The HDTV image is stunningly different than a normal television picture. Not only the obvious differences like no noise, shadows or interference. The picture actually looks 3D. Items on the screen stand out from others, and some are razor sharp. I was watching a scene with a man and a woman. I could actually see fine wrinkles on the man's face, and even saw freckles on the woman's shoulders.
People look different.
You just haven't seen actors and actresses the way that they actually look in person until you've seen them in High Definition. Setup is easy. The menu is very easy to figure out and make changes. If I would have had my satellite dish connected, and it found any HDTV signals from the satellite, it would have added them to memory as well. But on channel 3 was Fox Chicago, our local Fox station.
