    In light of all these varying HiDPI display compatibilities, the development of applications and the changes in monitor pixel density have been under great speculation. Until recently most monitors typically had a pixel density* of 96 ppi. Various different company’s monitors were designed to match the display size (inch size) with the resolution, therefore most OS and applications were also made based on this 96 dpi standard.

    4K is not standardized description of a number of physical pixels. It’s an approximation of the number of pixels wide something is (as opposed to the previous convention of how many pixels tall as in 480p, 720p, 1080p, etc.). Something with somewhere around 4000 pixels wide will be called 4K. So you have a variety starting from 3840 pixels up to at least 5120 pixels on “ultrawide 4K” displays, broadcasts, or video.
    Display resolution of a computer monitor, tablet, laptop, smartphone or any other display device is the number of distinct pixels in each dimension that can be displayed.

    Ever since Vista, Windows has been gradually advancing the HiDPI compatibility of its OS and development platforms (multi-monitor compatibility was introduced from Windows 8.1). However there are still many applications that are not compatible or fully compatible due to the following reasons. In these cases, an application created in the previously standard way will be forcibly enlarged / shrunk by the OS, causing it to become blurry. Furthermore some applications may display without blurring, but the display size will be reduced.

    The takeaway should be that at a certain point, a physically smaller display requires physically fewer pixels to remain usable at HiDPI (assuming similar view distances). Cramming “4K” pixels into that small of a space is worse than just using fewer pixels, even if you don’t get the marketing-friendly 4K term.
