13w3 to SVGA converter cables
Both SUN and SGI machines from a certain era use 13w3 connectors either on the monitor or the workstation. There have been reports of SUN cables not working with SGI machines and there are contradicting reports. To be safe use a SGI 13W3 cable, although the originator of this wiki entry has swapped a SUN Blade 1000 and Octane cable for kicks with Octane dealing with it but the SUN not. Your milage may vary.
Wikipedia discusses 13W3 here.
Sync on Green
Most SGI machines produce a sync on green signal (SOG). Many monitors will not handle this and either no picture or a green tinted display will occur.

General comments (taken from nekochan posts)
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, despite the difficulty of adapting the monitor to run with modern video cards, due to the 1600SW's OpenLDI video interface.
Formac sold the same monitor bundled with its own OpenLDI graphics adapter as Formac ProVitron 18/500. Radius sold the monitor as the Article which differed mainly in having a translucent white case and a conventional mount. SGI sold the monitor primarily under Model #AM173Y01.
The 1600SW was revolutionary for its time, featuring a 17.3 inch diagonal wide screen panel in a market then dominated by CRT monitors. The 1600SW had a 16:10 aspect ratio (referred to by SGI as SuperWide) with a resolution of 1600 x 1024 pixels. The refresh rate was 60 Hz in 24-bit color and 110 dpi (which makes for a smaller dot pitch than most competitive monitors). The 1600SW shared the same styling motif as the SGI Visual Workstation 320, 540 and O2, with a unique (and troublesome) off-center mount. The display won a dozen international awards and despite its age, it still compares well to modern displays produced a decade later. At introduction the 1600SW cost in the neighborhood of $2500.

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 Digital Visual Interface (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.
