Examples for
Display Formats
Modern technology has given rise to a number of different display formats to address the needs of various devices and users. Request information from Wolfram|Alpha about screen resolutions, such as 1080p or older standards like VGA, for computer monitors and LCD screens, including comparisons. Get similar data for paper sizes used in printing, such as A4 paper, or for photography print sizes, such as an 8x10 photograph.
Display Resolution
Find the constraints on other properties of these displays, such as pixel count, aspect ratio and diagonal length of the screen, due to pixel resolutions of various displays.
