Gamma Mode
Gamma Mode compensates the video signal produced for analog display devices such as a CRT (Cathode Ray Tube)
so that the video signal can be clearly displayed on a digital display device.
Black Level
Black Level sets the light level of the darkest portion of the video signal to match that of the display's black level
capability so that users can clearly view dark visuals. 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.
