How to Connect Laptop to TV With HDMI Cable

Connecting your Windows or Mac laptop to your TV via HDMI is fairly straightforward and should hopefully only take a few minutes to complete.

How to Switch From Mirroring to Extending

The default setting for a laptop to TV HDMI connection is to have your laptop’s screen be mirrored on the television. This basically just means that whatever you see on your laptop’s screen will be shown on your TV’s screen simultaneously. An alternative setting is to have your TV act as a kind of extension or second screen which you can control from your laptop. This can allow you to open files or apps privately on your laptop and show select media to others on the TV screen. To make this change on a Mac, open the Apple menu in the top-left corner and click System Preferences > Displays > Arrangement. To switch from Mirror to Extend on a Windows 10 laptop, open the Action Center by clicking on the square icon in the lower-right corner or by swiping in from the right side of the screen on a touch-enabled device such as a Surface Pro. Click Project to view your TV display options. You can change your display preferences as often as you like.

Do You Need an HDMI Adaptor?

If your laptop doesn’t have an HDMI port, and most don’t, you’ll need to use an HDMI adaptor. Your laptop may have actually come with one when you got it but you don’t need to worry if it didn’t as HDMI adaptors are relatively cheap and are very easy to find in both online and traditional electronic stores. The following port types can be used to connect a laptop to a TV via HDMI with an appropriate adaptor:

Mini-HDMI Micro-HDMI USB-C Thunderbolt DisplayPort Mini DisplayPort

Laptop-to-TV HDMI Troubleshooting

Having trouble getting the image or sound to play through your TV from your laptop? Here are some quick solutions worth trying.

Restart your laptop: Sometimes restarting your laptop with the HDMI cable connected can force its display to switch to the TV screen. Check the HDMI port on your TV: HDMI ports on TVs can often be very tight and it’s easy to think that the cable has been plugged in when in fact the connection is barely being made. Firmly and carefully check to make sure that the cable is plugged in as far as it will go. Check the HDMI port on your laptop: Some laptops, such as some Surface Pro models, have curved edges which can make the HDMI adaptors disconnect. Make sure all the edges of the port are sealed and that the cable isn’t being pulled out. Check the HDMI cable for damage: It’s possible that your HDMI cable may have been damaged while being stored or moved. Install the latest operating system and firmware updates: Whether you own a Mac or a Windows laptop, downloading the latest updates can often fix a lot of tech issues. Double-check the HDMI source: Your TV may be trying to read from the wrong HDMI port. Browse through all of your media sources on your TV with your remote. Switch HDMI ports: If you think an HDMI port may be damaged, try using a port that’s proven to work such as the one connected to your Xbox or Blu-ray player.
