Integrated Graphics
Media Accelerator 3100 3D/2D Controller Microsoft DirectX® 9 based with support for Pixel Shader 2.0, 4:1
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
Refresh Rate 85 Hz at up to 1920x1440, 75 Hz at 2048x1536. Varies with mode and
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
Support 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.
