I'm experiencing white vertical shadowing (that's the best way I can describe it). ie. when a movie show its credit on the black screen at the end of its show, the white words cast a vertical shadow. I can see it in the movies too. A scene in a movie I was watching on Netflix last night; the actor was driving downtown at night on a major highway and every street light he past cast a slight vertical beam of light from top to bottom of the TV. Did I screw up my settings. I have to admit I was playing around with the settings...but I don't know where I when wrong. Can anyone help?
