After purchasing a headset for your Phone there are two app solutions that allow you to divide a selected windows application into two images (stereoscopic)
TriDef 3D Is a program that catches your app/game steam execution and automatically makes it stereoscopic.
RiftCat -Wasn’t able to get the connection working
TrinusVR – Was able to run it. Problems with the program crashing. Problems with tracking. No need to install SteamVR; SteamVR overheats my PC
