The VX1-1600SW was a special version of 3D Labs excellent Oxygen VX1 series of graphics cards. Available only as a PCI card, the VX1-1600SW came with a standard HD15 connector, for normal analogue VGA displays, and a special LVDS connector, for a high quality digital connection to Silicon Graphics' award winning 1600SW TFT display.

The VX1-1600SW was also badged as a Formac PROformance card, which was available for Apple's PowerMac desktop machines.

The  VX1-1600SW will work with Windows NT, 2000, and XP, and there are also drivers available for 95, 98, ME, Linux, and OS X and Mac OS 9.

The card itself conforms to the PCI 32-bit 33/66 MHz Version 2.1 specification, which means it will work with 5V or 3.3V PCI slots. This makes the card ideal for adding a second 1600SW SGI monitor to the Silicon Graphics 320 and 540 Visual Workstations.

Although dated, the VX1-1600SW will still provide excellent performance for normal desktop tasks, and will perform adequately for older games. It will struggle with the graphics demands for newer 3D titles and heavy graphics work, however.

If you're looking for a cheap option to use the excellent 1600SW display on a desktop, however, it can't be beaten, and in this role provides excellent value for money.
