Viewing your phone, tablet or laptop on a larger TV screen is usually called screen mirroring or screen casting. Most Samsung smartphones or tablets incorporate a feature that you can use to connect. Depending on the model of your phone, this will either be called Screen Mirroring, Smart View or Quick Connect. You will be able to find these in Settings or in the pull down menu. If your device does not support screen mirroring with your TV, you can try using a third-party app to enable your device to connect to your TV. you can try using an HDMI cable, or you can buy a streaming device such as an Amazon Firestick, or Google Chromecast. Check out Miracast, which lets you stream your stuff with your home Wi-Fi. It's compatible with Windows Phone and Androids with 4.2 Jelly Bean or later, although not all Android devices can mirror your mobile screen via Miracast. Newer phones like the LG G5 can do the job.
