Q&A: Linking a Samsung Tablet to a TV Can I connect my Samsung Galaxy Tab 2 to my TV with an HDMI cable to play movies? The Samsung Galaxy Tab 2 comes in two versions, a model with 10.1-inch screen and one with a 7-inch display, and you have more options with the larger tablet. For example, Samsung sells a $40 adapter for the larger Galaxy Tab 2 that links the port on the bottom of the tablet to an HDMI cable connected to a compatible HDTV set. You need to supply the HDMI cable yourself, and the adapter needs to be plugged into the tablet's charging cable. However, the adapter does not work with the 7-inch model of the Galaxy Tab 2, which does not support HDMI output. Samsung's own AllShare Play software can stream music, photos and video from its Galaxy Tab devices to televisions that use the Digital Living Network Alliance standard. Samsung's wireless-enabled Smart TV sets support it. If you do not own such equipment, though, this is obviously not much of a solution for getting material from the tablet up on the TV screen. But if using AllShare Play is a possibility for you, About.com has a guide to using the technology. If the movies you want to watch are from the Google Play Store, Google has a help page for watching the videos on a high-definition television set.
