    How does the number of screen pixels with the new Ultra HD 4K televisions compare with computer monitors? The same?

    4K UHD is a resolution of 3840 pixels × 2160 lines (8.3 megapixels, aspect ratio 16:9) and is one of the two resolutions of ultra high definition television targeted towards consumer television, the other being 8K UHD which is 7680 pixels × 4320 lines (33.2 megapixels). 4K UHD has twice the horizontal and vertical resolution of the 1080p HDTV format, with four times as many pixels overall.[1][4]

    A rough estimate, by eyeballing these numbers, is that those 4K TV manufacturers with a PPI (pixels per inch) of 80 would be near the head of the pack.

    A rough estimate of PPI (pixels per inch) for computer monitors would be maybe 90.
    For HDTV's, the PPI runs between 35 and 116. The list doesn't specifically mention "4K UHD". The one with the PPI of 116 is this: 1080p/1080i on a 19" screen (116). 1080P isn't 4K UHD. So there already exists an HDTV that is superior to 4K UHD, based on PPI.


    The amount of content able to be displayed with1080P is limited. And with 4K UHD, virtually nonexistent.
