> 50 is retina quality. Something must be off here. My 4k 40″ screen at 30 inches distance gives 70 ppd. It works well for reading, but I don't think it fits "retina quality". Retina would be above 100. BTW, half of that (35ppd) would be an uncomfortable 1080p on 40″. Which makes Quest Pro even worse. The only thing I think might make it better is that unlike on static screens head motion could add a nice smoothing effect to the picture, which might potentially lower the required PPD.
