Glossary

Advanced intelligent compression

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

Anti-theft

If the “Keycode” set in the projector is not cor- rectly entered, the projector will not operate even if signals are entered.

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.

Border

Projects a 4:3 image fully within a 16:9 screen by keeping the aspect ratio at 4:3.

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.

C.M.S. (Color Management System)

Function allows you individually adjust the display characteristics of six colors (R: Red, Y: Yellow, G: Green, C: Cyan, B: Blue, M: Magenta)

Digital Shift Setting

Shifts image up or down easily by ', " buttons when RESIZE mode of input image is BORDER, STRETCH or SMART STRETCH of the video or the DTV signals.

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, PRESENTATION, CINEMA and CUSTOM.

Keylock Level

Mode that can lock the operation of projector but- tons to prevent mischief.

Keystone correction

Function to digitally correct a distorted image when the projector is set up at an angle, smooth- ens out jaggies on keystone images and com- presses the image not only horizontally but verti- cally keeping the 4:3 aspect ratio.

Notevision Lock Down

A new ceiling mounting mechanism that is ef- fective in anti-theft and realizing improved in- stallation strength.

Password

A password is set so that changes cannot be made in the settings of the “Options (2)” menu.

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 pre- sentations.

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 dis- play mode to enhance the input image. You can select six different modes: NORMAL, FULL, DOT BY DOT, BORDER, STRETCH and SMART STRETCH.

Smart Stretch

Projects the image fully in a 16:9 screen by en- larging only the surrounding areas while keeping the aspect ratio in the middle part of the image at 4:3.

sRGB

An international standard of color reproduction regulated by the IEC (International Electrotechnical Commission). As the fixed color area has been decided by the IEC, the color changes according to LCD features, so that the images are displayed in a natural tint based on an original image, when switching to the “sRGB” mode.

Stretch

Mode that stretches the 4:3 image horizontally to display it fully on a 16:9 screen.
