A:Answer I am watching over the air broadcast using "Native", "Movie" mode. Movie mode gives clear picture quality as compared to others in this TV. You may then use in "Movie" mode some customization by pressing "Menu" button on remote, Select "Picture" and here you may adjust little bit of "Sharpness", "Brightness", and other options as you desire.
As I mentioned in my early post in reviews; "I use antenna to watch over the air programing. I have noticed one thing; Channel 2,4,11,13 and 50 are shown in 1080i whereas Channel 5 and 7 are in 720p. if you are a cable customer you may experience 1080p but I don't know for sure. Maybe this is how each channel is broadcasted not a TV issue. But even with 1080i and 720p broadcast I don't see performance or picture issue."
Hope this helps!! Have some patient!! You will figure it out :)
