➤ How to connect LG Smart TV to computer 🕹

To play or use a larger screen, you can connect LG Smart TV to computer. You can watch videos or listen to music using the built-in SmartShare option or you can view your computer screen on your TV with Miracast (wireless) or via HDMI (wired) connection.

How to connect LG Smart TV to computer via HDMI cable

Make sure your computer has an HDMI port. The HDMI ports seem thin and with wide slits whose base is narrower than the top. Most modern computers have at least one free HDMI port.
Buy an adapter if needed, if your computer doesn't have an HDMI port, you will need to buy an HDMI output adapter (the output is your computer's video output). Common non-HDMI outputs are DisplayPort, USB-C, and DVI or VGA (older computers only).
Buy a cable that is long enough, measure the space between your TV and computer (if you don't use a laptop), and then buy an HDMI cable that is a little longer than at least one meter. This will prevent you from running out of cable if you move either the TV or the computer.
There is little difference between an HDMI cable for 5 euros and another for 70 euros. Because HDMI is a digital signal, it is either "on" or "off" and the cable does not affect the quality of the signal. The difference in quality will only be noticeable with longer cables.
HDMI cables comply with standards up to 12m in length. There are longer cables that technically still work, but probably don't meet the standards.
If you have to use an HDMI cable over very long distances, you will need an amplifier to boost the signal.
Plug one end of the HDMI cable into the TV. The HDMI cable must be plugged into one of the HDMI inputs on the back (or sides) of the TV.
If your LG TV has more than one HDMI port, you will see a number next to the ports. This number refers to the channel you will need to select next.
Plug the other end of the HDMI cable into your computer. Connect the HDMI cable to the computer's HDMI port.
If you are using a computer video output adapter, connect the adapter to the computer and then the HDMI cable to the HDMI port on the other side of the adapter.
Turn on your LG TV. Press the power button on the remote control of your LG TV.
Select the HDMI input. Use the “Enter” button on the TV to select the HDMI port number where the HDMI cable is connected. You will need to see your computer screen appear on the TV. Select your LG TV as the audio output. If the sound is coming from your computer speakers and not your TV, do the following:
open the Start menu
write audio
click on the speaker-shaped option
select your LG TV in the Playback tab
click on Default
select Apply then OK.

Use your LG TV as an extension of your computer. You will need to be able to see your computer screen on your LG TV. It means you can watch online content or watch movies from your library while using your computer as a remote control.
