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.

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.

Composite sync

Signal combining horizontal and vertical sync pulses.

DVI (Digital Visual Interface)

Display digital interface that also supports analog interfaces.

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 differ- ent modes: Standard, Cinema 1, Cinema 2 and Cinema 3.

Intelligent compression and expansion

High quality resizing of lower and higher resolu- tion images to fit the projector’s native resolution.

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.

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 dis- play mode to enhance the input image. You can se- lect from four different modes: STRETCH, SIDE BAR, SMART STRETCH and CINEMA ZOOM.

RS-232C

Function to control the projector from the com- puter by using the RS-232C ports on the projec- tor and computer.

Stretch

Projects the 16:9 image or the squeezed image (*1) fully in a 16:9 screen.

*1...16:9 image that is squeezed horizontally into 4:3 image
