Dont confuse supports and native. For example, my tv supports all of the above but it's native resolutions are 480I, 480P and 1080I. It will accept a 720P signal but my set will downconvert it to 480P. Therefore, it is to my advantage to upconvert all HD signals to 1080I before it is sent to my TV. You need to read your manual and see what your sets native resolutions are and what it does with those that are not native.
