Component (P25, 62, 90) 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 component video terminal on the AV equipment and the Input Terminal-2 on this projector with a component cable. Select [COMPONENT] at projection. Composite (P25, 64) A video signal system used to send a brightness signal (Y) and a color signal (C) together. Connect the composite output (RCA) terminal on the AV equipment and the VIDEO IN terminal on this projector with a video cable. Select [VIDEO] at projection. Digital PC (P25, 35) A signal system used to send digital information of individual display dots. This system is free from deterioration of image quality because of no analog conversion. Connect the DVI output terminal on the computer and Input Terminal-1 on this projector with a DVI connection cable. Select [DIGITAL PC] at projection. DVI (P35, 46, 63, 68) A digital video signal connection interface for a computer and AV equipment. This interface allows digital data to be transmitted without converting to analog data, assuring high image quality with no signal degradation. The DVI-I (integrated) connector can be used to transmit both an analog video signal and digital video signal. Gain (P103) A parameter that adjusts the reproduction range of a brightness signal from black to white within the image signal to naturally reproduce it on the screen. The reproducibility of the bright tone is mainly changed. Since you can adjust the gain for each RGB color in this projector, you can also adjust colors. The gain is normally adjusted with the offset. Gamma Correction (P102, 104) A tone adjustment system used during projection of image data. The gamma correction function works effectively when portions of an image are obscure because they are too light or dark. This projector supports manual gamma correction and dynamic gamma correction which performs the gamma correction automatically. HDCP (P63, 68) An abbreviation of High-bandwidth Digital Content Protection which is an encryption technology for copy protection of digital image signals. In this projector, you can project digital contents copy-protected with the HDCP technology. To project the contents, connect the Input Terminal-1 on the projector and an HDMI terminal or DVI terminal on an AV equipment with a dedicated cable, and then select [DIGITAL VIDEO] from the [INPUT] menu. HDMI (P63, 68) A digital video signal connection interface for an AV equipment. Its terminal is more compact than the DVI terminal. It allows to transmit video and audio signals simultaneously.
