3.3 Graphics-Controller
The graphics controller is integrated in the Geode LX and does high performance 2D-graphics handling. CRT
monitors can be used as well as TFT- or LVDS displays. Therefore, different connectors are on the board. It is
possible to switch between CRT and TFT via BIOS or driver settings. It is also possible to use a CRT and a
TFT/LVDS display simultaneously (driver setting), but only with the same graphics content on both displays.
The Hurricane LX800 supports 3,3V and 5V TFT displays up to 18bit, and LVDS displays with 18/24bit interfaces
with unconventional signal configuration. The display type and resolution can be selected in BIOS
