Analog RGB

A signal system used to send information about R (red), G (green), and B (blue) with analog values. It is a typical system for connecting a color monitor to a computer. Connect the analog RGB output terminal of the computer and the DVI-I/RGB IN-1 terminal or RBG-2/ COMPONENT IN/RGB OUT terminal of this projector with a monitor cable. When the RGB IN-1 terminal is used, select “ANALOG RGB-1” by pressing the [COMPUTER-1] button. When the RGB IN-2 terminal is used, select “ANALOG RGB-2” by pressing the [COMPUTER-2] button.

Digital RGB

A signal system used to send information about individual display dots with digital values. This system is free from deterioration of image quality because of no analog conversion. Connect the DVI output terminal of the computer and the DVI-I/RGB IN-1 terminal of this projector with a connection cable and select “DIGITAL RGB” by pressing the [COMPUTER- 1] button.

Video

An output terminal widely used for AV equipment. It is also called a composite output terminal (pin terminal or RCA terminal). For more details, refer to “Composite”.

S-video

A signal system (YC separation signal) used to send a brightness signal (Y) and color signal

(C)separately. Connect the S-video terminal of AV equipment and the S-VIDEO IN terminal of this projector with an S-video cable and select “S-VIDEO” by pressing the [VIDEO/S] button.

Component

A signal system used to send a color signal (C) with it divided into a B-Y color difference signal and an R-Y color difference signal. This system can project a better-quality image as compared with the composite signal system. Connect the video terminal of AV equipment and the RGB-2/COMPONENT IN/RGB OUT terminal with a component cable and select “COMPONENT” by pressing the [COMPUTER-2] button.

Composite

A video signal system used to send a brightness signal (Y) and a color signal (C) together. Connect the composite output terminal (RCA) of AV equipment and the VIDEO IN terminal of this projector with a video cable and select “VIDEO” by pressing the [VIDEO/S] button.

sRGB

An international standard of color representation (color space) which is applied to digital cameras, displays and others. If you select sRGB, the projector can project the best-quality image conforming to the sRGB Standard.
