Genoa was a founding member of the Video Electronics Standards Association (VESA) and was instrumental in the development of Super VGA.

He was named Genoa's president and served that role until 1987, when he left to found Trident Microsystems, a fabless semiconductor company, in Mountain View, California.

[9] In early 1986, they released the Spectra EGA, which InfoWorld evaluated as closely mimicking IBM's original Enhanced Graphics Adapter card—down to emulating its bugs when running certain software such as Lotus 1-2-3.

[10] In late 1986, the company released the Genoa SuperEGA board featuring their own bespoke chipset, which extended IBM's EGA standard by adding a resolution mode capable of displaying graphics at 640 by 480 pixels.

These cards were compatible only with the professional multisync CRT monitors just coming on the market at the time but eliminated the perceived flicker that CRTs displaying 60 MHz signals tended to exhibit.

Eventually realized as the Genoa Embedded Information Appliance (GEIA), it was marketed for use in kiosks in financial institutions and insurance companies, as thin clients for schools, and as set-top boxes for home use.
