I recently got a Samsung 50' DLP 720p television. After reading the forums on here I went into the service menu and set 4:3 to off because I hated how non HD stations looked strechted Since then when ever I am on a station that is non HD there is a blue line down the left hand side about 1 inch over from where the picture is. The line disappers on the HD stations as well as in the guide and menus of the DVR.
What is this from and how do I stop it? I have tested DVI - HDMI and Component cables thinking that may help but still no luck.
