For the simplest and most discreet installation, this 6 ft. Manhattan 153188 1080p DisplayPort to HDMI Cable connects your DisplayPort video source to the HDMI port on your display. It doesn’t need a power source, unlike some converter dongles that require active power and separate bulky video cabling. This cable lets you enjoy movies on a big-screen HDTV, extend your desktop to a second monitor for an expanded workspace or show presentations on a projector at school or work without needing any other adapter or converter.
