Samsung advertises this for use with Galaxy Tab A tablets. Well after spending almost 3 hours on the phone with various support services, Tab A does not support HDMI output. Of course, that's too expensive for a simple HDMI cable, but even more so when it doesn't work. It would be nice if Samsung would update the support for its products. The support rep finally admitted it wouldn't work after trying several adapters and finally breaking down to buy a Samsung branded cable which they said I had to buy for it to work.
