Facilità d'uso
If the setting does not match the input signal, the dark screen is saturated and may not display properly or the dark screen looks milky-white. VIDEO IN Port A COMPOSITE IN Port is a general video input port (yellow). Both chrominance and luminance are transmitted on the same 75-ohm cable. Color Standard A pre-determined default color standard determined by the broadcasting standard of the corresponding country or area. Color Temperature Color temperature is a simplified way to characterize the spectral properties of a light source. A low color temperature implies a warmer (more yellow/red) light while a high color temperature implies a colder (more blue) light. Vertical Keystone This correction function is used when vertical distortion of the projected picture occurs. Vertical distortion refers to the distortion of the projected picture when the beam from the projector is not perpendicular to the screen. You can view pictures more comfortably by correcting the distortion using the Vertical Keystone function. Analog Broadcast An existing broadcasting signal transmitted by a broadcasting station in accordance with the NTSC standard. Overscan Overscan cuts the edge of the picture when there is unnecessary information, images or noise at the edge of the picture. For extremely poor video signals, some unnecessary video signals may be displayed on the screen. ^ External Input External Input is connecting video devices such as a VCR, camcorder, DTV receiver, DVD, etc. to the projector as a video source. ^ Satellite Broadcast Satellite Broadcast broadcasts programs via satellite so that the program can be viewed in all area in a high visual and sound quality. Approximately 100 channels including public broadcast channels are provided. To view satellite broadcasts, you have to install an additional receiver. Cable Broadcast Cable Broadcast broadcasts programs via cable instead of radio waves. To view cable broadcasts, you have to subscribe to your local cable broadcast service provider and install an additional receiver. ^ Projected Picture A picture projected by the projector onto the screen. Resolution Pixels are a number of horizontal / vertical dots making up the TV screen. The resolution represents the number of pixels on a screen. Since, the more pixels there are, the more information is displayed, select a higher resolution when you wish to view multiple tasks simultaneously. For example, if the resolution is 800 * 600, this means the width of the screen consists of 800 dots (Horizontal Resolution) and the height of the screen consists of 600 lines (Vertical Resolution). ANSI Abbreviations of the American National Standards Institute & ANSI Lumen Unit of brightness as defined by the American National Standards Institute. This value is determined as follows: project light onto a 40-inch screen, divide the screen into 9 rectangles and measure the average brightness of each of the rectangles. Since the brightness at the center is generally different from that of the edges, ANSI Lumen provides a more precise measure of the projector brightness than LUX. AV Receiver An AV Receiver provides a number of input and output interfaces for audio and video so as to enable the user to connect and use various input and output devices. Backwards Compatible Backwards compatibility for previous computer models. The SVGA (800*600) projector provides backwards compatibility for SVGA and VGA (640*480) computers. Compression Mode A mode that displays video in a zoomed out format. ^ Contrast Ratio The ratio of the brightest and dimmest points that can be displayed on the screen. Convergence The alignment of the Red, Green and Blue video signals on the projected picture on the screen. Display Size The Display Size is determined by the diagonal length of the LCD panel. DVD (Digital Versatile Disc) Digital media developed to provide the advantages of CD and LD. DVD provides high quality video and audio. DLP (Digital Light Processing) DLP is a digital display technology using a DMD panel developed by TI (Texas Instruments) of the United States. & DLP HD2, DC2, DC3 This is a grade of DMD panel. DMD (Digital Micromirror Device) A DMD panel is an implementation of DLP technology. It consists of microscopic mirrors where each mirror represents a pixel. EGA Enhanced Graphics Array. EGA provides enhanced graphics quality in IBM PC, XT and AT as a CGA card. (640x350 pixels for all modes) & Hz (kHz, MHz) Hertz (Kilohertz, Megahertz). Frequency per second. (Kilo: 1,000, Mega: 1 million) Hz is used to represent the frequency of electric signals. & NTSC National Television Standards Committee. A TV and video signal transmission standard developed in North America in 1953. 525lines / 60 Hz PAL Phase Alternate Line. A method to transmit and receive color line by line. PAL is widely used in Western European countries. 625lines / 50 Hz S> SECAM Sequential Couleur Avec Memorie. A method develope...
