If your TV has an HDMI cable port, you should be able to connect you laptop, phone or tablet. One end of the HDMI cable will connect to your TV and the other will connect to your device – you’ll need to make sure you have the correct HDMI cable compatible with the device you’re using.
If you’re using a phone or tablet it’s likely that this will connect to the same socket you use to charge your phone. If you’re using a laptop you’ll see that it will have slots along the side of the keyboard and if you’re using a computer, you’ll either connect to a slot along the side of your monitor (screen) or in the computer itself.
Once you have the right cable and your device is connected to your TV (we’d recommend connecting to HDMI port 1), it will either automatically begin sharing your screen or you will need to access your TV’s menu using your remote control to change the source or input to HDMI – this will correspond to the HDMI slot you’ve connected to on your TV and there may be more than one to choose from.
