Glossary
Advanced intelligent compression
High quality resizing of lower and higher resolu-
tion images to fit the projector’s native resolution.
Anti-theft
In case the projector is stolen, this function dis-
ables projection of images if the correct keycode
is not entered.
Aspect Ratio
Width and height ratio of an image. The normal
aspect ratio of a computer and video image is 4:3.
There are also wide images with an aspect ratio
of 16:9 and 21:9.
Auto Sync
Optimizes projected computer images by auto-
matically adjusting certain characteristics.
Background
Initial setting image projected when no signal is
being output.
Border
Projects a 4:3 image fully within a 16:9 screen by
keeping the aspect ratio at 4:3.
Clock
Clock adjustment is used to adjust vertical noise
when clock level is incorrect.
CLR Temp (Color temperature)
Function that can be used to adjust the color tem-
perature to suit the type of image input to the pro-
jector. Decrease the color temperature to create
warmer, reddish images for natural flesh tones,
or increase to create cooler, bluish images for a
brighter picture.
Digital Shift
Shifts image up or down easily by , but-
tons when RESIZE mode of input image is BOR-
DER, STRETCH or SMART STRETCH of the
video or the DTV signals.
Dot by dot
Mode that projects images in their native resolution.
DVI (Digital Visual Interface)
Display digital interface that also supports Ana-
log interfaces.
Freeze
Temporarily freezes a moving image.
GAMMA
Image quality enhancement function that offers a
richer image by brightening the darker portions of
the image without altering the brightness of the
brighter portions. You can select four different
modes: STANDARD, PRESENTATION, CINEMA
and GAME.
Keylock Level
Mode that can lock the operation of projector but-
tons to prevent mischief.
Keystone correction
Function to digitally correct a distorted image when
the projector is set up at an angle, smoothens out
jaggies on keystone images and compresses the
image not only horizontally but vertically keeping
the 4:3 aspect ratio.
Password
A password is set so that changes cannot be made
in the settings of the “Options (2)” menu.
Phase
Phase shift is a timing shift between isomorphic
signals with the same resolution. When phase
level is incorrect, the projected image typically
displays horizontal flicker.
Picture in Picture
Allows you to add video images onto a data screen
image, providing you with even more effective pre-
sentations.
Progressive Mode
The progressive display projects a smoother video
image. You can select three different modes: 2D
Progressive, 3D Progressive and Film Mode.
RESIZE
Allows you to modify or customize the picture dis-
play mode to enhance the input image. You can
select six different modes: NORMAL, FULL, DOT
BY DOT, BORDER, STRETCH and SMART
STRETCH.
Smart Stretch
Projects the image fully in a 16:9 screen by en-
larging only the surrounding areas while keeping
the aspect ratio in the middle part of the image at
4:3.
sRGB
An international standard of color reproduction
regulated by the IEC (Inter national
Electrotechnical Commission). As the fixed color
area has been decided by the IEC, the color
changes according to DLP features, so that the
images are displayed in a natural tint based on
an original image, when switching to the “sRGB”
mode.
Startup Image
The image displayed when the projector is turned
on.
Status function
Displays the settings of each adjustment item.
Stretch
Mode that stretches the 4:3 image horizontally to
display it fully on a 16:9 screen.
