■ Terminology
This section provides simple explanations for the terminology used within the manual, items
for which explanations are not available, and other complex processes.
A/V Mute Temporarily erases the image and sound at the same time. The sound and image
can be muted by pressing the [A/V Mute] button on the projector. Press the [A/V
Mute] button once again or adjust the volume or display the menu to cancel the
mute mode.
DVI-D port The input port that conforms to the DVI digital video ratings (Digital Visual Inter-
face: Ratings to govern how video signals are digitally transmitted). Synchroniza-
tion and tracking misalignments will not occur during transmission.
D output port The output port for digital tuners that support the new digital broadcasts within
Japan.
Remote port Cannot be used with this projector.
SVGA IBM PC/AT compatible (DOS/V equipment) signals with 800 horizontal pixels
and 600 vertical pixels.
SXGA IBM PC/AT compatible (DOS/V equipment) signals with 1,280 horizontal pixels
and 1,024 vertical pixels.
Sync(synchronization) Outputs computer signals at a pre-determined frequency. The image will not be
projected clearly unless this frequency is aligned with the frequency of the projec-
tor. Aligning the signal phasing is known as synchronization. Projected images
will be subject to distrubance, blurring and horizontal noise if not synchronized.
VGA IBM PC/AT compatible (DOS/V equipment) signals with 640 horizontal pixels
and 480 vertical pixels.
XGA IBM PC/AT compatible (DOS/V equipment) signals with 1,024 horizontal pixels
and 768 vertical pixels.
USB An abbreviation for Universal Serial Bus. This is an interface for connecting com-
paritively low frequency equipment to the computer.
UXGA IBM PC/AT compatible (DOS/V equipment) signals with 1,600 horizontal pixels
and 1,200 vertical pixels.
Color temperature The temperature of the subject that emits light. A blue hue is attained when the
color temperature is high, and a red hue is attained when the color temperature is
low.
Color differential signal Video equipment transmits signals through three cables as Red-Bright (R-Y),
Bright (Y) and Blue-Bright (B-Y). This enables the composite signals (the red, green
and blue signals and their brightness signals are transmitted along one cable) to be
projected more clearly.
Operating system The software necessary to operate the computer.
Cool-down A lamp cooling procedure continues to operate even after the power supply has
been switched off and the lamp extinguished. The cooling fan will begin to operate
when the lamp is entinguished, and button operations will not longer be possible.
This period is known as the cooling down period. The amount of time required for
the cooling down procedure will differ in accordance with the surrounding tem-
perature.
