VGA/VIDEO PORTABLE PRO

2.1 General Overview

The VGA/Video Portable Pro is a super-compact computer-to-TV video

converter. It transfers graphic images from your computer for display on

a TV or video projector of any size or for recording on a VCR. The Portable

Pro is completely hardware-based—you don’t have to run any computer

software to make it work. It can support both IBM®PC based and Apple®

Macintosh®based systems. In short, it’s perfect for presentations, training,

advertising, education, and a host of other applications.

2.2 Features

• Latest-generation filter technology brings you 100% flicker-free video.

• Pure hardware design—no software necessary, just “plug-and-display.”

• With “automatic mode detection,” the Portable Pro supports horizontal

synchronization rates from 24 KHz to 38 KHz and vertical synchronization

(refresh) rates from 56 Hz to 72 Hz for all colors. This means that it is

compatible with PC systems outputting VGA video at 800 x 600 resolution

(at 35.2 KHz/56 Hz) or 640 x 480 resolution (at up to37.9 KHz/72 Hz).

It is also compatible with computer systems outputting Mac®video at

800 x 600 resolution (“SVGA mode”) at 35.2 KHz/56 Hz or 640 x 480

resolution (at either 35 KHz/66 Hz or 31.5 KHz/60 Hz).

• Supports NTSC (AC331A) or PAL (AC331AE) video for the TV output.

• You can select ZOOM (regular magnification) or UNZOOM

(underscan—640 x 480 is 100% visible edge-to-edge) display; there is no

flickering or reduced resolution in either mode.

• You can adjust the brightness and horizontal position of your images.

• Since it has a computer-video output port, images can be viewed on a

monitor and a TV simultaneously.

• It has a variety of TV-video output ports, so it can be connected to almost

any type of TV, even those with special high-quality video interfaces.
