The gmZAN1device utilizes Genesis' patented third-generation Advanced Image Magnification technology as well as
a proven integrated ADC/PLL to provide excellent image quality within a cost effective SVGA/XGA LCD monitor
solution.
As a pin-compatible replacement for the gmB120, the gmZAN1 incorporates all of the gmB120 features plus many
enhanced features; including 10-bit gamma correction, Adaptive Contrast Enhancement (ACE) filtering, Sync On
Green (SOG), and an enhanced OSD.
