Okay - Solved this. Here is how to configure 4k screen for any VR viewer.Thanks for the useful info now 3 years later. Can you elaborate how you managed to create a QR code for cardboard that works 4k full size? I tried this with the cardboard code generator to get shapes right with xpreria xz 4k mode and Gear VR.
What ever I do, the VR image stays tiny on the bottom. I inputted my current PPI of 802 for the generator and all right info, even tried 200 ppi and 1600ppi, to see there is no change to the image location on VR players (still tiny at bottom).
As your QR still works but its not perfect for these lenses. A helping hand would be appreciated!
Trying my luck here now years later. Hope you're doing good in these times where VR is more needed than ever.
1. Go to: https + : + //: + wwgc + firebaseapp + .com (Sorry cant post urls as a newbie user.)
2. Follow the instructions and correct the view so that it looks perfect on your headset (all the lines are straight etc.)
3. Then set the "Screen to lens distance" and "Inter-lens distance (mm)" to exactly the double it would have been normally. Screen to lens distance: 41 -> 82 and Inter-lens distance 60 -> 120. - For gear VR Distortion coefficient k1 is 0,050 and k2 0,2.
4. Create the QR code and scan it with any 3rd part QR code reader into your cardboard app. (cardboards own qr code reader gives a lot of errors, but this works)
Here is a working profile for Sony xperia XZ that is set to 4k all the time with abd command. Optimized for Samsung Gear VR .
