How to Switch HDMI Inputs on Your Samsung TV

Finding and Using the HDMI Input Button

To switch HDMI inputs on a Samsung TV, press the Input button on your remote control. This button is usually near the top or middle of the remote, sometimes labeled as "Input," "Source," or with a rectangle-and-arrow symbol. A menu will appear on your screen showing all available inputs — HDMI 1, HDMI 2, HDMI 3, HDMI 4, and any other connected devices.

Once the input menu is open, use the arrow buttons on your remote to highlight the HDMI port you want to use, then press Enter or Select. Your TV will switch to that input when ready. If you have multiple devices connected — a cable box, gaming console, streaming device, or soundbar — each one typically plugs into its own HDMI port on the back of the TV.

If you cannot find the Input button on your remote, look for a button labeled "Source" instead — Samsung uses both names depending on the remote model and TV age. Some older Samsung remotes have a dedicated physical button; newer ones may require you to swipe or tap a virtual button on a touchpad remote.

Key Takeaways

Press the Input or Source button on your Samsung remote to open the input menu.
Use the arrow buttons to select which HDMI port you want to view, then press Enter.
Your TV will switch to the selected input within one or two seconds.
If your remote has no Input button, check the TV's physical buttons on the side or bottom bezel.
You can label each HDMI input in your TV settings so you remember which device is plugged into which port.

Using the TV's Physical Buttons If Your Remote Is Lost

If your remote is missing or the batteries are dead, you can still switch inputs using the buttons on the TV itself. Look for buttons on the bottom bezel or the side edge of your Samsung TV — usually a row of touch-sensitive buttons or physical buttons labeled with symbols.

Press the button that looks like a rectangle with an arrow, or the button labeled "Menu" or "Input." This will open the same input menu you see with the remote. Use the adjacent arrow buttons to navigate to your desired HDMI input and press the center button to select it. The process is slower than using the remote, but it works the same way.

If your TV has no visible buttons, consult your TV's manual or look at the bottom and sides of the frame carefully — some Samsung models have recessed buttons that are straightforward to miss. You can also order a replacement Samsung remote online if the physical buttons are not accessible.

Labeling Your HDMI Inputs for Easier Switching

Samsung TVs allow you to rename each HDMI input so you know at a glance which device is connected to which port. This is especially useful if you have four or more devices plugged in. To do this, open the input menu by pressing Input, then look for an option to edit or rename the input — this is usually shown as a pencil icon or an "Edit" button.

Select the HDMI input you want to rename, then use the remote's keyboard or on-screen keyboard to type a name like "PlayStation," "Cable Box," "Roku," or "Soundbar." Save the name, and it will appear in the input menu from that point forward. This saves you from having to remember which physical port corresponds to which device.

Not all Samsung TV models have this feature, particularly older ones. If you do not see an edit option in your input menu, your TV model may not support custom input names. In that case, you can write the device names on a piece of tape and stick it next to the HDMI ports on the back of the TV as a reference.

What to Do If an HDMI Input Is Not Showing Up

If you plug in a device but its HDMI input does not appear in the menu, the first step is to check that the cable is fully inserted into both the TV and the device. HDMI cables can look connected but still be slightly loose. Unplug the cable from both ends, wait five seconds, and plug it back in firmly until you hear or feel a click.

If the input still does not appear, try a different HDMI port on the TV. Some ports can fail over time, especially if the TV is old or has been moved frequently. If the device works in a different port, the original port may be damaged and will need professional repair.

If none of the HDMI ports show the device, the problem may be with the cable itself or the device's HDMI output. Try a different HDMI cable if you have one available. If the device works with a different cable, replace the original one. If it does not work with any cable or port, the device's HDMI output may be faulty.

Switching Inputs Automatically When a Device Turns On

Many Samsung TVs have a feature called HDMI-CEC (Consumer Electronics Control) that automatically switches to the correct input when you turn on a connected device. For example, if you turn on your PlayStation, the TV may switch to HDMI 3 on its own without you pressing the Input button.

This feature is usually turned on by default, but you can control it through your TV's settings. Go to Settings, then look for a menu called "External Device Manager," "HDMI-CEC," or "Anynet+" (Samsung's name for HDMI-CEC). You can turn the feature on or off, or disable it for specific devices if it is switching inputs when you do not want it to.

If your TV is not switching automatically and you want it to, check that HDMI-CEC is enabled in settings and that your device supports it. Not all devices have HDMI-CEC — older devices and some budget models do not. If your device does not support it, you will need to switch inputs manually each time.

Troubleshooting a Stuck or Unresponsive Input Menu

If the input menu opens but will not respond to your remote buttons, or if it freezes on one input, try unplugging the TV from the wall outlet for 30 seconds, then plugging it back in. This resets the TV's processor and often clears temporary glitches that prevent the input menu from working.

If the menu still does not respond after a restart, check that your remote batteries are fresh and that you are pointing the remote directly at the TV. Some Samsung remotes require a clear line of sight to the TV's infrared receiver. If the remote works for other functions but not the input menu, the remote may need new batteries or the TV may have a software issue.

As a last resort, you can perform a factory reset of your TV through the Settings menu, but this will erase any custom input names and other preferences you have set. Only do this if the input menu remains unresponsive after restarting and replacing remote batteries.

Understanding HDMI Port Differences on Your Samsung TV

Most Samsung TVs have four HDMI ports on the back, labeled HDMI 1, HDMI 2, HDMI 3, and HDMI 4. All four ports work the same way for standard devices like cable boxes, gaming consoles, and streaming devices. However, some newer Samsung TVs mark one or two ports as "HDMI eARC" or "HDMI ARC," which have an additional feature for audio.

The eARC port allows your TV to send audio back to a soundbar or receiver without needing a separate audio cable. If you have a soundbar, connecting it to the eARC port (usually HDMI 3 or HDMI 4) simplifies your setup. For regular devices that do not need this feature, any HDMI port works equally well.

Older Samsung TVs may have only two or three HDMI ports. If you have more devices than ports, you can use an HDMI splitter or switch box, which plugs into one HDMI port and allows you to connect multiple devices. However, you will still need to manually switch between devices using the splitter's own controls.

Frequently Asked Questions

Why does my TV keep switching back to the last input I was watching?

Your TV may have a feature that remembers the last input you used and returns to it when you turn the TV back on. This is usually controlled in Settings under "External Device Manager" or "HDMI-CEC." You can turn this behavior off if you prefer the TV to always start on a specific input like your cable box.

Can I set a default input so the TV always starts on the same channel?

Some Samsung TV models allow you to set a default input in Settings, but not all do. Look in Settings under "External Device Manager" or "General" for an option to set the startup input. If your model does not have this option, the TV will remember whichever input you were last watching and return to it when powered on.

What if I have two devices on the same HDMI input?

Each device needs its own HDMI port. You cannot plug two devices into the same HDMI input at the same time — only one will work. If you have more devices than ports, you will need an HDMI switch box that lets you connect multiple devices and switch between them using a separate control.

Does switching HDMI inputs damage the TV or cables?

No, switching inputs does not damage your TV or cables. You can switch between inputs as many times as you want without any risk of harm. The only wear comes from repeatedly plugging and unplugging cables, so avoid that if possible.

Why is there no picture on one of my HDMI inputs?

Check that the cable is fully inserted and the connected device is turned on. If the device is on and the cable is find, try that device in a different HDMI port to see if the original port is faulty. You can also try a different HDMI cable to rule out a bad cable.
