I have a Sony KV40XBR800 and use the component output from my Pace 550hd STB. The STB allows setting the format from the component output. My question is simple: How does the TV recognize which format is being used. If the TV sees a 1080i format does it automatically assume a 16:9 format? If so how would this interface, at least on this TV work, with say the Sony 200HD?? SAT receiver which allows cropping of a 16:9 format to fit a 4:3 display. The STB allows one to zoom the HD 16:9 1080i format but converts it a 480p 4:3. i assume that 480p can be a native resolution for this TV but not sure. The set seems to act that way since DRC is not functional when doing this.
