Technical Specifications - Graphics
Integrated Graphics	3D/2D Controller	Microsoft DirectX® 9 based with support for Pixel Shader 2.0, 4:1
Media Accelerator 3100		anisotropic filtering, Gaussian texture filtering, shadow maps, volumetric
		textures, double-sided stencil buffers, and 4 pixel pipes.
	VGA Controller	Integrated
	Bus Type	PCI Express™ x16 (If an external graphics card is installed in a PCI or
		PCIe x1 slot, the internal graphics can be enabled or disabled using the
		system's BIOS setup utility. If a graphics card other than an
		SDVO/ADD2 card is installed in the PCI Express™ x16 slot, the internal
		graphics cannot be enabled).
	RAMDAC	Integrated, 350 MHz (2048x1536@75 Hz)
	Memory	Graphics memory is shared with system memory. Graphics memory
		usage varies depending on the amount of system memory installed and
		system load. 8 MB is pre-allocated for graphics use at system boot time.
		Additional memory is allocated for graphics as needed using Intel's
		Dynamic Video Memory Technology (DVMT), to provide an optimal
		balance between graphics and system memory use.
		System memory equal or greater than 512 MB
		8 MB pre-allocated + 248 MB DVMT = max frame buffer of 256 MB
	Overlay Planes	Single overlay support with 5x3 filtering
	Maximum Color Depth	32 bits/pixel
	Maximum Vertical	85 Hz at up to 1920x1440, 75 Hz at 2048x1536. Varies with mode and
	Refresh Rate	configuration. See table below.
	Multi-display Support	Support for one CRT via the motherboard's VGA connector on SFF and
		CMT. USDT includes support for an additional DVI-D display. Support
		for an additional display on SFF/CMT can be accomplished with the
		addition of SDVO/ADD2 option installed in PCIe x16 slot.
	Graphics/Video API	Microsoft DirectX®9, DirectXVA®, VMR9, GDI/GDI+; OpenGL® 1.4.

1 Modes listed are supported with a single active display. The supported mode list for multiple active displays is a subset of this list. Not all modes will support video playback and some supported modes may use software MC (motion compensation) rather than hardware MC. Not all modes will support 3D acceleration depending on the system configuration (e.g., resolution selected, size of frame buffer, number of installed memory modules, etc.).

NOTE: Other resolutions and refresh rates may be selectable but are not recommended.
