Hi, I just installed the GeForce GTX 1050ti from EVGA, after having a 750ti from msi, and Oculus now only displays what's on my monitor. I've uninstalled my driver and reinstalled, I've updated to newest drivers, I've uninstalled Oculus, I've done nearly everything I could think of. Below are my specs, as in GeForce Experience. I'm running on Windows 8.1. If any more is necessary, just ask.
EDIT: Friend fixed it, caps on my graphics card hid the HDMI slots that weren't on my 750ti. Before, I just had to plug the HDMI into my motherboard, but this time had to be plugged into my graphics card as normal.
