Runco PL-61CX - Manual (Page 32)

The example on the previous page shows what would happen on a widescreen display if a small 4:3 image were used
more often than widescreen images.
To minimize this problem, the PL-61cx can 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, min-
imizing 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.
To use side bar level, it will be necessary to 'unblank' the left and right sides of the image. Please follow this proce-
dure to set side bar level:
· Ensure an active source is displayed on the screen or display.
· Select the standard (4:3) aspect ratio.
· Access the INSTALLATION menu, highlight BLANKING and press ENTER.
· Highlight LEFT with the up or down arrow buttons, then press and hold the left arrow button. You will begin to see
the sidebar slowly appear on the left side.
NOTE: If you do not see the sidebar begin to appear, increase the Side Bar Level and retry. Continue holding
down the left arrow button until the left sidebar fills the left side of the screen.
· When the left side is fully unblanked, perform the same procedure for the right side.
· Once both sides are fully unblanked, you can set the level of the sidebars. 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.

Invert
If an image has been accidentally 'burned' into the display, the INVERT function will invert the colors so as to try to
neutralize any 'burn' in the image. For example, white areas will become black, black areas will become white, etc.
In order for this to be effective, you MUST have the exact same image on-screen that was burned into the image, and
it must be in the exact same place (ensure it was not electronically shifted). The amount of time the invert feature
should be left on depends on the severity of the burn. Runco recommends that if you know how long the image was
left on, leave the image 'inverted' for 50% of that time and re-evaluate the burn. Otherwise, leave it on for increments
of an hour or two and re-evaluate the burn each time.
