Find and press the HDMI button on your Samsung remote

The fastest way to change HDMI inputs on a Samsung TV is to use the remote control. Look for a button labeled HDMI on your remote — it is usually near the top or middle section, sometimes grouped with other input buttons. Press it once.

When you press HDMI, your TV will display a small menu showing all available HDMI ports (usually labeled HDMI 1, HDMI 2, HDMI 3, and HDMI 4). The port currently in use will be highlighted or marked as active. This menu typically stays on screen for a few seconds before disappearing.

Select the HDMI port where your device is connected

Use the arrow buttons on your remote to highlight the HDMI port you want to switch to. If you are connecting a cable box, use the port where you plugged in the HDMI cable. If you are connecting a gaming console or streaming device, select the matching port number.

Once you have highlighted the correct port, press the Enter or OK button (usually in the center of the arrow pad) to confirm your selection. Your TV will when ready switch to that input and display whatever is connected to that port.

Key Takeaways

  • Press the HDMI button on your Samsung remote to see all available ports and switch between them.
  • Use the arrow buttons to highlight the port number matching where your device is plugged in, then press Enter.
  • If your remote does not have an HDMI button, you can access inputs through the TV menu using the Home button.
  • Check that the HDMI cable is fully inserted into both the TV port and your device before switching inputs.
  • Samsung TVs remember which input you last used, so you may need to switch back if the TV defaults to a different port.

Use the Home menu if your remote has no HDMI button

Older Samsung remotes or replacement remotes may not have a dedicated HDMI button. If yours does not, press the Home button (usually at the top of the remote) to open the main menu on your TV screen.

Navigate to Settings or Input using the arrow buttons, then look for an option called Input Source, HDMI, or External Device Manager. The exact name varies by TV model and software version. Highlight your desired HDMI port and press Enter to switch to it.

Check the physical HDMI ports on the back of your TV

Before switching inputs, confirm that your device is actually plugged into an HDMI port on your Samsung TV. The ports are on the back or side of the TV and are labeled HDMI 1, HDMI 2, HDMI 3, or HDMI 4. The label is usually printed directly on the TV body next to each port.

Make sure the HDMI cable is pushed in completely — a loose connection will not register, and your TV will not detect the device. If the cable feels loose, unplug it and reinsert it firmly until you hear or feel a click. Then try switching to that input again using your remote.

Restart your TV if a device does not appear after switching inputs

If you switch to an HDMI port but see a black screen or a "No Signal" message, the device may not be powered on or the cable may not be fully connected. First, check that the device (cable box, gaming console, streaming device) is turned on and has power.

Next, unplug the HDMI cable from both the TV and the device, wait 10 seconds, and plug it back in firmly. If the problem persists, turn off your TV completely using the power button on the remote or the TV itself, wait 30 seconds, and turn it back on. Then switch to the correct HDMI input again. This straightforward restart often fixes connection issues that prevent the TV from recognizing the device.

Know which HDMI port to use for different devices

Samsung TVs treat all HDMI ports the same way — any port will work with any HDMI device. However, some devices work better on certain ports. If you have multiple devices connected at once, assign each one to a different port so you can easily switch between them without unplugging cables.

For example, you might use HDMI 1 for your cable box, HDMI 2 for a gaming console, and HDMI 3 for a streaming device. Write down which device is on which port and keep a note near your TV. This makes it much faster to find the right input when you want to switch devices, and it prevents confusion if someone else in your household is using the TV.

Frequently Asked Questions

Why does my TV show "No Signal" when I switch to an HDMI port?

The device connected to that port is either powered off or the cable is not fully inserted. Turn on the device first, then check that the HDMI cable is pushed all the way into both the TV port and the device. If it is still not working, unplug the cable, wait 10 seconds, and plug it back in firmly.

Can I use any HDMI port on my Samsung TV?

Yes, all HDMI ports on a Samsung TV work the same way and will accept any HDMI device. You can use any port for any device — cable boxes, gaming consoles, streaming devices, and computers all work on any HDMI input.

My remote does not have an HDMI button. How do I switch inputs?

Press the Home button to open the main menu, then navigate to Settings or Input Source. Look for an option to select your HDMI port and press Enter. The exact menu name varies by TV model, but the process is the same on all Samsung TVs.

How do I know which HDMI port my device is plugged into?

Look at the back or side of your TV where the HDMI cables are connected. Each port is labeled with a number (1, 2, 3, or 4). The label is printed on the TV body right next to the port. Match the cable to the label to find the correct port number.

Can I switch HDMI inputs without a remote?

Yes. Most Samsung TVs have physical buttons on the side or bottom of the TV. Look for buttons labeled with arrows or an input/source button. Use these to navigate the on-screen menu and select your HDMI port, though it is slower than using the remote.
