I have the format in 1080i + original unaltered. I made a test jpeg that was exactly 1920x1080. When I display it, it does not fill the entire screen. I have a black border around the entire picutre. If I turn the TV to the E channel first then display the horizonal gets stretched a bit more but there is still a black boarder around the entire picture. Has anybody gotten a 1920x1080 jpeg to fill the entire screen or is just a feature/limitation of the HR23 and or Tversity?
