The quickest way to change HDMI inputs on a Samsung TV

Press the Input button on your Samsung remote — it is usually near the top or middle of the remote, sometimes labeled Source. A menu will appear on your screen showing all available inputs. Use the arrow buttons to highlight the HDMI port you want, then press Enter or OK. Your TV will switch to that input immediately.

If you cannot find the Input button on your remote, you can also access inputs through the TV menu itself. Press the Menu button, navigate to Input or Source, and select the HDMI port from the list that appears.

Most Samsung TVs label their HDMI ports as HDMI 1, HDMI 2, HDMI 3, and HDMI 4 on the back or side of the set. The menu will show you which devices are connected to each port, making it easier to find the one you need.

Key Takeaways

  • The Input or Source button on your remote is the fastest way to switch between HDMI ports without touching your TV.
  • Samsung TVs display connected devices in the input menu, so you can see at a glance which device is on which HDMI port.
  • If your remote does not have an Input button, you can reach the same menu through the TV's main menu system.
  • Most Samsung TVs have four HDMI ports, and you can connect different devices to each one without unplugging anything.

Where the HDMI ports are located on your TV

Samsung TVs have HDMI ports on the back or on the side panel, depending on the model and year. Look for a row of ports labeled HDMI 1, HDMI 2, HDMI 3, and HDMI 4. The exact location varies — some models have all ports on the back, while others have one or two on the side for easier access.

Check your TV's manual or the Samsung support website for your specific model number if you are having trouble locating the ports. The model number is usually printed on a sticker on the back of the TV or in the Settings menu under About This TV.

Using the remote to switch inputs without a dedicated Input button

If your Samsung remote does not have a dedicated Input button, you can still change HDMI ports through the menu. Press Menu on your remote, then look for an option labeled Input, Source, or HDMI. The exact wording depends on your TV model and remote type.

Once you open the input menu, use the arrow buttons to move between options and press Enter to select. The TV will switch to your chosen input and the menu will close automatically.

What to do if your TV is not responding to input changes

If pressing the Input button does not open the menu, the remote batteries may be dead or the remote may not be paired with your TV. Replace the batteries in your remote with fresh ones and try again. Make sure you are pointing the remote directly at the TV's sensor, usually located on the front panel below the screen.

If the menu still does not appear, try unplugging your TV from the wall outlet for 30 seconds, then plugging it back in. This resets the TV's system and often fixes unresponsive controls. Once the TV restarts, try the Input button again.

If you have a newer Samsung TV, you may also have a SmartThings app on your phone that can control the TV. Open the app, select your TV, and look for an input or source option in the remote control interface.

Switching inputs on Samsung Smart TVs with voice control

If your Samsung TV has a built-in voice assistant or is connected to Alexa or Google Assistant, you can change inputs by voice. Say "Switch to HDMI 2" or "Change input to HDMI 3" and the TV will respond. The exact phrasing depends on which voice assistant your TV uses.

To set up voice control, go to Settings on your TV, find Voice or Voice Assistant, and follow the setup steps. You will need to connect your TV to Wi-Fi and link it to your voice assistant account.

Labeling your HDMI ports so you remember what is plugged in

Samsung TVs let you rename HDMI inputs so the menu shows custom names instead of just "HDMI 1" or "HDMI 2". This is useful if you have multiple devices connected — you can label them as "PlayStation," "Cable Box," "Streaming Device," or whatever makes sense for your setup.

To rename an input, press the Input button to open the input menu, highlight the port you want to rename, and look for an edit or rename option. Not all Samsung models support this feature, but most newer TVs do. Check your TV's manual if you cannot find the rename option.

Frequently Asked Questions

Why does my TV keep switching back to the previous input?

This usually happens if your TV is set to automatically return to a default input after a certain time, or if a connected device is sending a signal that overrides your choice. Check Settings > General > External Device Manager and turn off any auto-switching features. If a device like a cable box keeps taking over, unplug it briefly and try again.

Can I use a different remote to change HDMI inputs?

Most universal remotes can control Samsung TV inputs if they are programmed correctly. You will need the TV's model number to set up the remote. Follow the universal remote's instructions to enter the Samsung code, then test the Input button. Some universal remotes may not support all Samsung models, so check the remote's compatibility list first.

What if I plug something into an HDMI port and it does not show up in the input menu?

Make sure the device is powered on and the cable is fully inserted into both the TV and the device. Try a different HDMI cable — some cables are faulty or damaged. If the device still does not appear, try plugging it into a different HDMI port. If it works in another port, the original port may be damaged and you should contact Samsung support.

Is there a way to set a default HDMI input so the TV opens to it automatically?

Some Samsung TVs allow you to set a default input in the settings menu. Go to Settings > General > External Device Manager and look for an option to set a startup input. Not all models support this, so check your TV's manual if you cannot find it.
