Intel Desktop Board DH61WW Technical Product Specification 
20
 
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. 
1.7.2  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.
