Technical Information

The optimum size and aspect can be chosen, and you can enjoy finer images. (p. 13)
Auto aspect: Auto aspect determines the best aspect ratio to use to fill 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 identification 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 fill the screen. This
process can take several minutes, depending on the darkness of the picture.

Note
The ratio varies depending on the programme, etc. If the ratio is greater than the standard "16:9", black bands
may appear at the top and bottom of the screen.
If the screen size looks unusual when a widescreen-recorded programme is played back on a VCR, adjust the
tracking of the VCR. (See the VCR manual.)
Aspect mode can be memorized for SD (Standard definition) and HD (High definition) signals separately.
To select the ratio manually: (Only "16:9" or "4:3" in PC mode)
