I just received my Pimax 4K and installed PiPlay 188.8.131.52 from pimaxvr.com. The installer stated everything to be "OK" or "Good enough".
After plugging in the device PiPlay states that USB and HDMI are connected but nothing else happens. Following the UserGuide I would expect the program to show the serial number and firmware version etc.
Replugging the USB does switch the USB and HDMI state from "Unrecognize" & "Disconnected" back to "Connected" but still nothing else happens. Same goes for turning the device off and on.
My GFX-card has added the Pimax's screen to my desktop though. I can see my desktop background and I can move open windows over to the Pimax's screen. The orientation is wrong though and is rotated by 90°. I can change that in the display settings though.
At some point I updated my GFX drivers to the newest version, but no change in behavior.
The LED on the headset is blue, unless it is initializing during which it is green.
Turning off the screen in my graphics-card's display settings will turn the LED red.
I really have no idea what I am missing here.
My System Specs:
Windows 7 SP1
Intel Core i5-4690K
nVidia Geforce GTX 960 (Driver: 390.77)
16 GB RAM
