Product Brief
gm3120
The gm3120 device is an all-in-one image processor targeted on
LCD monitors with resolutions up to SXGA (1280x1024). The
gm3120 leverages Genesis patented advanced image-
processing technology as well a Genesis proprietary Ultra-
Reliable DVI compliant digital receiver to provide excellent image
quality. In addition, an integrated microcontroller is provided.
These features yield a very simple and cost-effective solution for
high-end, digital interface LCD monitors.
