The ability of the projector to automatically synchronize to the horizontal
and vertical scan frequencies of an input signal.
The frequency range of the projector's video amplifier.

blanking time of the input signal must be equal to or greater than the
retrace time of the projector.
A horizontal curve in the center of the image, and/or a vertical curve across
an image.
Brightness in projection usually describes the amount of light emitted from
a surface such as a screen. Brightness is measured in lumens, foot-lamberts,
foot-candles, or lux.
The intensity of light is measured in candelas.
A 2-digit number with user-assigned source input information. This infor-
mation includes a physical input (switcher, slot), a setup memory (input
or recall), and a name or description. Assignments are made through the
Channel List.
A list of up to 99 channels (explained above) which may be created, edited,
or deleted by the user. The Channel List feature provides an alternative, and
sometimes easier, way to select sources and their setups.
The change in the tint of a white field across an image.
This term refers to the coloration (reddish, white, bluish, etc.) of a white
image. (It does not refer to the brightness of a white image.) The Kelvin (K)
temperature scale is used to measure color temperature.
The accuracy of color temperature at any location.
This term refers to the output of video tape players and some computers.
Synchronization, luminance, and color signals are combined on one
