Input sources on your LG television refer to the different devices and connections you can use to display content on your screen. When you have multiple devices connected to your TV—such as a cable box, streaming device, gaming console, or computer—each one uses a different input port. Your LG TV contains several of these ports, typically located on the back or side of the unit. Learning about these different inputs helps you understand how your TV receives signal from various devices and why you need to switch between them.

Most LG televisions have multiple HDMI ports, which are the standard connection type for modern devices. Depending on your TV model, you might have two to four HDMI inputs available. Additionally, many LG TVs include other connection options like composite video inputs (the older red, white, and yellow cables), component video inputs, or optical audio outputs. Some newer LG models also feature smart TV functionality built-in, which creates another "input" option that doesn't require an external device.
The reason understanding inputs matters relates to how your TV operates. When you power on your television, it displays whatever input source was last used. If you want to watch your cable box but your TV defaults to an HDMI input where nothing is connected, you'll see a blank or "no signal" screen. This is why learning to navigate between inputs is a practical skill for getting the most from your television viewing experience.
LG TVs typically label their inputs numerically or descriptively. You might see labels like "HDMI 1," "HDMI 2," "Video 1," or names like "Cable Box" if you've customized the input labels on your TV. The physical ports on your television usually have these labels printed directly beside or above them, helping you identify which device connects to which port.
Practical takeaway: Spend a few minutes examining the back and sides of your LG TV to identify all available input ports. Write down which devices are connected to which inputs so you have a reference guide for switching between them.
The most common method for switching input sources on an LG TV involves using your remote control. Most LG televisions come with a standard remote that includes an "Input" button, though its location varies depending on the remote model and TV age. On many LG remotes, this button appears near the top of the device and is labeled either "Input," "Source," or "TV/Video." Some older LG remotes might have the input function combined with other buttons.

To switch input sources using your remote, first locate the Input or Source button. Press this button once, and your TV screen should display an on-screen menu showing all available inputs. This menu typically appears as a list on the left side of your screen or as a horizontal bar across the bottom, depending on your LG TV model. The menu will show which input is currently selected, usually highlighted in a different color or with a different text style.
Once the input menu appears on your screen, you can navigate through the available options using the arrow buttons on your remote. Move up or down (or left and right, depending on menu orientation) to highlight the input you want to use. For example, if you want to switch from your cable box to your streaming device, you'd highlight whichever HDMI input your streaming device connects to. After highlighting your desired input, press the "Enter" or "OK" button on your remote to confirm your selection.
Different LG TV models display this menu slightly differently. Some newer models show input options with small preview windows displaying what's currently on each connected device, while older models show only text labels. Regardless of the visual presentation, the basic process remains the same: locate the Input button, navigate to your desired input, and press Enter to switch to it.
If your remote is lost or not functioning properly, you should know that most LG remotes follow a similar button layout. The Input button is typically located in the upper portion of the remote, separate from the volume and channel controls. If you're using a universal remote or a replacement remote, look for an Input or Source button in a similar location.
Practical takeaway: Locate the Input button on your LG remote right now and practice pressing it to see your TV's input menu. This familiarity means you'll quickly know how to switch inputs whenever you need to.
When you press the Input button on your remote, your LG TV displays a visual menu showing all connected input options. Understanding what you're seeing on this menu helps you make faster selections. The menu layout depends on your TV model and software version, but most LG televisions use one of two standard formats: a sidebar menu on the left or a horizontal menu bar at the bottom of the screen.

In the sidebar format, which appears on many LG models, you'll see a vertical list of input options displayed on the left portion of your screen. Each input appears as a selectable item, often with a small icon next to it indicating the type of connection. For instance, an HDMI input might show a small display icon, while an antenna input might show an antenna symbol. The currently active input typically appears highlighted in white text, while inactive inputs appear in gray text. Above each input, you might see a label you've customized (like "Cable Box" or "PlayStation"), or you might see the default label (like "HDMI 1" or "HDMI 2").
In the horizontal menu format, which appears on some newer LG TV models, the input options display as a list running across the bottom of your screen. You navigate through these options using the left and right arrow buttons instead of up and down. This format often includes small thumbnail previews of what's currently displaying on each input, allowing you to see which device has active content without switching to it first.
While the input menu is displayed, you should notice that your TV continues to display the current content in the background. This allows you to see what's playing on your current input while you're selecting a new one. Some newer LG models allow you to see previews of multiple inputs simultaneously, showing you what's on several devices at once in small windows within the menu.
The input menu remains visible on your screen until you make a selection or press a button to close it. If you want to close the menu without switching inputs, you can typically press the "Exit" button on your remote or wait several seconds for the menu to disappear automatically.
Practical takeaway: Next time you use your TV, take note of whether your input menu appears vertically or horizontally, and observe the icons used to represent different input types. This visual familiarity speeds up your future input selections.
LG televisions offer the option to customize input labels, which can make switching between sources significantly faster and more intuitive. Instead of referring to inputs by their technical names like "HDMI 1" or "HDMI 2," you can rename them to reflect what's actually connected—such as "Cable Box," "PlayStation," "Apple TV," or "Computer." This customization is particularly useful if you have multiple HDMI-connected devices and want to avoid confusion when selecting inputs.

To customize input labels on your LG TV, you'll need to access your TV's settings menu. Start by pressing the "Settings" button on your remote, or look for a gear icon in your TV's main menu. From the settings menu, navigate to an option typically labeled "Inputs," "Input Settings," or "Device Name Settings." The exact location varies by LG model and software version, but this option is usually found in the main settings area rather than buried in advanced options.
Once you've located the input settings, your TV will display a list of all available inputs. Select the input you want to rename, and your TV will prompt you to enter a new name. You'll use your remote's arrow buttons and number pad to type in a custom name. Most LG TVs allow you to enter names between 5 and 12 characters long, so you have flexibility in how descriptive you want to be. After entering your preferred name, confirm the change, and your TV will save this customization.
When you've customized your input labels, these custom names appear in your input selection menu from that point forward. This means every time you press the Input button, you'll see "Cable Box" instead of "HDMI 1," or "Gaming Console" instead of "HDMI 3." This makes the input selection process more intuitive, especially for household members who may not be familiar
