Video Memory; Available Video Resolutions - HP P Class 450/500/550/600/650/700/750 Supplementary Manual

• 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.
