Chapter 1 Overview
VX200 is a video processor developed for the display system of large-size LED
displays. With the leading-edge chips of the industry used and 12-bit digital
processing inside, it will bring us clearer images and richer colors. VX200 has
adopted technologies such as Faroudja® DCDI de-interlacing video processing,
Real Color® real color image processing, Faroudja®TureLife™ video image
enhancement, etc. to perfect the display of video image.
The maximum output resolution of a single unit is up to 2048×1152 and it allows to
customize output resolution. VX200 has multiple special switching effects like
signal cut and fade. The size and position of PIP (Picture in Picture) can be set as you
