ELSA SYNERGY II and GLoria II Graphics Cards Introduction • 3D standards • Hardware accelerated OpenGL • 32 MB of memory installed on the graphics card • Standards: VESA Video BIOS, DPMS, DDC2B, Plug & Play. • Video standards: DirectDraw, ActiveMovie 1.0, DirectShow (ActiveMovie 2.0). Video Memory The video memory 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. The Z-Buffer stores depth information for each pixel. The NVIDIA RIVA TNT2 graphics processor dynamically allocates the memory. The higher the resolution (e.g., 1920 1080)and the deeper the Z-Buffer (32-bit max.), the less memory is available for texture. Available Video Resolutions 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 which are supported. Table 1-1.
