Does DisplayPort carry sound as HDMI does


Does DisplayPort carry sound as HDMI does?
Specifically, I am looking at Lenovo Laptops T410 or T510.

I'm wondering if the spec permits for audio over DP, and if possible whether the Lenovo laptops I mentioned implement it.

Best Answer

Yes, the DisplayPort spec is an audio/video interconnect spec. It can carry both audio and video over a single connection.

It is rare a laptop implements audio-out over a digital video interconnect. My MacBook Pros don't do it over their DisplayPort outputs. More recent MacBook models reportedly may support audio-over-DisplayPort.
