I just bought the LG 47LS4500 today and I had a quick question about manually setting V/H adjustment. With my current TV package I only get about 3 HD channels and I have no plans on getting anymore for about a year when fibre is available in my area. When the TV is receiving a signal from a non HD channel, I have to adjust the video display to 'Cinema Zoom 16' so I'm not watching a 40" image on a 47" TV. When I set the TV to Cinema Zoom 16, the horizontal and vertical adjustments are way off. The top and left sides have about a half inch of black. The bottom is off the screen and the right side is perfect. Is there a manual setting to make these non HD signals fit the screen properly?
