As said earlier, G suffered at launch from driver problems. From Wikipedia, the free encyclopedia. The G is a video card made by Matrox , released in September 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. This meant that the primary monitor could run much higher resolutions and refresh rates than the secondary. 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.

Only a few games supported the feature, such as Dungeon Keeper 2 and Millennium Soldier: Matrox made it very clear that they were committed to supporting OpenGL, however, and development rapidly progressed.

G’s 3D engine consists of 2 parallel pixel pipelines with 1 texture unit each, providing single-pass dual-texturing capability. 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 video overlays onto the second monitor.

Internally the G is a bit processor, using what Matrox calls a “DualBus” architecture. Where many cards were crippled by blurry output, especially as the resolution and refresh rate increased, the Matrox cards delivered very sharp and clear images. There are no WDM drivers available for this card. It was also equipped with a hardware transform and lighting unit capable of processing 20—30 million triangles per second.


Matrox stopped support for ,axtor GTV early because there was no way to make it fully functional in Windows From Wikipedia, the free encyclopedia. Retrieved from ” https: Boards shipped with dual analog VGA connectors. Matrox tried to make stable drivers for g4500 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.

Matrox G450 Low Profile

Views Read Edit View history. Unfortunately, because of the identical core clock and due to lower memory bandwidth, G was slower than G in games. However, contrary to the video mode’s name, G does not support full DVD decoding hardware acceleration. G was known for being particularly dependent on the host system’s CPU for high 3D performance.

Despite the feature, it is inaccessible by DirectX driver. The goal was to prevent dithering and other artifacts caused by inadequate precision when performing calculations.

EMBM requires either specialized hardware within the chip for its calculations or a more flexible and programmable graphics pipeline, such as later DirectX 8. Due to this lack of industry-wide support, and its toll on the limited graphics hardware of the time, EMBM only saw limited use during G’s time.


A Matrox user going by name Adis hacked original drivers to make the card work under Windows Hardware MJPEG capturing can be unstable but software compression, using a good video codec, gives much better results anyway.

A Matrox “DualBus” chip consists of twin unidirectional buses internally, each moving data into or out of the chip. Findings within a release of Matrox graphics drivers MGA The new chip featured cp 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.

This feature is known as “DualHead” and was a decisive edge for Matrox over the card’s competitors at the time. Matrox only supports HeadCasting feature through the bundled Matrox Digimask software, which have never become popular. Bthat are fully 4X compliant and run at the higher speed if the motherboard is capable as well.
