How to Connect Your Devices to a Samsung TV

The fastest way to connect depends on what device you're using

Samsung TVs connect to phones, laptops, tablets, and streaming devices through three main methods: HDMI cables, wireless casting, and built-in apps. The method you choose depends on what you're connecting and whether you want a permanent setup or temporary screen sharing. Most Samsung TVs made in the last five years support all three, though older models may lack wireless features.

Before you start, make sure your Samsung TV is powered on and connected to the same WiFi network as the device you're connecting (for wireless methods). If you're using an HDMI cable, you'll need to know which HDMI port on the back or side of your TV you're plugging into — most TVs have two to four ports labeled HDMI 1, HDMI 2, and so on.

Key Takeaways

HDMI cables work with any device that has an HDMI port and require no setup beyond plugging in and selecting the correct input on your TV remote.
Samsung's SmartThings app lets you cast from Android phones and tablets wirelessly, and works on the same WiFi network as your TV.
AirPlay (for iPhones and iPads) and Miracast (for Windows laptops) are built into most Samsung TVs from 2016 onward and require no separate app.
Streaming devices like Roku, Fire Stick, and Apple TV plug directly into an HDMI port and give you access to apps without connecting a personal device.
If wireless casting fails, check that both devices are on the same WiFi network and that your TV's wireless feature is turned on in the settings menu.

Connecting with an HDMI cable

An HDMI cable is the most reliable connection method because it requires no setup and works with almost any device. Plug one end of the HDMI cable into the HDMI port on your device (laptop, streaming box, gaming console, or cable box) and the other end into any HDMI port on the back or side of your Samsung TV.

Once both ends are plugged in, pick up your TV remote and press the Input or Source button. A menu will appear showing all available inputs — select the HDMI port number you just used (for example, HDMI 1 or HDMI 3). The picture from your device should appear on the screen within a few seconds. If it doesn't, unplug the cable, wait five seconds, and plug it back in.

HDMI cables are inexpensive (usually $5 to $15) and last indefinitely. If you plan to leave a device connected permanently — like a cable box, gaming console, or streaming device — HDMI is the best choice because it doesn't depend on WiFi or battery power.

Casting from an Android phone or tablet using SmartThings

Samsung's SmartThings app is the official wireless casting tool for Android devices. read it from the Google Play Store, open it, and tap the plus icon (+) to add a new device. Select your Samsung TV from the list of available devices and follow the on-screen prompts to connect.

Once your TV is added to SmartThings, open any app on your Android phone or tablet (YouTube, Netflix, photos, web browser) and look for a cast icon — it looks like a rectangle with a WiFi symbol in the corner. Tap it and select your Samsung TV. The content will stream to your TV within a few seconds. To stop casting, tap the cast icon again and select "Disconnect."

SmartThings casting works best when your phone and TV are on the same WiFi network. If casting fails, restart both devices and check that WiFi is turned on. Some apps (like older versions of Netflix) may not support casting — if that's the case, try a different app or use an HDMI cable instead.

Casting from an iPhone or iPad using AirPlay

Samsung TVs made in 2016 or later have AirPlay built in, so you don't need to read an app. On your iPhone or iPad, swipe down from the top-right corner to open Control Center. Tap Screen Mirroring and select your Samsung TV from the list. Your entire phone or tablet screen will appear on the TV.

If you don't see your TV in the Screen Mirroring list, make sure both devices are on the same WiFi network. Go to your Samsung TV's settings, find AirPlay or AirPlay and HomeKit, and turn it on. Then try Screen Mirroring again on your iPhone or iPad.

You can also cast individual apps without mirroring your whole screen. Open an app like YouTube or Apple TV, tap the AirPlay icon (it looks like a triangle with WiFi lines), and select your TV. This uses less battery and lets you keep using your phone for other things while the app plays on the TV.

Connecting a Windows laptop using Miracast

Windows 10 and Windows 11 laptops can cast to Samsung TVs using Miracast, which is built into most Samsung models from 2016 onward. On your laptop, press the Windows key and the K key at the same time to open the Quick Settings panel. Click Connect and select your Samsung TV from the list.

Your laptop screen will appear on the TV. To stop casting, open the Quick Settings panel again and click Disconnect. Miracast works best when your laptop and TV are on the same WiFi network and within 30 feet of each other.

If your TV doesn't appear in the Connect list, go to your Samsung TV's settings and look for Miracast or Screen Mirroring. Turn it on, then try connecting again from your laptop. If it still doesn't work, restart both devices and try once more.

Plugging in a streaming device

Streaming devices like Amazon Fire Stick, Roku, Google Chromecast, and Apple TV connect directly to your TV's HDMI port and give you access to apps without needing to connect your phone or laptop. Plug the device into an HDMI port, switch your TV's input to that port, and follow the on-screen setup instructions.

Most streaming devices ask you to connect to your WiFi network and sign in with an account (Amazon, Roku, Google, or Apple). Once set up, you can browse and launch apps directly from the device's remote control. This is the most convenient option if you watch streaming services regularly because you don't have to keep your phone connected.

Streaming devices are separate purchases (typically $30 to $100), but they're worth it if you use your TV frequently. They also tend to be more reliable than casting from a phone because they have their own processor and don't depend on your phone's battery or WiFi signal strength.

Troubleshooting when nothing appears on the screen

If you've plugged in a cable or started casting and nothing shows up, start with these steps in order. First, check that you selected the correct HDMI input on your TV remote — press Input or Source and make sure the port number matches where you plugged in the cable. Second, unplug the cable or disconnect the wireless connection, wait 10 seconds, and try again.

For wireless casting, restart both your TV and the device you're casting from. Then check that both are on the same WiFi network — look at your TV's network settings and your phone's WiFi settings to confirm they show the same network name. If they're on different networks, connect your phone to the same network as your TV and try casting again.

If you're using an HDMI cable and still see nothing, try a different HDMI port on your TV. Some ports may not work if they're damaged or if your TV has a port reserved for a specific function (like eARC for soundbars). If the device works in a different port, that port is likely faulty and you should use a different one going forward.

Frequently Asked Questions

Do I need to buy a special cable to connect my device to a Samsung TV?

No. A standard HDMI cable works with any Samsung TV and any device with an HDMI port. You can buy one at any electronics store or online for $5 to $15. Make sure it's labeled HDMI 2.0 or higher if you're connecting a 4K device, but for most uses a basic cable is fine.

Can I connect two devices to my Samsung TV at the same time?

Yes, but only one can display on the screen at a time. If you have two HDMI cables plugged in, you can switch between them using the Input button on your remote. For wireless casting, you can only cast from one device at a time — you'll need to disconnect one before connecting another.

Why does my phone keep disconnecting from my TV?

Wireless casting drops when your phone moves too far from the TV, when WiFi signal is weak, or when your phone's WiFi turns off to save battery. Keep your phone within 30 feet of the TV and in the same room if possible. Check your phone's WiFi settings to make sure it's still connected to the network, and turn off battery saver mode if it's on.

What if my Samsung TV is older and doesn't have wireless features?

Older Samsung TVs (before 2016) may not support AirPlay or Miracast. Use an HDMI cable instead, or buy a separate streaming device like a Roku or Fire Stick that plugs into an HDMI port. These devices add wireless casting and app support to any TV.

Can I connect my Samsung TV to the internet without a streaming device?

Yes. Most Samsung TVs have built-in WiFi and can connect directly to your home network. Go to your TV's settings, find Network or WiFi, and select your network name. Enter your WiFi password and your TV will connect. Once connected, you can use the TV's built-in apps (like Netflix, YouTube, and Samsung TV Plus) without needing an external device.
