Intel Desktop Board DQ67OW Technical Product Specification 1.7 Graphics Subsystem The board supports system graphics through either Intel Graphics Technology or a PCI Express 2.0 x16 add-in graphics card. 1.7.1 Integrated Graphics The board supports integrated graphics through the Intel® Flexible Display Interface (Intel® FDI) for processors with Intel Graphics Technology. NOTE If using a processor with integrated graphics, the board will support only two of the integrated graphics interfaces simultaneously: DisplayPort, DVI-I, DVI-D. NOTE The board will support up to two integrated graphics interfaces plus one PCI Express Graphics card simultaneously with required changes to the BIOS setup. 1.7.1.1 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. 1.7.1.2 Digital Visual Interface (DVI-D) The DVI-D port supports only digital DVI displays. The maximum supported resolution is 2048 x 1536 at 75 Hz refresh (QXGA). The DVI-D port is compliant with the DVI 1.0 specification. 1.7.2 PCI Express x16 Graphics The Intel Core i7, Intel Core i5, Intel Core i3, and Intel Pentium processors in an LGA1155 socket support discrete add in graphics cards through the PCI Express 2.0 x16 graphics connector: • Supports PCI Express GEN2 frequency of 2.5 GHz resulting in 5.0 Gb/s each direction (500 MB/s) per lane. Maximum theoretical bandwidth on interface is 8 GB/s in each direction, simultaneously, when operating in x16 mode. • Supports PCI Express GEN1 frequency of 1.25 GHz resulting in 2.5 Gb/s each direction (250 MB/s) per lane. Maximum theoretical bandwidth on interface is 4 GB/s in each direction, simultaneously, when operating in x16 mode. For information about PCI Express technology Refer to http://www.pcisig.com 18

PCI Express 2.0 x16 add-in graphics card.
1.7.1
Integrated Graphics
The board supports integrated graphics through the Intel
®
Flexible Display Interface
(Intel
®
FDI) for processors with Intel Graphics Technology.
NOTE
If using a processor with integrated graphics, the board will support only two of the
integrated graphics interfaces simultaneously: DisplayPort, DVI-I, DVI-D.
NOTE
The board will support up to two integrated graphics interfaces plus one PCI Express
Graphics card simultaneously with required changes to the BIOS setup.
1.7.1.1
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.
1.7.1.2
Digital Visual Interface (DVI-D)
The DVI-D port supports only digital DVI displays. The maximum supported resolution
is 2048 x 1536 at 75 Hz refresh (QXGA). The DVI-D port is compliant with the DVI 1.0
specification.
1.7.2
PCI Express x16 Graphics
The Intel Core i7, Intel Core i5, Intel Core i3, and Intel Pentium processors in an
LGA1155 socket support discrete add in graphics cards through the PCI Express 2.0
x16 graphics connector:
•
Supports PCI Express GEN2 frequency of 2.5 GHz resulting in 5.0 Gb/s each
direction (500 MB/s) per lane.
Maximum theoretical bandwidth on interface is
