I followed the above video. Getting the display on monitor. Getting the motion with respect to OCULUS RIFT Tracker. But I am unable to see the same in my HMD.

#Note 1: I have seen the library content from oculus software. so HDMI is fine.(the demo content from oculus software ie the scenery, Alien standing in front etc)
# NOTE 2: I ve also applied the settings in oculus>general>allow from unknown resources
#Note3 : I dont have a compatiple GPU(I am having Nvidia GT 730) Is this a problem.

I also tried vizconnect. Added oculus rift tracker(works fine as i can see display viewpoint movement on monitor)
but adding oculus display doesnt show anything on oculus display.

i get winwiz error. Is GPU causing this??
Or is it something else ??
Please help
