How to Switch HDMI Inputs on Your Samsung TV

The fastest way to change HDMI on your Samsung TV

Press the Input or Source button on your Samsung remote. A menu will appear on screen showing all available inputs — HDMI 1, HDMI 2, HDMI 3, HDMI 4, and any other connected ports. Use the arrow buttons to highlight the HDMI port you want, then press Enter or Select. Your TV will switch to that input when ready.

If you cannot find the Input button on your remote, look for a button labeled Source instead — Samsung remotes use both terms depending on the model and year. The button is usually near the top or middle of the remote, often grouped with other control buttons.

Some Samsung remotes have a dedicated HDMI button that takes you directly to HDMI inputs without showing all ports. If your remote has one, pressing it will cycle through your HDMI ports one at a time.

Key Takeaways

The Input or Source button on your remote opens a menu showing all connected HDMI ports and other inputs.
Use arrow keys to select the HDMI port you need, then press Enter to switch to it.
If your remote has a dedicated HDMI button, pressing it cycles through HDMI ports without opening the full input menu.
You can also change inputs using your TV's physical buttons if you cannot locate your remote.
Samsung TVs remember which input you last used, so switching back to a frequently used port takes only one or two button presses.

Using the physical buttons on your Samsung TV

If your remote is lost or not working, you can change HDMI inputs using the buttons on the TV itself. Look for buttons on the bottom or side of your Samsung TV — usually labeled with symbols or text. Press the button labeled Menu, Input, or Source depending on your model.

Once the input menu appears on screen, use the arrow buttons on the TV to navigate to your desired HDMI port. Press the center button or the button marked Select to confirm your choice. The TV will switch to that input.

Physical buttons vary by Samsung TV model and year. Newer models often have touch-sensitive buttons along the bottom bezel, while older models have raised buttons on the side or back. Check your TV's manual or the manufacturer's website if you cannot locate the input button on your specific model.

What to do if the HDMI port is not showing up

If you switch to an HDMI input and see a black screen or "No Signal" message, the device connected to that port may not be turned on. Turn on your cable box, gaming console, streaming device, or other connected equipment and wait a few seconds for the signal to reach your TV.

If the device is on but still shows no signal, check the HDMI cable itself. Unplug it from both the TV and the device, wait five seconds, and plug it back in firmly. Make sure the cable is fully inserted into the port — a loose connection is the most common reason for signal loss.

Try a different HDMI cable if you have one available. Some cables wear out or develop internal damage that prevents signal from passing through. If a different cable works, the original cable is faulty and should be replaced.

Switching between multiple devices on the same TV

If you have several devices connected to different HDMI ports — such as a cable box on HDMI 1, a gaming console on HDMI 2, and a streaming device on HDMI 3 — you can switch between them quickly using your remote. Each time you press Input or Source, the menu shows all connected ports with labels.

Samsung TVs allow you to rename HDMI ports so you can identify them more easily. Access your TV's settings menu, find the Input or HDMI settings section, and look for an option to label each port. You can name HDMI 1 "Cable Box," HDMI 2 "PlayStation," and so on. These custom names will appear in the input menu, making it faster to find the device you want.

Some newer Samsung models support HDMI-CEC, a feature that lets connected devices switch your TV to the correct input automatically. When you turn on a device with HDMI-CEC enabled, your TV may switch to that input without you pressing any buttons. You can turn this feature on or off in your TV's settings under HDMI or External Device Manager.

Using your Samsung TV remote to control input switching

Modern Samsung remotes, especially the Samsung Smart Remote, have a dedicated input button that works faster than older models. Press it once to open the input menu, or press it multiple times to cycle through inputs one at a time. Some remotes also have a small touchpad that lets you navigate the input menu by swiping.

If you have a voice-enabled Samsung remote, you can say "HDMI 2" or "Switch to HDMI 3" and the TV will change inputs automatically. This feature works on Samsung TVs from 2016 and newer that support voice commands. Make sure your remote has a microphone button (usually marked with a microphone icon) and that voice control is turned on in your TV's settings.

You can also use the Samsung SmartThings app on your phone to change inputs if you have a compatible Samsung TV. Open the app, select your TV, and look for an input or remote control option. This method is useful if your physical remote is not nearby, though it requires your phone and TV to be on the same Wi-Fi network.

Troubleshooting input switching problems

If the Input button on your remote does not respond, the remote batteries may be dead. Replace the batteries with fresh ones and try again. If the button still does not work, the remote itself may be faulty and need replacement.

If the input menu appears but you cannot navigate it, try unplugging your TV from power for 30 seconds, then plugging it back in. This resets the TV's system and often fixes menu navigation problems. Wait for the TV to fully boot up before trying to change inputs again.

If your TV is stuck on one input and will not switch, a software update may have caused the issue. Check your TV's settings menu for a Software Update or System Update option. read and install any available updates, then restart your TV and try changing inputs again.

Frequently Asked Questions

Can I set a default HDMI input so my TV opens to it automatically?

Yes. Go to your TV's Settings menu, find the Input or External Device Manager section, and look for a Default Input or Startup Input option. Select the HDMI port you use most often, and your TV will switch to it when you turn the TV on. This saves you from manually selecting the same input every time.

Why does my TV switch inputs on its own?

HDMI-CEC is likely enabled on your TV. This feature lets connected devices automatically switch your TV to their input when they turn on. You can turn it off in your TV's settings under HDMI or External Device Manager. Look for an option called HDMI-CEC, Anynet+, or Consumer Electronics Control and disable it if you prefer manual control.

What if I have more than four HDMI ports?

Most Samsung TVs have four built-in HDMI ports, but you can connect additional devices using an HDMI splitter or switch box. These devices plug into one HDMI port and allow you to connect multiple devices to that single port. You then switch between devices using the splitter's remote or buttons instead of your TV's input menu.

Does changing HDMI inputs affect my TV settings or picture quality?

No. Switching between HDMI inputs does not change your TV's brightness, contrast, color, or other picture settings. Each input can have its own separate picture settings if you want to customize them — for example, you might prefer different settings for gaming versus watching cable. These settings stay the same each time you return to that input.
