ASPECT

This setting is only for an S-VIDEO/ VIDEO signal and a YPBPR signal in 525i (480i), 525p (480p) and 625i format.

AUTO

(S-VIDEO only)

When an S1 video signal is input to the S-VIDEO terminal, the aspect ratio is changed automatically to project a 16:9 picture.

4:3

The input signal is projected without change.

16:9

The picture is compressed to a ratio of 16:9 and projected.

When a squeezed signal is being input. (The projected image is contracted horizontally)

[

S4:3

The size of the input signal is compressed to 75% and projected. (This is useful for projecting a picture with a 4:3 aspect ratio onto a 16:9 screen.)

S1 video signals

BS1 video signals are a type of video signal with an aspect ratio of 16:9 which include a detector signal. This detector signal is output by some sources such as wide-vision video decks. If the AUTO setting above is selected, this projector will recognise the detector signal and automatically switch the aspect ratio to 16:9 in order to project the picture.

NOTE:

BThis projector is equipped with an aspect ratio selection function. However, if a mode which does not match the aspect ratio of the input signal is selected, it may affect the quality of viewing of the original picture. Keep this in mind when selecting the aspect ratio.

BIf using this projector in places such as cafes or hotels with the aim of displaying programs for viewing for a commercial purpose or for public presentation, note that if the aspect ratio (16:9) selection function is used to change the aspect ratio of the screen picture, you may be infringing the rights of the original copyright owner for that program under copyright protection laws.

BIf a normal (4:3) picture which was not originally intended for wide- screen viewing is projected onto a wide screen, distortion may occur around the edges of the picture so that part of the picture is no longer visible. Such programs should be viewed in 4:3 mode to give proper consideration to the aims and intentions of the original program’s creator.

RESIZING

This should normally be set to “ON”. (This setting is only for signals which have lower resolutions than the LCD panels. Refer to page 56 for details.)

ON

The pixel resolution of the input signal is converted to the same resolution as the LCD panels before being projected. For signals with lower resolutions, gaps in the pixels are automatically interpolated into the picture before it is projected. This may sometimes cause problems with the quality of the picture.

OFF

The picture signal is projected at its original resolution, with no pixel conversion. The projected picture will be smaller than normal, so adjust the zoom setting or move the projector forwards or backwards to adjust the picture size if necessary. If set to “OFF”, some features, such as D.ZOOM (digital zoom), keystone distortion correction or INDEX WINDOW will not function.
