    For 55" 1080p Resolution :
    Diagonal resolution : SQRT (3686400 + 1166400) = SQRT (4852800) = 2202.907
    Display size = 55"
    Hence, Pixel density = 2202.907/55 = 40.052

    For 55" 4K UHD Resolution :
    Diagonal resolution : SQRT (14745600 + 4665600) = SQRT (19411200) = 4405.814
    Display size = 55"
    Hence, Pixel density = 4405.814/55 = 80.105

    Hence, 4K UHD display will have higher PPI than 1080p Full HD.
    Are you sure? This action cannot be undone.

    From above calculations, it's clear that 4K is for larger displays. And yet people want FullHD in their mobile phone.
