[QUOTE="knutinh, post: 69217, member: 14776"] You seem to like these tall displays! =) We've got a 0.9 AR display with 1.33:1 AR video in and 1.33:1 desired AR (no visual stretching). I cant see that the supplied info tells whether to use source cropping, so Ill assume that it isnt desired. 720x576 pixels representing a 4:3 visual image should be presented on a 1024x768 pixel display that has visual dimensions 0.9:1. It is evident that we need som goode ol' black bars. (4/3)/(0.9/1) = 1.4815 This is the visual relation between source video and output display. In order to fit a "wide" (4:3) image inside the nearly rectangular 0.9:1 monitor we need to fill the height with information only 1/1.4815 of the available height, or 67.5%. When there are 768 available pixels, we should employ 518 vertical pixels and 1024 horisontal ones. video source rect : [1 720 1 576] display rect : [1 1024 125 643] -k [/QUOTE]
