To begin calibrating your viewer profile, open the viewer profile generator on your desktop browser. Scan the QR code on the tool’s homepage using a smartphone:
When the VR calibration scene opens on your phone, tap the screen once to show it in full screen. If you see a popup that says "Mobile device display properties unknown", then the phone cannot be used for calibration because the physical screen size info is unavailable.
With the scene displayed full-screen on your smartphone, insert the smartphone into your viewer. Proceed to the next step to continue calibrating your viewer profile.
