can I do? Is there a setting saved in windows registry somewhere I can delete?

I’m running windows 8 with UE 4.2.1 and have my oculus rift completely disconnected from my computer.
