Ive got a panny tx36pb50 and am wondering if there is a way to alter the screen size - i know about the geometry option. On my older tv u could alter the screen position and even the sides and corner bowing? Ive looked through the manual and cant find it as an option. I cant believe a TV like this would not have this as an option. So anyone had any experience with pannys or possibly an engineer type? The problem i have is the screen appears slightly stretched into the corners & was hoping to maybe sort it.
