Glossary Aspect (P58, P73, P131) The aspect ratio is the ratio of the horizontal (longer) dimension to the vertical (shorter) dimension of a screen. It is expressed as "longer dimension : shorter dimension." The following aspect ratio is normally used: [4:3] The aspect ratio widely accepted in the standard screen resolution, for example the traditional television screen and VGA (640 x 480) and XGA (1024 x 768) in computer. The aspect ratio for this projector is 4:3. [5:4] This aspect ratio is used if you select the resolution such as SXGA (1280 x 1024) in computer. The shorter dimension in [5:4] is a little longer than that in [4:3]. An image is displayed with proper screen aspect if you select [Auto] or [True size] for [Screen aspect]; however, the margins are displayed on both sides of the screen. [16:9] The aspect ratio for the high definition or wide-screen. WXGA (1280 x 768 and 1360 x 768) is used as the aspect ratio close to 16:9 for the wide screen monitor in computer. An image with aspect ratio of 16:9 is properly displayed if you select [Auto] for [Aspect]; however, the margins are displayed at the top and bottom of the screen. For the aspect ratio for movie screens, "vista vision size" and "cinema scope size", etc. are used. "Vista vision size" The aspect ratio close to 16:9. Select [Auto] or [16:9] for [Aspect]. The back belts are added at the top and bottom of the image. "Cinema scope size" The landscape-oriented aspect ratio of 8:3. Select [Auto] or [16:9] for [Aspect]. The back belts are added at the top and bottom of the image. Component (P27, P40, P88) 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 betterquality image as compared with the composite signal system. Connect the component video terminal on the AV equipment and the ANALOG PC-2/COMPONENT IN terminal on this projector with a component cable. Select [COMPONENT] at projection. Tracking (P50, P76) To reproduce an image from an analog image signal, the process to accumulate image information at the appropriate timing with reference to the synchronization signal within the image signal is required. This process is called the tracking. This projector can display an image properly by automatically adjust the tracking with the auto PC adjustment function even if there is a small difference in the synchronization signal from an analog imaging device. Resolution (P49) The number of dots (horizontal dots x vertical dots) that can be displayed on a computer is called "resolution of display". Resolution indicates the size of the display area (amount of information). Resolution Number of dots Horizontal Vertical VGA 640 480 SVGA 800 600 XGA 1024 768 SXGA 1280 1024 SXGA+ 1400 1050 UXGA 1600 1200 136
