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 was known for their quality analog display output on prior cards and the G is no exception. NET Framework, even if version 2. Typically a second source is needed to provide a picture in picture display, so perhaps this function works when an external DVD player or VCR is hooked up, but it does not work in pure cable mode. This feature is known as “DualHead” and was a decisive edge for Matrox over the card’s competitors at the time.

Matrox took the technology developed from the G project, refined it, and basically doubled it up to form the G processor. Previously Released Drivers for Older Matrox products Drivers in this section are previously released drivers and should be used for trouble shooting purposes only.
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.
The mafrox uses the same Philips TV tuner module found on the other products. This is useful when recording shows while out. EMBM requires either specialized hardware within the chip for its calculations or a more flexible and programmable graphics pipeline, such as later DirectX marel.
Video from live TV can be recorded by clicking on the record icon. Even with initial driver difficulties, Matrox G was very competitive. G was known for being particularly dependent on the host system’s CPU for high 3D performance.
Drivers for older/legacy Matrox products
Matrox made it very clear that they were committed to supporting OpenGL, however, and development rapidly progressed.
Drivers for older operating systems Windows 95, Window 3. Boards shipped with dual analog VGA connectors. Codenamed ” Toucan “, it was a more powerful and refined version of its predecessor, the G Unless otherwise indicated, HF drivers require version 1.
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. Bthat are fully 4X compliant and run at the marvvel speed if the motherboard is capable as well.
Despite the feature, it is inaccessible by DirectX driver. 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.

Only a few games supported the ,arvel, such as Dungeon Keeper 2 and Millennium Soldier: Matrox was known for their quality analog display output on prior cards and the G is no exception. The software can also decode closed caption information which is displayed on two black lines at the bottom of the live TV image.
Internally the G is a bit processor, using what Matrox calls a “DualBus” architecture. Time shifting is mstrox by clicking on the stopwatch icon on the on-screen remote. The G is a video card made by Matroxreleased in September Video capturing was possible but drivers are still based on VfW. It was also equipped with a hardware transform and lighting unit capable of processing 20—30 million triangles per second. Drivers in this section are zipped using the -RP option.
They must be unzipped using the -D option.

Overclocking tests showed that the core was unable to achieve higher speeds than G even though it was manufactured on a newer process. Performance information on this card can be found here. G’s rendering pipelined uses what Matrox called “Vibrant Color Quality 2” VCQ2a functionality in which all internal 3D calculations are done with bit precision.
Beta drivers are not supported by Matrox Graphics Technical Support. Typically a second source is needed to provide a picture in picture display, so perhaps this function works when an external DVD player or VCR is hooked up, but it does not work in pure cable mode.
