How to Screen Mirror Your PC to a Samsung TV

The fastest way to mirror your PC screen to Samsung TV

You can mirror your PC to a Samsung TV using Miracast, which is built into Windows 10 and Windows 11. On your PC, press Windows key + K to open the Quick Settings panel, then select your Samsung TV from the list of available devices. Your screen will appear on the TV within a few seconds. This method works wirelessly and requires no cables or extra software.

If Miracast does not find your TV, make sure both devices are on the same Wi-Fi network and that your Samsung TV has screen mirroring turned on. On most Samsung TVs, this setting is called SmartThings or Screen Mirroring and is found in the TV's settings menu under Connections or Network.

Key Takeaways

Press Windows key + K on your PC to open the Quick Settings panel and select your Samsung TV to begin mirroring when ready.
Both your PC and TV must be connected to the same Wi-Fi network for wireless mirroring to work.
Samsung TVs require screen mirroring to be enabled in the TV's settings menu before your PC can detect it.
If Miracast does not work, you can use the Samsung SmartThings app on your PC as an alternative mirroring method.
HDMI cables provide a reliable wired connection if wireless mirroring is unstable or unavailable.

Check that your Samsung TV supports screen mirroring

Most Samsung TVs made after 2016 support wireless screen mirroring through Miracast. Older models may not have this feature. To confirm your TV supports it, look in the TV's settings menu for an option called SmartThings, Screen Mirroring, Wireless Display, or Miracast. If you find any of these options, your TV is compatible.

You can also check your TV's model number on the back or in the settings menu and search the Samsung support website for your specific model. The support page will list which features your TV includes. If your TV does not support Miracast, you can still use an HDMI cable or a streaming device like a Chromecast or Fire Stick instead.

Enable screen mirroring on your Samsung TV

Before your PC can find your TV, you must turn on the mirroring feature on the TV itself. On most Samsung TVs, press the Menu button on your remote and navigate to Settings. From there, look for Connections or Network and select Screen Mirroring or SmartThings. Toggle the setting to On.

Some newer Samsung TVs use the SmartThings app instead. If you do not see a screen mirroring option in the settings menu, open the SmartThings app on your TV (it may be pre-installed) and look for a mirroring or casting option there. Leave this setting on while you attempt to mirror from your PC.

Connect both devices to the same Wi-Fi network

Wireless mirroring only works when your PC and Samsung TV are connected to the same Wi-Fi network. Check your PC's Wi-Fi connection by clicking the network icon in the system tray at the bottom right of your screen. Make sure you are connected to the same network name (SSID) that your TV is using.

To check your TV's network connection, go to the TV's settings menu and look for Network Status or Wi-Fi. The network name should match the one your PC is using. If they are on different networks, connect your TV to the correct network first. Once both devices are on the same network, they can communicate with each other.

Mirror your screen using Windows Quick Settings

On your PC, press Windows key + K together. This opens the Quick Settings panel on the right side of your screen. Wait a moment for your PC to scan for nearby devices. Your Samsung TV should appear in the list with its model name or the name you gave it in the TV's settings.

Click on your TV's name to begin mirroring. Your PC screen will appear on the TV within 5 to 10 seconds. While mirroring is active, you can still use your PC normally—everything you do will show on the TV. To stop mirroring, press Windows key + K again and select Disconnect.

Troubleshoot if your TV does not appear

If your Samsung TV does not show up in the Quick Settings list, first restart both devices. Turn off your TV completely, wait 30 seconds, and turn it back on. Then restart your PC. After both devices have restarted, try pressing Windows key + K again.

If the TV still does not appear, check that screen mirroring is enabled on the TV and that both devices are truly on the same Wi-Fi network. Move your PC closer to the TV and router to rule out weak signal. If Miracast continues to fail, try using the Samsung SmartThings app on your PC instead, or use an HDMI cable as a wired backup. Some older routers or networks with unusual security settings can block Miracast, so switching to a different Wi-Fi network may help if one is available.

Use Samsung SmartThings app as an alternative

If Miracast does not work, you can mirror using the Samsung SmartThings app. read and install the SmartThings app on your PC from the Microsoft Store. Open the app and sign in with your Samsung account (create one if you do not have one). The app will scan for your TV on the same network.

Once your TV appears in the app, select it and look for a Mirror, Cast, or Screen Share option. The exact button name varies by app version, but it is usually near the top of the screen. Click it to begin mirroring. This method is more reliable on some networks and older TV models, though it requires an extra app installation.

Use an HDMI cable if wireless mirroring fails

If wireless mirroring is not working and you need a reliable connection, use an HDMI cable instead. Connect one end of an HDMI cable to the HDMI port on your PC (or use a USB-C to HDMI adapter if your PC does not have an HDMI port). Connect the other end to any available HDMI port on your Samsung TV.

On your TV remote, press the Input or Source button and select the HDMI port you plugged the cable into. Your PC screen will appear on the TV when ready. HDMI connections are faster and more stable than wireless mirroring, though they require a cable and limit how far you can sit from the TV. This is the best option if you plan to mirror for long periods or need a rock-solid connection.

Frequently Asked Questions

Can I mirror my PC to a Samsung TV if they are on different Wi-Fi networks?

No, Miracast requires both devices to be on the same Wi-Fi network to communicate. If your PC and TV are on different networks, connect them to the same one first. Some guest networks may also block mirroring, so try connecting both to your main network if available.

Will mirroring slow down my PC or internet speed?

Mirroring uses your Wi-Fi connection but does not significantly slow your internet speed or PC performance. You can continue using your PC normally while mirroring. If you notice lag or stuttering, move closer to your router or reduce the number of other devices using Wi-Fi.

What if my PC does not have a Windows key + K shortcut?

If the keyboard shortcut does not work, open the Settings app on your PC, go to System, then Display, and look for Connect to a wireless display. Click that option to open the same mirroring panel. Some older versions of Windows may have this option in a different location.

Can I use mirroring while playing games or watching videos?

Yes, you can mirror while playing games or watching videos. However, wireless mirroring may introduce slight delay (usually under one second), which can affect fast-paced games. For gaming, an HDMI cable provides a more responsive connection with no lag.

Why does my screen keep disconnecting from the TV?

Disconnections usually happen because of weak Wi-Fi signal, interference from other devices, or the TV's screen mirroring feature timing out. Move your PC closer to the router, reduce interference by turning off nearby wireless devices, and make sure screen mirroring is still enabled on your TV. If problems continue, use an HDMI cable instead.
