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.
