Intel Desktop Board DQ35JO Technical Product Specification

• Display

⎯ Supports analog displays up to 2048 x 1536 at 75 Hz refresh (QXGA)

⎯ Dual independent display support

⎯ DDC2B compliant interface with Advanced Digital Display 2 card or Media

Expansion Card (ADD2/MEC), support for TV-out/TV-in and DVI digital display

connections

1.6.1.2 Dynamic Video Memory Technology (DVMT)

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. Up to 287 MB of system memory can be

allocated to DVMT on systems that have 512 MB or more of total system 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 Digital Video Interface (DVI)

The DVI-D port supports only digital video output. If a DVI-I display is connected,

only the digital signal will be displayed. The maximum supported resolution is 1600 x

1200 at 60 Hz. The DVI port is compliant with the DVI 1.0 specification and supports

High Definition Content Protection (HDCP) version 1.1.

Depending on the type of add-in card installed in the PCI Express x16 connector, the

DVI port will behave as described in Table 4.
