Monitor switches for OpenLDI

There is a 4-way monitor switch by Dr. Bott called MoniSwitch Pro LDI that allows sharing OpenLDI display among 4 computers, each of which must be equipped with an OpenLDI graphics adapter.

Adapting the 1600SW to Modern Video Cards

OpenLDI is rarely used today, as all popular home and office LCD panel monitors use a DVI

 or VGA standard connector. There are several companies that make adapter boxes which allow continued use of these older displays. All of these adapters were developed for the 1600SW monitor:
  • SGI Multilink Adapter (VGA or DVI) (discontinued)
  • Dr. Bott SGI-Saver (DVI) (discontinued)
  • PIXsolution PIX-Link 1600SW (DVI) (discontinued)
  • GFX-1600SW sold by Niktec (DVI adapter, in passive PCI form factor, also sold built in to 1600SW monitors)


SGI referred to video cards that support the 1600SW's 1600 x 1024 resolution as Super Wide Savvy. Most modern cards have no trouble with this resolution, but on PC based machines, problems and screen distortion can exist during system boot. Apple Macintoshes boot directly into the proper resolution. Thus, with a little work, the 1600SW can be adapted to almost any modern computer.
