Panasonic TH-42PX45EH operating instructions Aspect Ratio, Etc

Aspect Ratio

The optimum size and aspect can be chosen, and you can enjoy fi ner images. (p. 11)

ŶAuto aspect: Auto aspect determines the best aspect ratio to use to fi ll your screen. It does this using a four step process to determine if the picture being viewed is a widescreen picture.

If Auto aspect detects a widescreen signal it switches into the appropriate 16:9 or 14:9 widescreen mode. If Auto aspect does not detect a widescreen signal then this advanced TV enhances the picture for optimum viewing pleasure.

The text shown on the screen indicates how Auto aspect determined which ratio to use:

"WIDE" appears in the top left of the screen if a widescreen identifi cation signal (WSS) is found or a signal found through a SCART terminal. Auto aspect switches to the appropriate 16:9 or 14:9 widescreen ratio. This function will also work in any aspect mode. "Auto aspect" appears in the top left of the screen if black stripes above and below the picture are detected. Auto aspect chooses the best ratio and expands the picture to fi ll the screen. This process can take several minutes, depending on the darkness of the picture.
