Chapter 3: Motherboard Connections
HDMI Port
The HDMI (High-Definition Multimedia Interface) port is used to display both high definition
video and digital sound through an HDMI-capable display, using the same cable.
Universal Serial Bus (USB) Ports
There are two USB 3.0 ports (USB4/5) and one USB 3.0 Type C port (USB6) on the I/O back
panel. The motherboard also has four front access USB 2.0 headers (USB0/1 and USB2/3).
The onboard headers can be used to provide front side USB access with a cable. Two USB
2.0 cables for front panel support are included with the motherboard.
