You’re sitting there with a bowl of popcorn, ready to dive into a movie, but the screen is just a black void of nothingness because your Xbox is on HDMI 2 and the TV is stubbornly sitting on HDMI 1. It's annoying. Samsung TVs are generally sleek and reliable, but their software—especially the newer Tizen OS versions found on Neo QLED or OLED models—can sometimes feel like a maze when you just want to switch from your cable box to a PlayStation. Knowing exactly how to change the HDMI on a Samsung TV isn't just about clicking a button; it’s about understanding the shortcuts that save you from digging through five layers of settings menus.
Sometimes the "Source" button on the remote works instantly. Other times, you're dealing with a "Smart Remote" that doesn't even have a dedicated source button, leaving you to flick through a horizontal bar at the bottom of the screen while the TV tries to show you ads for Samsung TV Plus.
The Standard Way (And Why It Fails)
On most modern Samsung remotes, you’re looking for the Home button. It looks like a little house. You press that, and a ribbon menu pops up at the bottom. You have to navigate left, past all your apps like Netflix and Hulu, until you hit "Source" or "Connected Devices." Honestly, it’s a bit of a trek. If your TV is a few years older, you might have the "Source" button right there at the top of the remote. Pressing it toggles through the inputs one by one.
But here is the kicker: if a device isn't powered on, some Samsung TVs will actually skip that HDMI port in the rotation. If you're trying to switch to your Nintendo Switch and it’s in sleep mode, the TV might act like that port doesn't exist. You have to wake the device up first. It’s a "smart" feature that often feels pretty dumb when you’re just trying to verify a connection.
Dealing with the Smart Hub
Samsung’s 2022 through 2025 models use a full-screen Smart Hub. When you hit Home, it takes over the whole display. To change your HDMI here, look for the "Menu" option on the left-hand sidebar. From there, you go to "Connected Devices." It’s more clicks than it used to be. Many users, especially those using the solar-powered Samsung remotes, find this transition jarring compared to the old "Source" button days.

How to Change the HDMI on a Samsung TV Without a Remote
We’ve all been there. The remote is buried in the couch cushions, or the batteries finally died. Don't panic. Every Samsung TV has a physical button somewhere on the frame, though they hide them well. Usually, it's under the Samsung logo at the bottom center, or tucked away on the back right side.
This is the Control Controller.
It’s often a single button that acts as a directional pad. You press it once to bring up a small menu on the screen. Then, you "long press" or "short press" to move the highlight to the Source icon. Once you're on the right input, you hold the button down to select it. It’s clunky. It feels like 1995 technology hidden inside a 4K masterpiece. But it works. If your TV has a tiny joystick instead of a single button, it’s much easier—just nudge it toward the source icon and click it in like a button.
Using the SmartThings App
If you’re part of the Samsung ecosystem, the SmartThings app is your best friend. Since your TV is likely connected to your Wi-Fi, you can open the app on your phone, find your TV, and use the digital remote. The benefit here? You get a dedicated "Source" list that lets you jump directly to HDMI 3 without scrolling through everything else. It’s the fastest workaround for a lost remote, provided your TV hasn't dropped its Wi-Fi connection—which, let's be real, happens more than we'd like.

The HDMI-CEC "Magic" Trick
If you hate changing inputs manually, you need to enable Anynet+ (HDMI-CEC). This is a protocol that allows devices to talk to each other over the HDMI cable.
- Go to Settings.
- Select General (or Connection on newer models).
- Find External Device Manager.
- Toggle Anynet+ (HDMI-CEC) to ON.
Why do this? Because once it's on, simply turning on your Blu-ray player or console will command the Samsung TV to switch to that HDMI port automatically. No remote needed. It’s arguably the best way to handle inputs, though it can get messy if you have a soundbar that gets confused about which device is "active."
Troubleshooting: When "No Signal" Appears
Sometimes you change the HDMI, but you’re met with a "No Signal" or "Check Device Power" message. This is rarely a hardware failure and usually a handshake issue. HDMI handshaking is the process where the TV and the device agree on the resolution and encryption (HDCP).
The "Cold Boot" Fix
If a port isn't showing up or won't switch, perform a cold boot on the TV. This isn't just turning it off; it's clearing the cache. Hold the Power button on your remote for about 10 seconds until the TV turns off and then flashes the "QLED" or "Samsung" logo as it turns back on. This resets the software's recognition of the HDMI ports.

Cable Quality Matters
If you're trying to run a PS5 or Xbox Series X at 4K/120Hz, an old HDMI 1.4 cable won't cut it. You need a High-Speed or Ultra High-Speed cable (HDMI 2.1). If the cable is subpar, the Samsung TV might see the device but refuse to switch to it because it can't maintain the data stream. It’s a silent killer of movie nights.
Voice Commands for the Lazy (Or Efficient)
If your remote has a microphone button, use it. Say "Switch to HDMI 1" or "Change source to PlayStation." Bixby—or Alexa/Google Assistant if you’ve linked them—is surprisingly good at this specific task. It bypasses all the menu clicking entirely. It’s the closest thing we have to just snapping our fingers and having the TV obey.
Expert Insight: Managing Multiple Inputs
For those with more than four devices, a basic HDMI switch is usually the answer. However, be careful. Samsung TVs can sometimes get "confused" by external switches if they don't support the same version of Anynet+ that the TV uses. Always look for a powered HDMI switcher rather than a passive one. Passive switchers draw power from the HDMI port itself, which can lead to flickering or the Samsung TV failing to recognize the "Source" change entirely.
Practical Steps to Take Now
To ensure you never struggle with how to change the HDMI on a Samsung TV again, set yourself up for success with these three moves:
- Rename your inputs: Go to the Source menu, highlight an input (like HDMI 1), and press "Up" to find the "Edit" option. Rename it to "Xbox" or "Apple TV" so you aren't guessing which number is which.
- Move to Home: You can actually move your most-used HDMI ports to the very front of your Smart Hub ribbon. Highlight the source, hold the Select button, and choose "Move."
- Check your firmware: Samsung releases updates that specifically fix HDMI handshake bugs. Go to Settings > Support > Software Update to make sure you're on the latest version, especially if you have a newer soundbar.
By organizing your inputs and enabling Anynet+, the process of switching between devices becomes almost invisible. You stop "managing" your TV and start actually watching it.
Actionable Insight: If your Samsung TV frequently "loses" your HDMI devices, the most effective fix is disabling the "Instant On" feature in the settings (sometimes found under Power and Energy Saving as "Start with Last App"). This forces the TV to do a fresh hardware sweep every time it boots, ensuring it sees every connected HDMI device right away.
