I recently insalled a Vizio V505-JO9 television to my existing UVerse setup. The images on the screen associated with the Vizio Home and associated screens are crystal clear. After programming the UVerse remote to operate the televion, the Uverse images all seem to have a ghost appearance, while the Vizio images remain crystal clear. My television is connected via coaxial cable. Would connecting via HDMI improve the Uverse images?
