The diagram below shows the 3Dlabs Oxygen GVX1 graphics card .
Video Memory
The video memory, also known as SGRAM, is a local block of RAM for
holding major data structures: Frame Buffer (double buffer), Z-Buffer and
T-Buffer (Texture Buffer). The Frame Buffer holds one frame steady on the
screen while the next one is being processed, while the Z-buffer stores
depth information for each pixel.
Available Video Resolutions
The number of colors supported is limited by the graphics device and the
video memory. The resolution/color/refresh-rate combination is limited by a
combination of the display driver, the graphics device, and the video
memory. If the resolution/refresh-rate combination is set higher than the
display can support, you risk damaging the display. The table below
summarizes the 3D video resolutions and refresh rates that are supported.
