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
Optimizes projected computer images by automatically adjusting certain characteristics.
Background
Initial setting image projected when no signal is being input.
Border
Displays the 4:3 image as the biggest size (768 576) that can be displayed on the WIDE mode screen (1024 576).
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 temperature to suit the type of image input to the projector. Decrease the color 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 shift
Shifts image up or down easily by ∂/ƒ buttons when RESIZE mode of input image is BORDER, STRETCH or SMART STRETCH of COMPUTER (except for SXGA and UXGA), VIDEO and DTV inputs.
DNR (Digital Noise Reduction)
Provides high quality images with minimal dot crawl and cross color noise.
Dot by dot
Mode that projects images in their native resolution.
DVI
Digital Visual Interface that supports both digital and analog displays.
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 CUSTOM.
GyroRemote
Remote control device with a
Intelligent compression and expansion
High quality resizing of lower and higher resolution images to fit the projector’s native resolution.
Intelligent digital keystone correction
Function to digitally correct a distorted image when the projector is set up at an angle, smooths out jaggies on keystone images and compresses the image not only horizontally but vertically keeping the 4:3 aspect ratio, and at the same time, calculates the aspect ratio automatically adjusting to the lens shift width.
Keylock level
Mode that can lock the operation of projector buttons to prevent mischief.
Lens shift
The lens can be easily raised and lowered to minimize or eliminate “Keystone” type effect.
Magnification (Enlarge)
Digitally zooms in on a portion of an image.
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 presentations.
Presentation tools
Helpful tools used to emphasize keypoints throughout a presentation.
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 display mode to enhance the input image. You can select six different modes: NORMAL, FULL, DOT BY DOT, BORDER, STRETCH and SMART STRETCH.
RS-232C
Function to control the projector from the computer by using the
Set Inputs
Function to limit inputs. For example, when setting Input 2 to “OFF”, the input is switchable only between Input 1 and Input 3, skipping Input 2.
Smart Stretch
Mode that stretches the right and left sides of the 4:3 image horizontally while maintaining the aspect ratio around the center of the image to display it on the WIDE screen.
Stack Setting
Prevents trouble with adjustment and operation when stack projecting. When setting two projectors, one to master and the other to slave, the slave follows the master’s operation.
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 color signal pin.
