Texture format 8:8:8:8 alpha RGB (ARGB). [GRPH-0187]
After July 1, 2002, integrated solutions must support texture format 8:8:8:8 ARGB.
-
Z comparison modes and Direct3D-compatible formats. [GRPH 0189]
-
Fog blending term is calculated on a per-pixel basis rather than per vertex, and is either range-based (range-based fog) or depth-based (pixel fog).
Driver support for triangle strips and fans. [GRPH-0185.3]
After July 1, 2002, integrated solutions must support per-pixel fog; until January 1, 2002, integrated solutions can implement only per-vertex fog.
After July 1, 2002, integrated solutions must support MODULATEALPHA texture combinations.
Also, multitexture support with fogging and alpha blending are not required.
[GRPH-0185, GRPH-0187, GRPH-0188]
Mobile PC Note: Requirements are defined in B4.1.4.14.
B4.1.4.9 Graphics adapter uses PCI, AGP, or another high-speed bus
[GRPH-0163]
-
Equivalent of AGP 2X required for discrete solutions; AGP 1X or equivalent required for integrated solutions. [GRPH-0163]
-
PCI device supports IRQ and correctly populates PCI BARs. [GRPH-0201]
-
PCI system-board graphics device PCI configuration space must be visible to the Plug and Play enumeration software. [GRPH-0202; see also FAQ B4.1.5.7]
B4.1.4.10 TV output capability, if present, meets requirements -
Adapter supports underscan scaling. [GRPH-0190]
Mobile PC Note: This requirement does not apply to mobile PC platforms.
-
Adapter supports flicker filter and is required to take a 1024 x 768 32-bpp input and downscale it to the TV out resolution (NTSC or PAL). [GRPH-0192]
-
Adapter with television output supports both 1024 x 768 at 32 bpp VGA and television output simultaneously. [GRPH-0194]
-
Software supports positioning. [GRPH-0191]
Mobile PC Note: This requirement does not apply to mobile PC platforms.
B4.1.4.11 Graphics subsystem support for TV or DVD-Video playback, if present, meets performance requirements
[GRPH-0207, 0208, GRPH-0395]
For the adapter to achieve the required performance when rendering Line21, the DDCAPS_CANBLTSYSMEM cap needs to be set in the display adapter.
