It does work. I went with the more pricy official Samsung adapter. Best Buy (US) had a 3rd party adapter that was a bit cheaper. Micro usb-type plug on one end (goes into the Tab S), a larger dongle block on the other which takes a full size hdmi cable. That larger block also has a micro-usb port which I believe is intended to allow the Tab to charge. I have not tried that and I think I've read it may or may not charge!!!
