I just checked. my local ABC and FOX are 720p, but NBC and CBS are 1080i Idk why, but this hasn't really seemed bad to me. Maybe my TV has been upscaling and that's why I don't notice? Reading around it's unclear if they broadcast above 720p anywhere, even over cable: https://en.wikipedia.org/wiki/American_Broadcasting_Company https://en.wikipedia.org/wiki/American_Broadcasting_Company . Maybe the cable companies upscale? Whatever the case may be, I'd rather have 720p for free than have to pay.
