VistaPro 2000 User's Manual
The smallest discernible element of data from a computer-generated image.
The phase of the pixel sampling clock relative to incoming data.
The frequency of the pixel sampling clock, indicated by the number of pixels per
line.
The projector is at presentation level when an image from a source is displayed
without the presence of a slidebar, menu, pull-down list, or error message. For
example, if a help page is displayed, the projector is not at presentation level.
The distance between the projector's front feet and the screen. Also called
"Throw Distance”.
The type of code format utilized by IR keypad(s). The default from manufacture
is Protocol A. By using two different protocols, two projectors may be used side
by side while being controlled independently by their remote IR keypads.
A selectable menu item that unfolds into a list of options pertaining to a given
parameter.
A translucent panel for screen projection. Incident light travels through the
incident surface of a rear screen and forms an image on the other surface.
The maximum number of alternate white and black horizontal lines that can be
distinguished on a screen when a photographic target is placed between the lens
and a light source, and illuminated by that light source.
The maximum number of pixels that the projector can display horizontally and
vertically across an image.
The minimum time required for a CRT projector to move the position of the
scanning spot from the right edge to the left edge.
The time required by the video amplifier of the projector to increase its output
from 10% to 90% of the maximum value.
The video output (analog or digital) of most computers. Analog RGB video can
have 3, 4, or 5 wires — one each for red, green, and blue, and either none, one or
two for sync. For three-wire RGB, the green wire usually provides sync. (See
TTL Video).
An asynchronous data transmission standard recommended by the Electronics
Industries Association (EIA). Also called serial communication.
The output from certain video tape players and video equipment. S-Video
separates sync and luminance from color information, typically producing a
higher quality display than composite video.
The horizontal or vertical frequency at which images are generated.
One horizontal line on the display.
