Use this aspect mode to display conventional (4:3) images. Side panels (gray areas) are placed to the
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 expanding the outer edges of the image
to fill the 16:9 screen. The center of the image remains unaltered.

ratio.
