Intel Desktop Board DG41AN Technical Product Specification • Display ⎯ Supports digital and analog displays up to 2048 x 1536 at 75 Hz refresh (QXGA); also supports 1920 x 1080 resolution for full High Definition video playback quality ⎯ Dual independent display support 1.6.1.2 Dynamic Video Memory Technology (DVMT 5.0) DVMT enables enhanced graphics and memory performance through highly efficient memory utilization. DVMT ensures the most efficient use of available system memory for maximum 2-D/3-D graphics performance. The amount of system memory allocated to DVMT varies depending on the amount of total system memory installed as well as the operating system being used. For Microsoft Windows Vista*, a minimum of 128 MB can be allocated to DVMT and a maximum of over 2 GB can be allocated to DVMT with the correct amount of memory installed. DVMT returns system memory back to the operating system when the additional system memory is no longer required by the graphics subsystem. DVMT will always use a minimal fixed portion of system physical memory (as set in the BIOS Setup program) for compatibility with legacy applications. An example of this would be when using VGA graphics under DOS. Once loaded, the operating system and graphics drivers allocate additional system memory to the graphics buffer as needed for performing graphics functions. NOTE The use of DVMT requires operating system driver support. 1.6.1.3 Configuration Modes The video modes supported by this board are based on the Extended Display Identification Data (EDID) modes of the monitor to which the system is connected. Standard monitors are assumed. 1.6.1.4 Analog Display (VGA) The VGA port supports analog displays. The maximum supported resolution is 2048 x 1536 (QXGA) at a 75 Hz refresh rate. The VGA port is enabled for POST whenever a monitor is attached, regardless of the DVI-D connector status. 1.6.1.5 Digital Visual Interface (DVI-D) The DVI-D port supports digital DVI displays. The maximum supported resolution is 2048 x 1536 (QXGA) at a 75 Hz refresh rate. The DVI port is compliant with the DVI 1.0 specification. 20

Dynamic Video Memory Technology (DVMT 5.0)
DVMT enables enhanced graphics and memory performance through highly efficient
memory utilization.
DVMT ensures the most efficient use of available system memory
for maximum 2-D/3-D graphics performance.
The amount of system memory
allocated to DVMT varies depending on the amount of total system memory installed
as well as the operating system being used.
For Microsoft Windows Vista*, a
minimum of 128 MB can be allocated to DVMT and a maximum of over 2 GB can be
allocated to DVMT with the correct amount of memory installed. DVMT returns system
memory back to the operating system when the additional system memory is no
longer required by the graphics subsystem.
DVMT will always use a minimal fixed portion of system physical memory (as set in the
BIOS Setup program) for compatibility with legacy applications.
An example of this
would be when using VGA graphics under DOS.
Once loaded, the operating system
and graphics drivers allocate additional system memory to the graphics buffer as
needed for performing graphics functions.

NOTE
The use of DVMT requires operating system driver support.
