Overscan: Image Overscan pushes the outside edge of the active picture area of the 
video signal out beyond the edge of the display area. 
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 display area.
