Squeeze mode

In this mode, wide-screen images in 16:9 mode are compressed in the horizontal direction so that they are stored on the

 

 

 

 

recording medium as 4:3 images.

 

 

 

When these images are played back by the projector in squeeze mode, they are restored to their original 16:9 format.

 

 

 

 

 

 

sRGB

An international standard for colour intervals that was formulated so that colours which are reproduced by video equipment

 

 

 

 

can be handled easily by computer operating systems (OS) and the Internet. If the connected source has a sRGB mode, set

 

 

 

both the projector and the connected signal source to sRGB.

 

 

 

 

 

 

 

SVGA

A type of video signal with a resolution of 800 (horizontal) 600 (vertical) dots which is used by IBM PC/AT-compatible

 

 

 

computers.

 

 

 

 

 

 

S-Video

A video signal which has the luminance component and colour component separated in order to provide better image quality.

 

 

 

 

It refers to images which consist of two independent signals: Y (luminance signal), and C (colour signal).

 

 

 

 

 

 

 

SXGA

A type of video signal with a resolution of 1280 (horizontal) 1024 (vertical) dots which is used by IBM PC/AT-compatible

 

 

 

computers.

 

 

 

 

 

 

Sync (synchronisation)

The signals output from computers and RGB video equipment have a specific frequency. If the projector frequency does not

 

 

 

 

match this frequency, the resulting images will not be of a good quality. The process of matching the phases of these signals

 

 

 

(the relative position of the crests and troughs in the signal) is called “synchronisation.” If the signals are not synchronized,

 

 

 

problems such as flickering, blurriness and horizontal interference can occur.

 

 

 

 

 

 

Tracking

The signals output from computers and RGB video equipment have a specific frequency. If the projector frequency does not

 

 

 

 

match this frequency, the resulting images will not be of a good quality. The process of matching the frequency of these

 

 

 

signals (the number of crests in the signal) is called "tracking". If tracking is not carried out correctly, wide vertical stripes will

 

 

 

appear in the projected images.

 

 

 

 

 

 

USB

An abbreviation for Universal Serial Bus. USB is an interface for connecting personal computers to peripheral devices which

 

 

 

 

only support relatively low data transmission speeds.

 

 

 

 

 

 

 

VGA

A type of video signal with a resolution of 640 (horizontal) 480 (vertical) dots which is used by IBM PC/AT-compatible

 

 

 

computers.

 

 

 

 

 

 

 

XGA

A type of video signal with a resolution of 1024 (horizontal) 768 (vertical) dots which is used by IBM PC/AT-compatible

 

 

 

computers.
