StarTech.com DisplayPort 1.2 to HDMI Adapter - 4K 30Hz - Active Audio Video Converter for DP laptop computers and HDMI Monitor Displays (DP2HD4KS) - video converter

Connect an HDMI monitor to a DisplayPort video source. The DP2HD4KS DisplayPort to HDMI adapter enables you to connect a DisplayPort-equipped desktop or laptop computer, such as the HP EliteBook 8570p / 8470p, to an HDMI display. This adapter is compatible with DisplayPort 1.2 & HDMI 4K @ 30 Hz and as a result can support video resolutions up to Ultra HD (4K) as well as the accompanying digital audio up to 7.1 channel surround sound.
With support for resolutions up to Ultra HD (4K) the DP to HDMI adapter ensures you can convert DisplayPort to HDMI while maintaining an astonishing picture quality four times the resolution of high-definition 1080p. The adapter is also backward compatible with previous DisplayPort revisions 1.0/1.1 with support for resolutions up to 1080p.
For a hassle-free setup the DisplayPort to HDMI adapter allows for plug-and-play installation without any additional software or drivers. Plus, with a small footprint and lightweight design, the adapter maximizes portability.
To ensure compatibility with any DisplayPort output the DP adapter offers an active conversion. Active video conversion is required to maintain 4K resolutions when converting DisplayPort to HDMI. An active DP adapter is also ideal for outputting 1080p video resolutions by ensuring compatibility with graphics cards that are not capable of outputting multi-mode DP++ signals (e.g. ATI Eyefinity).
