Intel Desktop Board DH55TC Product Guide High-Definition Multimedia Interface* (HDMI*) The HDMI port supports standard, enhanced, or high-definition video, plus multichannel 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. Audio Subsystem The board supports Intel High Definition Audio through a Realtek ALC888S audio codec as well as through the HDMI interface. The Realtek ALC888S-based audio subsystem provides the following features: • Advanced jack sense for the back panel audio connectors that enables the audio codec to recognize the device that is connected to an audio port. The back panel audio connectors are capable of retasking according to the user's definition, or can be automatically switched depending on the recognized device type. • Stereo input and output via back panel connectors • Headphone and Mic in functions for front panel audio connectors • A signal-to-noise (S/N) ratio of 90 dB The board provides onboard audio headers and back panel connectors. 16
