Some television programs are produced based on the assumption that older television sets 
may not display the outer edges of the broadcast picture area. Overscan effectively trims 
away these inactive, outer edges and enlarges the remaining portion of the image to fill the

Select from 1% to 10% of Overscan, as desired.
For HDTV, DVDs and other video sources, Overscan is generally not necessary or desirable.
