You can plug your laptop or mobile device into your TV using an HDMI cable. Usually, HDMI ports are found at the back of your TV.
Attach your cable to this socket, and plug the other end into the device you intend to stream with. You will need to make sure you have the right cable for your TV and devices, and if you are using a mobile or tablet, you might need an adaptor also.
Now that you have connected your cable, you may need to change your TV’s input settings. Use your remote control to find the source menu, and select the channel associated with the socket your device is plugged into. You may also need to change the sound settings on your device to ensure it is using the TV to project the sound.
