The MagnaByte®P170/P170v can be connected to any IBM or IBM
compatible computer equipped with a VGA video output. The
P170/P170v can also be connected to any Apple Macintosh computer
that is equipped with a standard Macintosh video output.
The MagnaByte
®
P170/P170v uses advanced thin-film-transistor liquid
crystal display (TFT LCD) technology and is capable of displaying up to
16,194,277 colors. The fast response time of the P170/P170v’s TFT LCD
provides you with the ability to display sharp, clear, fast-moving images.
The liquid crystal display is a matrix of 921,600 pixels arranged in 480
rows and 640 columns. Each pixel is a single thin-film-transistor that
actively controls the brightness of the light that passes through the pixel.
To protect the P170/P170v from excessive heat, it is equipped with a fan
that is turned on whenever the desktop LCD projector is turned on.
The keypanel and on-screen controls allow you to change the video
source, color, tint, focus, position, volume, tone, etc. of the projected
color image.
