Codenamed ” Toucan “, it was a more powerful and refined version of its predecessor, the G A Matrox user going by name Adis hacked original drivers to make the card work under Windows Internally the G is a bit processor, using what Matrox calls a “DualBus” architecture. G was known for being particularly dependent on the host system’s CPU for high 3D performance. Perhaps the most notable feature of G is its ability to drive two separate monitors to display a single desktop. G’s rendering pipelined uses what Matrox called “Vibrant Color Quality 2” VCQ2 , a functionality in which all internal 3D calculations are done with bit precision.

With regard to its hardware, G’s triangle setup engine, called the “Warp Engine” ironically, was somewhat slower than the counterparts aboard the competition’s cards.

Despite the feature, it is inaccessible by DirectX driver.

G’s 3D engine consists of 2 parallel pixel pipelines with 1 texture unit each, providing single-pass dual-texturing capability. G does have partial support for the DVD video decoding process but it does not perform inverse discrete cosine transform IDCT or motion compensation in hardware the two most demanding steps of the process.

Matrox “HF” drivers have a rich interface that require Microsoft. If you are looking for the most recent drivers, please click here. The goal was to prevent dithering and other artifacts caused by inadequate precision when performing calculations. However, contrary to the video mode’s name, G does not support full DVD decoding hardware acceleration.

Retrieved from ” https: The new chip featured several new and innovative additions, such as multiple monitor output support, an all-around bit rendering pipeline with high performance, further improved 2D and video acceleration, and a new 3D feature known as Environment Mapped Bump Mapping.


Matrox made it very clear that they were committed to supporting OpenGL, however, and development rapidly progressed. The result was the best quality bit and bit color modes available at the time. The DualHead capability not only offered desktop widening but also desktop cloning two screens showing the same thing and a special “DVDMAX” mode which outputs xl overlays onto the second monitor.

It is purely a Direct3D 6. Matrox tried to make stable drivers for several months but with no luck. By shrinking the core, costs are reduced because more chips are made per wafer at the factory, and Matrox can take the time to fix earlier mistakes in the core, and trim or add new functionality. Bthat are fully 4X compliant and run at the higher speed if the motherboard is capable as well.

Matrox was known for their quality analog display output on prior cards and the G is no exception. The situation was eerily similar to what had happened with the older G, with its near-total lack of credible OpenGL support. Previously Released Drivers for Older Matrox mavrel Drivers in this section are previously released drivers and should be used for trouble shooting purposes only.


In cases where “available with OS” is stated, the operating system will install a Matrox driver that will give you basic 2D and 3D functionality, where this driver is supported by Microsoft. Matrox’s award-winning Powerdesk display drivers and control panel integrated Dualhead in a very flexible and functional way that become world-renowned for its effectiveness.

A bit bus reduces the board’s complexity and cost because fewer traces have to be used, and potentially the pin-count of the graphics processor can be significantly reduced if the chip is designed only for a bit bus. It added some new features to DualHead that worked with Internet Explorer to make pages show up on both screens at once.

MGA-G processor added a second pixel pipeline, hardware transform and lighting, and the HeadCasting Engine, a hardware implementation of a vertex shader for accelerated matrix palette skinning.

Internally the G is a bit processor, using what Matrox calls a “DualBus” architecture. Views Read Edit View history.

Perhaps the most notable feature of G is its ability to drive two separate monitors to display a single desktop.
