The HD resolution list displays various HDTV display formats with equivalent screen resolutions such as 480p (720×480 progressive), 480i (720×480 interlaced), and so on. Choose a format that gives you the display result you want.
Note: Typically, progressive formats provide a more stable picture with fewer flickers. Refer to your HDTV owner’s manual for a list of supported display formats.
