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.
Optimizes projected computer images by automatically adjusting certain characteristics.
Initial setting image projected when no signal is being input.
Clock adjustment is used to adjust vertical noise when clock level is incorrect.
Ability to use with various image signal modes.
Signal combining horizontal and vertical sync pulses.
Function to digitally correct a distorted image when the projector is set up at an angle.
Mode that projects images in their native resolution.
Function to adjust an image without keeping a native aspect ratio other than 4 : 3, and project it in a 4 : 3 ratio.
Function to freeze a moving image.
Graphical User Interface. User interface with graphics that allow easier operation.
Function to convert an image between “Interlaced” and “Progressive” scan displays.
Intelligent compression and expansion
High quality resizing of lower and higher resolution images to fit the projector’s native resolution.
Function to transmit still images from a computer, hand-held PC or digital still camera via infrared communication for
“Wireless Presentations”.
Standard protocol for wireless communication.
Standard format (protocol) for transmission of images.
Digitally zooms in on a portion of an image.
Portable Document Format. Documentation format used to transfer text and images from the CD-ROM.
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.
Helpful tools used to emphasize keypoints throughout a presentation.
Function to control the projector from the computer by using the RS-232C ports on the projector and computer.
The image displayed when the projector is turned on.
Displays the settings of each adjustment item.
Synchronizes the resolution and phase shift of two signals. When receiving an image with a resolution different from that of
the computer, the projected image may be distorted.
Video signal mode of a computer which overlaps horizontal and vertical sync signal to green color signal pin.
Function to operate the mouse control of the computer with the supplied remote control.
The resolution with 1,024
2
768 pixels that uses the signal of an IBM/AT compatible (DOS/V) computer.
