How to get Stereo view on windows without plug in VR devices or VR Preview

Hey guys, I’m doing a project on PC. I need to show a windowed VR distorted stereo view, at resolution of 1920*1080. I want to do it without plugin an Oculus or Vive, and I need to package the game rather than in editor like VR Preview mode.

I have tried console commands: Stero On, HMD mirror mode 0. None got recognized or reacted by Unreal Engine 4.12 in Windows 10.

Anyone has some ideas how to do it? Thanks so much!
