left and right of the image to preserve the original aspect ratio of the source. Note: Use this mode for
only 15% of your total viewing time to prevent uneven aging of the phosphors. Phosphors in the lighted
area of the picture will age more rapidly than the gray areas.
Use this aspect mode to display conventional (4:3) sources by linearly increasing image expansion from
the center towards the edges of the display area in order to fill it.
Use these aspect modes to zoom in on conventional (4:3) sources.
Use this aspect mode to display 16:9 sources like HDTV and DVD's preserving the original 16:9 aspect
ratio.
