InfoComm International has released a new standard for sizing displayed images for audiovisual systems: ANSI/ INFOCOMM V202.01:2016, Display Image Size for 2D Content in Audiovisual Systems. It determines required display image size and relative viewing positions according to two defined viewing needs: basic decision making and analytical decision making. These two viewing categories are derived from ANSI/INFOCOMM 3M-2011 Projected Image System Contrast Ratio (PISCR). Image height, image resolution, and the size of image content are all prescriptive elements when determining required image size. The standard also addresses closest and farthest viewing distances, as well as relative horizontal and vertical viewer locations.
