Resolved Would UI elements' size be the same if iPhone 6+ used native resolution panel?

    So iPhone 6 plus uses virtual resolution 1242x2208 and then downsamples it into 1080p.

    In this article he claims:

    I read again and again and still have no idea why he can claim that.

    401ppi on 1080p in 5.5"
    461ppi on 1242p in 5.5"

    diagonal px of 1080p is 2202.9/401=5.49
    diagonal px of 1242p is 2533.3/461=5.49

    Is that the reason why he says that UI sizes will remain physically the same even if Apple used 1242p panel?
    Thanks.

    It would be the same because it would still be a 5.5" display. So a native resolution panel would have a greater pixel density, which would result in UI elements appearing to be the same size

    I see... That was that simple...
    So that's what downsampling was meant to be instead of downscaling? I mean, iPhone 6 plus' panel is downsampled and works as if it has 1242p workspace?
