Screen mirroring sends your phone or computer display to your Fire TV Stick 4K in real time
Screen mirroring is the feature that lets you broadcast what you see on your phone, tablet, or computer directly to your TV through the Fire TV Stick 4K. The Stick receives the signal wirelessly and displays it on your screen. You do not need to plug anything in or read a separate app on your TV — the Fire TV Stick handles the receiving end automatically.
The process differs slightly depending on whether you are mirroring from an iPhone, Android phone, or computer, but the basic steps are the same: enable mirroring on your device, find your Fire TV Stick in the list of available receivers, and tap to connect. Most connections happen within a few seconds.
Key Takeaways
- Your Fire TV Stick 4K must be powered on and connected to the same Wi-Fi network as your phone or computer for mirroring to work.
- Android phones use the Quick Settings menu to find the Cast or Screen Mirroring option, while iPhones use Control Center and require AirPlay compatibility.
- Windows computers can mirror through the Settings app under System > Display > Multiple Displays, and Mac computers use AirPlay through the menu bar.
- If your device does not find the Fire TV Stick, restart both devices and confirm they are on the same Wi-Fi network.
- Mirroring works best when your device and Fire TV Stick are within 20 to 30 feet of your Wi-Fi router.
How to mirror from an Android phone or tablet
Open the Quick Settings panel on your Android device by swiping down from the top of the screen twice. Look for an option labeled Cast, Screen Mirroring, or Smart View — the exact name depends on your phone's manufacturer. Tap it to see a list of available devices.
Your Fire TV Stick 4K should appear in the list with a name like "Fire TV Stick-XXXX" (the X's are random letters and numbers). Tap the Fire TV Stick name to start mirroring. Your phone screen will appear on your TV within a few seconds. To stop mirroring, open Quick Settings again and tap the Cast option, then select Stop Casting.
If your device does not show a Cast option in Quick Settings, check your phone's Settings app under Display or Connected Devices — some Android phones hide the mirroring feature in a different location. Samsung phones often call it SmartThings or SmartView and may require you to open the SmartThings app instead.
How to mirror from an iPhone or iPad
Open Control Center by swiping down from the top-right corner of your iPhone or iPad (or swiping up from the bottom on older models). Look for a button labeled Screen Mirroring or AirPlay. Tap it to see available receivers.
The Fire TV Stick 4K will appear in the list if it supports AirPlay — check your Stick's settings to confirm AirPlay is turned on. Tap the Fire TV Stick name to begin mirroring. Your iPhone or iPad screen will appear on your TV. To stop, open Control Center again, tap Screen Mirroring or AirPlay, and select Stop Mirroring.
Not all Fire TV Stick models support AirPlay — the 4K model does, but older generations may not. If you do not see your Fire TV Stick in the AirPlay list, check the device settings on your Stick itself. Go to Settings > Display and Sound > AirPlay and HomeKit, then make sure AirPlay is set to On.
How to mirror from a Windows computer
On Windows 10 or 11, open the Settings app and go to System > Display > Multiple Displays. Scroll down and look for a section called Cast to devices or Wireless display settings. Click Launch the wireless display app or Connect to a wireless display.
A window will open showing available devices. Your Fire TV Stick 4K should appear in the list. Click it to start mirroring. Your computer screen will appear on your TV. To disconnect, click the device name again and select Disconnect.
If the wireless display app does not find your Fire TV Stick, make sure both devices are on the same Wi-Fi network. You can also try using the keyboard shortcut Windows Key + P to open the projection menu, then select Connect to a wireless display.
How to mirror from a Mac computer
Click the AirPlay icon in the menu bar at the top of your Mac screen — it looks like a rectangle with a triangle at the bottom. A dropdown menu will show available AirPlay receivers. Your Fire TV Stick 4K should appear in the list if AirPlay is enabled on the Stick.
Click the Fire TV Stick name to start mirroring. Your Mac screen will appear on your TV. To stop mirroring, click the AirPlay icon again and select Turn Off AirPlay.
If you do not see an AirPlay icon in your menu bar, go to System Preferences > Displays and check the box next to Show mirroring options in the menu bar when available. Older Mac models may not support AirPlay to Fire TV — check Apple's support page to confirm your Mac is compatible.
Troubleshooting when mirroring does not work
The most common reason mirroring fails is that your device and Fire TV Stick are not on the same Wi-Fi network. Check that both are connected to the same network name (SSID). If your router broadcasts separate 2.4 GHz and 5 GHz networks, try connecting both devices to the 2.4 GHz band, as some older devices have trouble with 5 GHz.
If your device still does not find the Fire TV Stick, restart both devices. Unplug the Fire TV Stick from power for 10 seconds, then plug it back in and wait for it to fully boot. Restart your phone or computer as well. Once both devices are back online and on the same network, try mirroring again.
Distance and obstacles can also affect the connection. Move your device closer to your Wi-Fi router and Fire TV Stick — ideally within 20 to 30 feet. Walls, metal objects, and other electronics can weaken the signal. If mirroring is slow or keeps dropping, try moving your router or repositioning the Fire TV Stick.
If mirroring works for a few seconds and then stops, your Wi-Fi connection may be unstable. Check your internet speed using a speed test app. Fire TV Stick 4K works best with a Wi-Fi connection that has at least 5 Mbps read speed for smooth mirroring.
What to expect when mirroring is working
When mirroring is active, your device screen appears on your TV with a slight delay — usually less than one second. This lag is normal and does not mean something is wrong. Video and audio both come through, though audio may be slightly delayed on some connections.
Mirroring uses your Wi-Fi network, so it will slow down your internet speed slightly. If you are streaming video or downloading files on another device while mirroring, you may notice buffering or lag. Closing other apps and pausing downloads can help.
The Fire TV Stick will continue mirroring until you stop it or your device goes to sleep. If your phone screen locks, mirroring stops automatically. Unlock your phone to resume mirroring.
Frequently Asked Questions
Do I need to pair my device with the Fire TV Stick before mirroring?
No pairing is required. As long as both devices are on the same Wi-Fi network, your phone or computer should find the Fire TV Stick automatically when you open the mirroring menu. Just tap or click the Stick name to connect.
Can I mirror audio only without the video?
Screen mirroring sends both video and audio together — you cannot separate them. If you only want to play audio through your TV speakers, use a music streaming app like Spotify or YouTube Music, which have their own casting features built in.
Why does mirroring stop when I get a phone call?
Incoming calls interrupt mirroring on most phones because the call takes over your screen. When you hang up, you can resume mirroring by opening the Cast or AirPlay menu again and selecting your Fire TV Stick.
Can multiple people mirror to the same Fire TV Stick at the same time?
No, only one device can mirror to the Fire TV Stick at a time. If someone else tries to mirror while you are already connected, their device will either fail to connect or disconnect you. You must stop mirroring before another device can take over.
Is screen mirroring the same as casting?
Casting and mirroring are similar but not identical. Mirroring sends your entire device screen to the TV. Casting sends only a specific app or video to the TV, leaving your phone free to do other things. The Fire TV Stick supports both, depending on which app you use.
