Glossary
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.
Optimizes projected computer images by automatically adjusting certain characteristics.
Initial setting image projected when no signal is being input.
Displays the 4:3 image as the biggest size (768
ן576) that can be displayed on the WIDE mode screen (1024ן576).
Clock adjustment is used to adjust vertical noise when clock level is incorrect.
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.
Signal combining horizontal and vertical sync pulses.
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.
Mode that projects images in their native resolution.
Digital Visual Interface that supports both digital and analog displays.
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.
Intelligent 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, and at the same time, calculates the aspect ratio automatically adjusting to the lens shift width.
Mode that can lock the operation of projector buttons to prevent mischief.
Mode that enables you to use two lamps in different combinations. You can select four different modes : Both Lamps (use two lamps simultaneously), Lamp 1 only
(use only lamp 1), Lamp 2 only (use only lamp 2 ) and Equal Use (use lamp 1 and lamp 2 alternatingly).
The lens can be easily raised and lowered to minimize or eliminate “Keystone” type effect.
Digitally zooms in on a portion of an image.
The expansion board (sold separately) enables you to respond to the image signal for business-use and RS-422 control.
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.
Allows you to add video images onto a data screen image, providing you with even more effective presentations.
Helpful tools used to emphasize keypoints throughout a presentation.
The progressive display projects a smoother video image. You can select three different modes : 2D Progressive, 3D Progressive and Film Mode.
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.
Function to control the projector from the computer by using the RS-232C ports on the projector and computer.
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.
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.
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.
Displays the settings of each adjustment item.
Mode that stretches the 4:3 image horizontally to display it on the WIDE screen.
Video signal mode of a computer which overlaps horizontal and vertical sync signal to green color signal pin.
3D DNR (3D Digital Noise Reduction)
Provides high quality images with minimal dot crawl and cross color noise.
