The 1600SW is a widescreen flat panel video monitor from Silicon Graphics introduced in 1998. It won many awards after release and sold 54,000 units. It is notable for longevity, with used models still actively traded on eBay a decade later, though difficult to adapt the OpenLDI video interface to modern video cards. Formac sold the same monitor bundled with its own OpenLDI graphics adapter as Formac ProNitron 18/500 Radius sold the monitor as the Artica which differs mainly in a translucent white case and a conventional mount. SGI sold the monitor primarily as Model #AM173Y01.
