Im 99.9% sure ALL 720P Tvs display at 1080i. The manufacturer rates them by the P rating for some reason. I have a Vizio TV and on the box (and in the store on the sales tag) it says diplays in 720P but in the manual it says "Signal Compatibility: 480i (SDTV), 480P (EDTV), 720P (HDTV), 1080i (HDTV).
