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.
B4.1.4.3 If digital video interface is supported, implementation follows Digital Visual Interface 1.0
[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.
