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.).

Integrated
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).
Integrated, 350 MHz (2048x1536@75 Hz)
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
Single overlay support with 5x3 filtering
85 Hz at up to 1920x1440, 75 Hz at 2048x1536. Varies with mode
and configuration. See table below.
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.
