    So, by comparison, here's the Note 7's:

    Quad HD 1440 x 2560 pixels
    515 ppi approx.

    Okay, the 5.5" 7 plus is 401 ppi. Compare that to the 5.7" Note 7, which has 515 ppi

    Yes, it is a larger number. I'll grant that. The difference is perhaps unobservable, so let's break it down. ( the x by y pixel size is just a function of screen size and ppi).

    On the iPhone the RGB pixel is 401 ppi, or 63 microns (0.063 mm)

    On the Note 7, the green pixels are 515 ppi, and the R & B pixels 366 ppi. That's lower than the iPhone 7 plus; 50 and 70 microns respectively.

    That gives a RMS average ppi of 298, a bit lower than the iPhone. All this has to do with the screen selection.

    In the end it all means nothing. The minimum viewing distance for all colors combined and 20/20 vision is about the same for each phone : 8.5 inches.


    From DisplayMate.

    Oh my. I wasn't trying to "pick a fight." I merely stating that I expected Apple to be "keeping up with the Joneses." I hope the owners of the latest/greatest iPhones are happy. Admittedly, I am not so happy with Samsung anymore.

    I didn't think you were picking a fight.

    One reason why I like Apple is that there usually are engineering reasons behind their specs.... And less marketing hype.

    Some viewed the term 'Retina display' was a marketing hype word, but it was based on visual acuity limits.

    Specifications beyond those limits, especially in only one color, is questionable.

    I wonder if they are saving for a better display with the next version. I keep hearing the rumors Apple will forego the 7s next year and go straight for 8. Which would make the 7 little more than a hold-over until 8 arrives.

    Since I'm not due for an upgrade until next year, I'll hold on to the 6 Plus for now. It still works like a dream. I'm more excited for iOS 10 and soon, MacOS Sierra!
