To minimize this problem, the PL-50HDXcan provide SIDE BARS, which will put grey bars up on either side of
a small 4:3 image (see 'side bar area' in the drawing above). This illuminates the otherwise unused portion of
the display, minimizing a potential 4:3 burn.
SIDE BAR LEVEL is the amount of illumination in the side bars. The goal is not to make them so bright that
they are much brighter than the 4:3 image itself (which could cause a reverse 4:3 burn), but not too dim where
they cannot be effective. While there is not a recommended level, Runco recommends keeping the side bar
level at a moderate level, approximately the same as the average light used on the 4:3 portion of the image.
IMPORTANT: Runco is not responsible for image burns on any display.
Please exercise caution when using a 4:3 image on a 16:9 screen.
Please follow this procedure to set side bar level:
·Ensure an active source is displayed on the screen or display.
·Select the standard (4:3) aspect ratio.
·Highlight SIDE BAR LEVEL on the INSTALLATION menu and press ENTER. Use the up arrow button to
increase the illumination of the side bars, or the down arrow to decrease their illumination.
NOTE: It is recommended that an active image be displayed on-screen, and the level of the sidebars be
set to match the average amount of illumination on the 4:3 portion of the image.

Some displays, especially phosphor-based displays such as Plasma (flat panel) displays, can be 'burned' by
still-images or otherwise not using the full display or raster.
Besides still images, using a 4:3 image on a widescreen display could cause a '4:3 burn' (see below):
