SPDIF header, providing
SPDIF audio output to HDMI
VGA card, allows the system to
connect HDMI Digital TV/
projector/LCD devices. Please
connect the SPDIF connector of
HDMI VGA card to this header.
This connector supports a
Trusted Platform Module (TPM)
system, which can
securely store keys, digital
certificates, passwords, and
data. A TPM system also helps
enhance network security,
protects digital identities, and
ensures platform integrity.
There is one header on this
motherboard. Each
header can support two ports.
