Oculus Rift/HTC Vive: 1080 x 1200 per eye
Samsung Galaxy S7: 1440 x 2560 total screen
Sony Xperia Z5 Premium: 2160 x 3840 total screen
But here’s the thing.
Phone screen resolution has to be cut in half in one dimension to deliver the image to each eye.
Samsung Galaxy S7: 1440 x 1280 per eye
Sony Xperia Z5 Premium: 2160 x 1920 per eye
And, in fact, it’s less than a straight divide-by-two, because the images aren’t exactly cut in half, they’re rounded for the VR lenses:
Is is that why the screendoor effect is so pronounced on the Gear VR over the Rift and Vive? Because the screen resolution for the Gear VR is actually lower per eye?
If that’s so, the case for phones with 4K screens for Mobile VR has just been made.
And if Sony doesn’t capitalize on that with the Xperia Z5 Premium, it’ll be their biggest blunder of 2016.
