    x86-based system: Output of the DirectX VA MPEG acceleration process must be available as an input to the VMR renderer. This can either be in the form of a Direct3D texture or as an input to the color conversion BLTer.

    Note: This requirement does not apply to devices created for 64-bit systems.

    [GRPH-0165]
    B4.1.4.4 Adapter supports minimum screen resolution

    [GRPH-0168]

    Minimum resolution is 1024 × 768 × 32 bpp, double buffered in both 2-D and 3-D modes with a 32-bit Z-buffer in 3-D mode.

    Adapter meets VESA specifications for ergonomic timing rates (optionally, 59.94 Hz variants of the 60 Hz timings); screen resolution and local memory capacity meet minimum requirements.

    After July 1, 2002, integrated solutions must support this minimum requirement; until July 1, 2002, integrated solutions can have a minimum screen resolution of 1024 × 768 at a color depth of 24 bpp for 2-D, and 1024 × 768 at a color depth of 16 bpp with a 16-bit Z-buffer in 3-D mode.



    Mobile PC Note: Requirements are defined in B4.1.4.13
    B4.1.4.5 Color support

    [GRPH-017x]

    • All supported color depths are enumerated. [GRPH-0170]

    • Adapter supports gamma correction performed in hardware at 24 bpp or 32 bpp without using VGA resources. [GRPH-0178]

    • Driver supports dynamic color bit-depth change. [GRPH-0206]

    • Graphics adapter operates properly and does not fail when Windows requests that it change the color depth or resolution; a restart must not be required to accomplish this. [GRPH-0206]
    B4.1.4.6 Device configuration and detection requirements

    [GRPH-01xx; SDG3]

    • Graphics operations use relocatable registers only. [GRPH-0171]

    • Primary graphics adapter works normally with default VGA mode driver. [GRPH-0166; SDG3:75, 76]

    • Driver does not bypass any Microsoft-provided system components. [GRPH-0205; see FAQ B4.1.5.4]

    • Adapter supports DDC monitor detection, and option ROM supports VESA Enhanced Display Data Channel Standard (EDDC), Version 1.0, Level 2B protocols (DDC2B). [GRPH-0179

    Mobile PC Note: Requirements are defined in B4.1.4.13.

    • Frame buffer can be accessed directly by applications. [GRPH-0182]

    • System supports conflict resolution, VGA compatibility, and extended registers. [GRPH-0196]

    • BIOS supports large frame buffers for graphics adapters. [GRPH-0200]

    • Graphics adapter complies with VESA BIOS Extensions/Core 2.0 extensions for power management. [GRPH-0204]
    B4.1.4.7 Basic 2-D hardware acceleration requirements

    [GRPH-018x]

    • Hardware supports transparent blter. [GRPH-0183]

    • Hardware provides support to prevent tearing. [GRPH-0184]

    • Chips support linear packed-pixel frame buffer, relocatable above 16 MB. [GRPH-0197]
    B4.1.4.8 Adapter supports hardware-accelerated 3-D graphics

    [GRPH-018x]

    Including these additional 3-D requirements for hardware support:



    • Multi-texturing. [GRPH-0186]

    • Source alpha blending and destination alpha blending; required texture size increases to 1024×1024 for all texture operations. [GRPH-0185, GRPH-0188]

    After July 1, 2002, integrated solutions must support destination alpha blending.
