Sorry, but it's old news and I've been doing it for some time. In school Wikipedia citing is frowned upon. But it's usually the quickest find.
Since 2008, PC manufacturers have gradually upgraded the PC's controller to support HDMI-output in addition to DVI. Due to electrical and pin compatibility between the DVI and HDMI, only a simple passive adapter (or DVI-D to HDMI cable) is necessary in order for the PC to output HDMI to a compatible HDMI-display (such as a television), and take advantage of HDMI features (such as audio output).
