Appian Graphics

Founded in 1994, Appian Graphics was a supplier of multi-monitor graphics accelerators.

The company was best known for its Jeronimo and Gemini product lines, and for the HydraVision display management software. The main competitor for Appian on the multi-monitor solutions market was STB Systems.

The company was acquired in July 2001 by Colorgraphic.

Appian Graphics originally developed HydraVision in late 90s for their multi-head display solutions. ATI acquired HydraVision in July 2001 along with Appian's HydraVision team to join its then-new dual-head Radeon 7500 and 8500 series.
