Introduction
The EX-G055A Dual-View Video Enhancing Processor is an advanced video processor to enhance the video quality for multimedia presentations. It is an ideal solution for applications where two video signals must be displayed on a single display. It supports up to nine video inputs, of which two, one digital and one analog, can be outputted simultaneously in Picture-In-Picture (PIP) or Picture-Aside-Picture (PAP) modes. The EX-G055A combines state-of-the-art technologies, such as video de-interlacer, scaler, color management, format conversion, and video switch into one box and allows you to manipulate output images, wherever position and whatever sizes you want for viewing two computers or two video signals or a combination through the control software*.
The embedded scaler converts signals from input sources to match the native resolution of monitors, flat panel displays, projectors as well as user-selectable output settings up to WUXGA (1920 x 1200). Dual outputs are provided in both analog (VGA) and digital (DVI) format, one is connected to remote display and the other is connected to on-site display for real time monitoring.
