A:Answer Hi Edward, often you may want to change the size of the image on your screen. Your TV comes with several screen size options, each designed to work best with
specific types of video input.
• 16:9 : Sets the picture to 16:9 wide mode.
• Zoom1 : Magnifies the size of the picture on the screen.
• Zoom2 : Magnifies the size of the picture bigger than Zoom1.
• Wide Fit : Enlarges the aspect ratio of the picture to fit the entire screen.
• 4:3 : Sets the picture to 4:3 normal mode.
• Screen Fit : Use the function to see the full image without any cutoff when HDMI (720p/1080i/1080p), Component (1080i/1080p) or DTV (1080i) signals are input.
I hope this helps, ^Scott
