Don't assume that all of these very basic devices will work as intended, even the more expensive ones. (Apple calls its version Thunderport) to HDMI (almost ubiquitous in video displays and "big screen TVs" these days). But it works. Use it to connect MY Mac laptop to play streaming video on my 47" Vizio display. Bought another more expensive multipurpose adapter (HDMI, DVI and VGA) which was DOA. It does not work. HDMI from your laptop or other mini port display? Take this one.
