If your Android device and your TV both have CAST functionality, then you can CAST or Mirror the image on your Android to the TV. This page gives more information on how to CAST your Android to a TV – Cast from Android to TV
If you don’t have the option of using CAST, then connect your Android device to TV with a wireless connection using an existing WIFI network AND if your TV is DLNA compatible.
What is DLNA? The Digital Living Network Alliance (DLNA) enables sharing of digital media between devices such as computers, printers, cameras, cell phones, and other multimedia devices.
There are many TVs that come with DLNA including Televisions from Samsung (w/ AllShare), LG, Sony BRAVIA, Philips, Panasonic Viera, and Toshiba.
The Samsung Android devices include AllShare pre-installed and easily connects to a Samsung TV with AllShare via your Wi-Fi network.
Additional DLNA apps that work well are iMediaShare and also UPnPlay. These can be downloaded from Google Play, installed on your tablet, then access your DLNA server to stream video or music. The DLNA server can be any PC on the network that has shared media files.
Once you set up a wireless connection between tablet and TV, you are free to move about as long as you maintain a wireless connection.
If you are not successful getting a wireless connection established between your Android device and TV, a good option is to make the connection using an HDMI cable. Connect Android to TV Using HDMI
