'
A menu item that indicates whether an option is currently in effect (checked) or not
(unchecked).
'
A change in the tint of a white field across an image.
'
The coloration (reddish, white, bluish, greenish, etc.) of white in an image, measured
using the Kelvin (degrees K) temperature scale. Higher temperatures output more
light.
'
See YCbCr or YPbPr.
'
The output of video tape players and some computers, characterized by
synchronization, luminance and color signals combined on one output cable.
'
The degree of difference between the lightest and darkest areas of the image.
'
The alignment of the red, green, and blue elements of a projected image.
'
A projection screen which is slightly concave for improved screen gain. Curved
screens usually have screen gains, which are greater than 1 but viewing angles much
less than 180
'
DDI A "direct digital interface" signal can be supplied to the projector via an optional
digital input module installed in
259M signal using a Serial Digital Input Module or input an SMPTE-272M signal
from a Digital HDTV Serial Input Module.

PAL-N, PAL-M, or SECAM to RGB video.
'
Detail The sharpness of a display from a video source.
'
A type of rear-projection screen which spreads the light striking it. Screen gain is less
than 1 but audience viewing angles are increased.
'
An adjustment that affects the display of an image. Such display settings include
contrast, brightness, tint, blanking, size, offsets, and others.
'
A very rapid variation in image brightness caused by a frame rate that is too slow.
(See Interlace) See also Lamp Flicker.
'
The frequency at which complete images are generated. For non-interlaced signals,
the frame rate is identical to the vertical frequency. For interlaced signals, the frame
rate (also known as field rate) is one half of vertical frequency.
'
The intensity of visible light per square foot.
'
The luminance (brightness) which results from one foot-candle of illumination falling
on a perfectly diffuse surface.
'
The ability of a screen to direct incident light to an audience. A flat matte white wall
has a gain of approximately 1. Screens with gain less than 1 attenuate incident light;
