Unfortunately Matrox never described the functionality of this component in-depth so little is known about it. Retrieved from ” https: Unfortunately, because of the identical core clock and due to lower memory bandwidth, G was slower than G in games.

There is also a timer that can be set to automatically record a specific channel at a certain time. By using this site, you agree to the Terms of Use and Privacy Policy. Overall the time shifting software seemed to work rather well.

Matrox tried to make stable drivers for several months but with no luck.

Matrox G – Wikipedia

Time shifting is enabled by clicking on the stopwatch icon on the on-screen remote. From Wikipedia, the free encyclopedia. This feature is known as “DualHead” and was a decisive edge for Matrox over the card’s competitors at the time.

Upon taking a snapshot, the live TV image freezes momentarily and name of the saved image is displayed over the TV. This is an evolution of G’s “DualBus”, which had been bit. The G is a video card made by Matroxreleased in September G was known for being particularly dependent on the host system’s CPU for high 3D performance. It does this by improving on the 96 constant registers specified for by DirectX 8. Aspect ratio can be altered to a few different settings traditional and wide screen but can not be defined by the user.


G’s 3D engine consists of 2 parallel pixel pipelines with 1 texture unit each, providing single-pass dual-texturing capability. Performance information on this card can be found here.

This is useful when recording shows while out. Boards shipped with dual analog VGA connectors.

Retrieved from ” https: 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. This was the same as G The chip had 3 pixel pipelines with 3 texture units each. Despite the feature, it is inaccessible by DirectX driver. 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 prevented us from sizing the window to marfel liking but also prevented image stretching or skewing as a result of an altered aspect ratio.

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 mstrox steps of the process.


It is purely a Direct3D 6. Log in Don’t have an account? This was attributed both to its architecture and to the poor drivers it relied on for much of its life especially OpenGL ICD.

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. Hardware MJPEG capturing can be unstable but software matrpx, using a good video codec, gives much better results anyway.

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. A Matrox “DualBus” chip consists of twin unidirectional buses internally, each moving data into or out of the chip.

MGA-G processor added a second pixel pipeline, hardware transform and lighting, and the HeadCasting Engine, a hardware marveo of a vertex shader for accelerated matrix palette skinning. Even with initial driver difficulties, Matrox G was very competitive.
