Is there a HDMI port on a computer?

The HDMI (High Definition Media Interface) slot is normally found along with the other video output slots either on the back of a desktop casing or on the sides of a laptop. It looks like a USB port, with two small notches missing from the corners of one side.

It is normally standard with modern PC's (within the last 3 years), but would have been an expansion card with older PC's
