Image too large

Question

I have a Vizio L32 LCD and for the past couple of days I have noticed the image is too large. For instance, watching the news the news anchors heads are cut from the top or the side. Also the PIP images right next to their face also cut partly from the screen. I tried using the "wide" button, but that only makes the problem worst in some screens. Is there a setting I missed? Can this be fixed? This is quite annoying.
