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 output.
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 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.
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 16 : 9 aspect ratio.
DVI (Digital Visual Interface)
Display digital interface that also supports analog interfaces.
-68
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 from four different modes: Standard, Cinema 1, Cinema 2 and Cinema 3.
Intelligent compression and expansion
High quality resizing of lower and higher resolution images to fit the projector’s native resolution.
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.
Resize
Allows you to modify or customize the picture display mode to enhance the input image. You can select from four different modes: SIDE BAR, SMART STRETCH, CINEMA ZOOM and
STRETCH.
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.
