An “overscan” is a concept that was introduced by television and computer monitor manufacturers to compensate for the fact that cathode ray tube displays couldn't reproduce images around the edges of their tubes. Although HDTV's don't have this problem, broadcasters still transmit images they expect to be cropped around the edges when they're displayed on TVs. You can view broadcast images on your set without an overscan, but may see items around the edge of your screen once you've changed your TV's settings.
Press the “MENU” button on your remote control. This will bring up the on-screen menu. Use the up and down arrows on your remote to navigate to “Picture” and press “ENTER” on your remote.
Select “Screen adjustment” from the “Picture” menu by highlighting it with the up and down arrows and then pressing “ENTER.” Select “Picture size” from the next set of options. Selecting “4:3” will remove overscan. However, Samsung does not recommend this option for long-term viewing because the blips and quirks around the edge of the picture will burn out the screen. If you select “Screen fit” instead, the full broadcast image will be altered to fit your screen if you're using “HDMI” or “Component” inputs.
Select “16:9” mode from the “Picture size” options to re-introduce overscan. Samsung recommends this setting for its HDTVs.
Press the “MENU” button on your remote control, navigate to “Picture” and press “ENTER."
Select “Screen adjustments” from the “Picture” menu and then select “Picture size.” Use the up and down arrows to move between options and then press the “ENTER” when the correct option is highlighted. Select “Zoom” from the “Picture size” options.
Go back to the “Screen adjustments” menu, move to “Position” and press the “ENTER.” Use the left, right, up and down buttons to shift the picture within the zoom window. Zoom crops off the edges of the picture, but you can shift the view so the left or right edge of the picture is shown. You can also choose between the top or the bottom edge. Press the “ENTER” key on the remote control when you have the best view.
Users of Samsung HDTV computer monitors will experience overscan in “Screen fit” mode. To avoid this, select a different screen display mode.
