How to Change Input source on Samsung Smart TV

Changing the input source on a Samsung Smart TV is essential when you want to switch from live TV to a connected device like a gaming console, set-top box, or a media player. Although the process is simple, it can vary slightly depending on the TV model or the type of remote you’re using. In this guide, I’ll walk you through multiple methods to switch inputs based on personal experience, real-world user feedback, and tested troubleshooting.

Why Changing Input Source Matters

Modern smart TVs support multiple inputs such as HDMI, AV, USB, PC, and screen mirroring. If you connect a PlayStation, Amazon Fire Stick, or laptop via HDMI, the TV won’t auto-switch unless the right source is selected manually.

I’ve had to explain this to friends and relatives countless times when they assumed plugging in a cable is enough. This article ensures that no matter which Samsung Smart TV model or method you use, you’ll always know how to change input sources.

Method 1: Using the Samsung Smart Remote (One Remote)

If your TV came with the latest Samsung One Remote, here’s what to do:

Step-by-Step:

1. Power on the TV.
   • Use the power button on the remote or side panel.
2. Press the Home Button.
   • This opens the Smart Hub main screen.
3. Scroll to the Left and Select “Source.”
   • This appears on the home menu bar. Use the arrow keys to navigate.
4. View Available Inputs.
   • You’ll see options like HDMI1, HDMI2, AV, etc., along with device icons.
5. Select Desired Input.
   • Use the arrow keys to highlight your input source (e.g., HDMI1 for PS5).
   • Press OK/Enter to switch.
6. Confirm the Device is Active.
   • Ensure the connected device is powered on; otherwise, the source may appear unavailable.

Tip: You can rename HDMI sources by pressing Up on the input tile and selecting “Edit”.

Method 2: Using a Standard Samsung TV Remote (With Source Button)

If your TV has a traditional Samsung remote with a dedicated Source button (usually labeled or symbolized by an arrow and box), follow these steps.

Step-by-Step:

1. Press the “Source” Button.
   • The input source menu will pop up immediately on the screen.
2. Use Arrow Keys to Navigate.
   • Select the desired input (e.g., HDMI2).
3. Press “Enter” to Confirm.
   • The TV screen will now show content from the selected input.

This is often the fastest method for older models.

Method 3: Using TV Buttons (If Remote is Lost)

In cases where the remote is missing, the TV’s physical control button helps.

Step-by-Step:

1. Locate the Control Button.
   • Usually found under the TV panel (middle or side).
   • It may be a joystick-style button or a small set of physical buttons.
2. Press the Button to Open the Menu.
3. Navigate to “Source.”
   • Use short presses or joystick movements to scroll.
4. Select Your Desired Input.
   • Press or hold the button to confirm.

Note: The TV control buttons provide limited navigation but are good in emergencies.

Method 4: Using the SmartThings App (No Remote Needed)

You can control most Samsung Smart TVs via the SmartThings app, available for Android and iOS.

Step-by-Step:

1. Install and Open SmartThings.
2. Add Your Samsung TV.
   • Ensure the TV and phone are on the same Wi-Fi network.
   • The app will detect your TV automatically.
3. Select the TV and Tap “Remote.”
4. Access the Input Option.
   • Look for the “Source” icon in the remote interface.
5. Choose the Input You Want.
   • Tap to switch between HDMI, AV, or other options.

This method is ideal when the physical remote isn’t available or you prefer phone control.

Method 5: Using Voice Control (With Bixby, Alexa, or Google Assistant)

If your Samsung TV supports voice assistants, you can switch inputs by speaking.

Step-by-Step:

1. Press and Hold the Microphone Button.
   • This is on your One Remote.
2. Say a Command Like:
   • “Switch to HDMI1”
   • “Change source to AV”
3. TV Will Confirm the Action.

For Alexa or Google Assistant, ensure the TV is linked through the SmartThings or Google Home app.

Bonus: Rename and Add Inputs to Home Screen

To make switching easier:

Renaming:

1. Go to Source > Highlight an input.
2. Press Up, then Edit.
3. Enter a custom name like “Xbox” or “Cable Box.”

Adding to Home:

1. Select the input and press Down.
2. Choose Add to Home.

This pins your most-used input to the Smart Hub for one-click access.

Troubleshooting Tips

• Source Not Detected?
  • Make sure the external device is powered on and cables are connected properly.
• Source Grayed Out?
  • Some TVs only enable sources when a live signal is detected.
• Input Missing After Firmware Update?
  • Try rebooting the TV and doing a fresh connection.

Final Thoughts

Changing the input source on a Samsung Smart TV is easy once you understand the layout and options available. Whether you’re using a standard remote, One Remote, physical buttons, or SmartThings, Samsung has made the process accessible across all models.

From my personal use over the years, I recommend renaming and pinning your most-used inputs to streamline access, especially for those who switch between gaming consoles, laptops, and streaming boxes frequently.

Invest a few minutes to set it up once — and you’ll save time every day.

If your input sources still don’t work properly after trying all these methods, it may be worth checking your HDMI cable or having the TV checked for port issues.
