Resolution refers to the number of pixels displayed on the screen. For example, a resolution of 3200*1440 means that the number of pixels on the long side is 3200, and the number of pixels on the short side is 1440.

Usually, HD refers to the resolution of 1280*720, FHD refers to the resolution of 1920*1080, QHD refers to the resolution of 2560*1440 (often said 2K screen), UDH refers to the resolution of 3840*2160 (not often said 4K screen). The result of their multiplier is the screen pixel. However, with the popularization of the full screen of mobile phones, the length of the mobile phone has been gradually lengthened, so the actual value of the long side at the end will be greater than the corresponding number of pixels.

HD, FHD, QHD, UDH in screen resolution are displayed gradedly
