Appendix
Active digital keystone correction
Corrects keystone distortion caused when the projected image is not perpendicular to the screen. This method provides not
only horizontal correction, but vertical as well, thus maintaining the original 4:3 aspect ratio and eliminating jag lines.
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 input.
Clock
Clock adjustment is used to adjust vertical noise when clock level is incorrect.
Compatibility
Ability to use with various image signal modes.
Composite sync
Signal combining horizontal and vertical sync pulses.
Dot by dot
Mode that projects images in their native resolution.
Freeze
Function to freeze a moving image.
Gamma correction
Offers richer image viewing with dark scene phase and contrast correction according to image and room brightness. Three
gamma settings are available.
GUI
Graphical User Interface. User interface with graphics that allow easier operation.
Intelligent compression and expansion
High quality resizing of lower and higher resolution images to fit the projector’s native resolution.
Magnification
Digitally zooms in on a portion of an image.
Power save mode function
Function with toggle switch to control the quantity of projected light. Select “ON” or “OFF” to decrease or increase
brightness, power consumption and fan noise.
PDF
Portable Document Format. Documentation format used to transfer text and images from the CD-ROM.
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.
RS-232C
Function to control the projector from the computer by using the RS-232C ports on the projector and computer.
Sync on green
Video signal mode of a computer which overlaps horizontal and vertical sync signal to green color signal pin.
Wireless mouse
Function to operate the mouse control of a computer with the supplied remote control.
XGA resolution
Resolution with 1,024 
 768 pixels that uses the signal of an IBM/AT compatible (DOS/V) computer.
