1.3.1.3 High Definition Multimedia Interface* (HDMI*)
The High-Definition Multimedia Interface (HDMI) is provided for transmitting
uncompressed digital audio and video signals to television sets, projectors and other
video displays. It can carry high quality multi-channel audio data and all standard and
high-definition consumer electronics video formats. The HDMI display interface
connecting the processor and display devices utilizes transition minimized differential
signaling (TMDS) to carry audiovisual information through the same HDMI cable. The
processor HDMI interface is designed according to the High-Definition Multimedia
Interface Specification with 3D, 4K, Deep Color, and x.v.Color.
The maximum supported resolution is 4096 x 2304 @ 24Hz or 2560 x 1600 @ 60Hz.
The HDMI interface supports the HDMI 1.4a specification.
Depending on the type of add-in card installed in the PCI Express x16 connector, the
HDMI port will behave as described in Table 4.

Note: May require BIOS setup menu changes.
1.3.1.4 DisplayPort*
DisplayPort is a digital communication interface that utilizes differential signaling to
achieve a high bandwidth bus interface designed to support connections between PCs
and monitors, projectors, and TV displays. DisplayPort is suitable for display
connections between consumer electronics devices such as high definition optical disc
players, set top boxes, and TV displays. DisplayPort output can also be converted to
HDMI using a DisplayPort-HDMI converter. The DisplayPort interface supports the 1.2
specification, including Multi-Stream Transport (MST) for monitor daisy-chaining.
DisplayPort’s maximum supported display resolution is 3840 x 2160 @ 60Hz.

1.3.1.5 High-bandwidth Digital Content Protection (HDCP)
HDCP is the technology for protecting high definition content against unauthorized
copy or interception between a source (computer, digital set top boxes, etc.) and the
sink (panels, monitor, and TVs). The PCH supports HDCP 1.4 for content protection
over wired displays (HDMI, DVI, and DisplayPort).

Product Description
