Intel Desktop Board DQ57TML Technical Product Specification
18
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.
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, Intel Pentium processors, and Intel Xeon
processors 3400 series in an LGA1156 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.
