Intel Desktop Board DH55HC Product Guide

High-Definition Multimedia Interface* (HDMI*)

The HDMI port supports standard, enhanced, or high-definition video, plus multi- channel digital audio on a single cable. It is compatible with all ATSC and DVB HDTV standards and supports 8-channel digital audio. The maximum supported resolution is 1920 x 1200 at 60 Hz refresh (WUXGA). The HDMI port is compliant with the

HDMI 1.3 specification.

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

Digital Visual Interface (DVI-D)

The DVI-D port supports digital DVI displays. The maximum supported resolution is 1920 x 1200 at 60 Hz refresh (WUXGA). The DVI-D port is compliant with the DVI 1.0 specification.

The DVI-D port is only enabled for POST when there are no monitors attached to the VGA or HDMI connectors.

PCI Express* x16 Graphics

The Intel Core i7, Intel Core i5, 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 GEN2 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 GEN1 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.
