Glossary Advanced intelligent compression High quality resizing of lower and higher resolution images to fit the projector's native resolution. Anti-theft In case the projector is stolen, this function disables projection of images if the correct keycode is not 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 automatically 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 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. Digital Shift Shifts image up or down easily by , but- tons 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. DVI (Digital Visual Interface) Display digital interface that also supports Analog interfaces. Freeze Temporarily freezes a moving image. 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 GAME. Keylock Level Mode that can lock the operation of projector buttons to prevent mischief. Keystone correction Function to digitally correct a distorted image when the projector is set up at an angle, smoothens out jaggies on keystone images and compresses the image not only horizontally but vertically keeping the 4:3 aspect ratio. 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 presentations. 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. Smart Stretch Projects the image fully in a 16:9 screen by enlarging 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 DLP features, so that the images are displayed in a natural tint based on an original image, when switching to the "sRGB" mode. Startup Image The image displayed when the projector is turned on. Status function Displays the settings of each adjustment item. Stretch Mode that stretches the 4:3 image horizontally to display it fully on a 16:9 screen. -81 Appendix
