Progressive

An image display system used to display the entire screen per scan. When an interlace signal (video signal) that displays one screen by two scans (one for odd lines and one for even lines) is input, progressive processing is required. When the progressive function is turned off, one screen is displayed using image signals per interlace signal, deteriorating the vertical resolution of the image. When the progressive function is turned on, one screen is displayed using image signals per two interlace signals, improving the vertical resolution of the image. Turn off the progressive function when flickering and horizontal lines are noticeable on a fast-moving picture.

Resolution

The number of dots (horizontal dots x vertical dots) that can be displayed on a computer is called “resolution of display”. Resolution indicates the size of the display area (amount of information).

Number of pixels in each resolution

Selecting SXGA+ (1400 dots x 1050 dots) as the display resolution of the computer allows this projector to project high-resolution images. If your computer does not have the SXGA+ option, select the maximum resolution among the selectable options.

Gamma Correction

A tone adjustment system used during projection of image data. The gamma correction function works effectively when portions of an image are obscure because they are too light or dark.

This projector supports manual gamma correction, automatic gamma correction, and dynamic gamma correction.

DVI-I

A digital video signal connection interface. This interface allows digital data to be sent and received without conversion to analog data, assuring high image quality with no signal degradation. The DVI-I (integrated) connector can be used to send and receive analog RGB video signals in addition to digital signals.
