Trying to Connect Samsung Galaxy Tab 3 7" to a Tv Help!!

[Android_Krist]

I bought a RocketFish© HDMI Adapter to Connect to my Samsung Galaxy Tab 3 7" and then I connected My HDMI Cord to my TV and to the Adapter, and nothing shows up, it's supposed to mirror the Samsung Galaxy Tab's screen to my TV but it doesn't? Please Help!

Did you turn the Screen Mirroring feature to see if that works?
