Recently purchased a Samsung 40inch 1080p HDTV from best buy. I set it up and all that but I can't figure out how to set the image to full screen. I fiddled around with the image settings and there's no "full screen" option. There's
16:9 - The one it's set on
Zoom1 - (can't select it)
Zoom2 - (can't select it)
Wide fit - (can't get it the full width)
4:3 - Tried that nothing good happend
and Screen fit - (gives me the option to move the image but will not move if I press the arrows)

It is plugged into and HDMI cable to the box and TV

Just wondering if anyone knows how to set it to it's full screen mode.
