Glossary
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
Optimises projected computer images by automatically adjusting certain characteristics.
Background
Initial setting image projected when no signal is being input.
Cinema zoom
Mode that projects the 16:9 image which uses the centre of the image signal on the full-screen.
Clock
Clock adjustment is used to adjust vertical noise when clock level is incorrect.
CLR Temp (Colour temperature)
Function that can be used to adjust the colour temperature to suit the type of image input to the projector. Decrease the colour temperature to create warmer,
reddish images for natural flesh tones, or increase to create cooler, bluish images for a brighter picture.
Composite sync
Signal combining horizontal and vertical sync pulses.
Digital keystone correction
Function to digitally correct a distorted image when the projector is set up at an angle, smoothes out jaggies on keystone images and compresses the image
not only horizontally but vertically keeping the 4 : 3 aspect ratio.
Digital shift
Shifts image up or down easily by
/
buttons when RESIZE mode of input image is SMART STRETCH, CINEMA ZOOM, or DOT BY DOT of COMPUTER,
VIDEO and DTV inputs.
Dot by dot
Mode that projects images in their native resolution.
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, GAMMA 1, GAMMA 2 and CUSTOM.
Intelligent compression and expansion
High quality resizing of lower and higher resolution images to fit the projector’s native resolution.
Lens shift
The lens can be easily raised and lowered to minimise or eliminate “Keystone” type effect.
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.
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 customise the picture display mode to enhance the input image. You can select six different modes: SIDE BAR, SMART STRETCH,
CINEMA ZOOM, STRETCH, NORMAL, and DOT BY DOT.
RS-232C
Function to control the projector from the computer by using the RS-232C ports on the projector and computer.
Side bar
Mode that projects the normal 4:3 image at the 4:3 area for the centre of the screen.
Smart Stretch
Mode that stretches the right and left sides of the 4:3 image horizontally while maintaining the aspect ratio around the centre of the image to display it on the WIDE
screen.
Status function
Displays the settings of each adjustment item.
Stretch
Mode that stretches the 4:3 image horizontally to display it on the WIDE screen.
Sync on green
Video signal mode of a computer which overlaps horizontal and vertical sync signal to green colour signal pin.
3D DNR (3D Digital Noise Reduction)
Provides high quality images with minimal background.
