7.5 Matrox MGA-G400 PCI/AGP

The Matrox G400 graphics device provides a high performance PCI/AGP VGA- compatible video device. The device provides a fully functional set of PCI configuration registers, and a 2D drawing engine. The AGP interface is currently somewhat minimal, and is not capable of generating neither AGP cycles nor AGP-specific modes at this time.

High performance device drivers are available for most operating systems (Windows, Linux, and Solaris). The Matrox G400 supports full acceleration of all GDI and DirectDraw functions.
