Understanding Input Sources on LG Smart TVs

Input Sources on LG Smart TVs

An input source on your LG TV refers to the external device sending a signal to the TV such as a cable box, Blu-ray player, gaming console, streaming media stick, laptop, and more. Basically, anything plugged into your TV’s HDMI ports that you want to view or play content from.

Here are some of the most common input sources people connect:

  • Cable or satellite box

  • Blu-ray or DVD player
  • Gaming consoles like Xbox and PlayStation

  • Streaming devices like Roku or Amazon Fire Stick
  • External speakers or sound system
  • Computer or laptop
  • And more!

Having multiple devices connected is why you need to be able to easily switch between different input sources.

Preparing Your Devices Before Changing Inputs

Before attempting to change inputs on your LG smart TV, it’s important to first make sure all your external devices you want to use are powered on and properly connected to the TV.

Here are some tips for avoiding headaches:

  • Check that devices are plugged into the correct HDMI input ports on the TV.
  • Confirm external devices like game consoles are turned on.
  • Ensure power cables and HDMI cables are securely inserted at both ends.
  • Try a different HDMI cable if issues persist, in case of a faulty cable.
  • For streaming sticks and computers, ensure WiFi is enabled to allow casting or screen sharing to the TV.

Taking this quick peek at your connections will prevent the frustration of no signal displaying when trying to view a new input source.

Accessing the Input Menu on Your LG Smart TV

The input menu on your LG smart TV is where you actually change the input source. There are a couple ways to access this:

  1. Use the ‘Input’ or ‘Source’ button on your LG remote. This takes you directly to the input menu.
  2. Access it from the settings menu:
    • Use remote and select the cog icon from the top row of main menu options to enter settings.
    • Navigate to “Connection” or “Devices” and select “Input List” or “Edit Input Labels”

Either way, this brings up the list of connected devices and inputs to switch between.

Tip: With some LG TVs you can also press the icon button on an LG Magic Remote to prompt the TV to display currently active input and connected devices.

Selecting the Desired Input Source

From within the Input List menu, simply use the arrow buttons and ‘OK/Enter’ button on your LG TV remote to choose the input source you want to switch to.

The TV displays a list of options like:

  • HDMI 1
  • HDMI 2
  • Cable Box
  • Blu-ray Player
  • Game Console

And more depending on your specific devices connected.

You’ll then see the picture change as it swaps over to the selected input.

Pro Tip: You can rename the inputs to match your connected device so it’s clearer which is which. For example labeling one connection as “Roku” rather than just “HDMI 3”.

Using Quick Access Input Changes

For inputs you switch to often like game consoles or streaming sticks, there’s even faster ways to change sources that skip having to dig through the settings menu each time:

  • Device Specific LG Remote Buttons: Many LG remotes have quick access buttons built-in to instantly pull up certain inputs like cable box or HDMI. Just press button to switch over.
  • Quick Access Menu: Bring up this menu by long pressing number button ‘0’ on LG’s Magic Remote. This also displays connected inputs for 1-click changes.
  • LG ThinQ Mobile App: Use LG’s iPhone/Android app as a remote to swiftly select favorite input sources.

So there you have it! With just your LG television remote, changing inputs is a breeze. Now enjoy seamlessly switching between all your entertainment devices.
