Have a Samsung HL-T4675S 46" DLP TV that seems to have some significant overscan. I really notice it on the picture from my Dish 622 on HDMI input. I called Samsung and they said certain models have the capability to adjust this but of course mine does not. I would think there would be a setting on the service menu. Anybody know if this can be adjusted? How do you get to the service menu? The overscan seems worse on the bottom.
