Intel BLKDH57JG manual PCI Express* x16 Graphics, Digital Visual Interface DVI-I, VGA Displays

Desktop Board Features

Digital Visual Interface (DVI-I)

The DVI-I port supports both digital and analog DVI displays. The maximum supported resolution is 1900 x 1200 (WUXGA). The DVI port is compliant with the DVI 1.0 specification. The DVI analog output can be converted to VGA using a DVI- VGA converter.

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.

Table 4. DVI Port Status Conditions

	DVI Digital (DVI-D)	DVI Analog (DVI-A)
PCI Express x16 Connector Status	Port Status	Port Status(Note)
No add-in card installed	Enabled	Enabled
Non-video PCI Express x1, x4, or x8	Enabled	Enabled
add-in card installed
PCI Express x4, x8, or x16 graphics	Disabled	Disabled
add-in card installed

Note: DVI analog output can be converted to VGA with a DVI-VGA converter.

VGA Displays

The DVI-I port supports VGA displays when a DVI-I to VGA converter is used. The maximum supported resolution is 2048 x 1536 (QXGA).

The DVI-A port is enabled for the POST whenever a monitor is attached, regardless of the HDMI connector status.

PCI Express* x16 Graphics

The Intel Core i5-600 series, Intel Core i3, and Intel Pentium processors in an LGA1156 socket support discrete add-in graphics cards via the PCI Express 2.0 x16 add-in card connector. The board supports the following PCI Express speeds:

•PCI Express 2 frequency of 2.5 GHz which results in 5.0 Gb/s in each direction (500 MB/s) per lane. The maximum theoretical bandwidth on the interface is 8 GB/s in each direction, simultaneously, when operating in x16 mode.

•PCI Express 1.1 frequency of 1.25 GHz resulting in 2.5 Gb/s each direction (250 MB/s) per lane. The maximum theoretical bandwidth on the interface is 4 GB/s in each direction, simultaneously, when operating in x16 mode.
