How To Screen Mirroring Windows 10 to Samsung Smart TV

How many times when we want to cast our computer into TV. For ex: we have videos stored on our computer that can’t be broadcasted or transferred to our TV. Or we saved a bunch of pictures that we want to share with our family on a bigger screen. Whatever our reason is, it is a must to know how to connect our computer to our televisions. And thanks to advanced technology, we can choose from different products or applications that can mirror Windows 10 PC to Samsung TV, either wired or wireless. So without further ado, check out the detailed instructions below and choose what will suit your needs.

Three Easy Methods to Mirror Windows PC to Samsung TV

Method 1: Using Miracast Device – Mirror Laptop to TV Wirelessly

Here’s the another wireless solution, the Miracast technology. It is often described as “HDMI over Wi-Fi” because it enables different devices to establish a connection using wireless networks. This was first introduced in Windows 8.1 and later on, almost all laptops and OS adopt the said tech. Miracast is capable of playing HD videos on your TV. Furthermore, it can display all the ongoing activities on your monitor. To know how to connect PC to TV, refer below:

  • Navigate to your computer settings and then click on “Devices”.
  • Next, go to “Connected devices” and hit “Add a device”.
  • Wait for your computer to finish detecting devices and from the available options, click on your TV.
  • In the event that your computer doesn’t automatically connect your TV, right-click on your mouse and choose “Display settings”.
  • From there, set the multiple displays to “Duplicate these displays” and then hit “Connect to a wireless display”.
  • Once your TV is detected, click on the “Connect” button to finally mirror PC to TV.

Although it can be considered a breakthrough in terms of connectivity, there are still some issues persisting concerning Miracast. First, it doesn’t stream your device all the time. And up until now, users can’t find solutions for this. Second, you might suffer from lags between your computer and TV. And lastly, it does not allow multitasking.

Method 2: Using Chromecast – Reliable Method to Mirror PC to TV

Next, you can rely on Chromecast. It is a streaming device designed to connect your computer or mobile gadgets to TV. With this, you can cast your music or pictures and watch online videos from sharing sites like YouTube, HBO, and Netflix. Similar to the first one, the process of connecting your devices are pretty straightforward. But if you have difficulties, follow this guide to stream PC to TV:

  • Get your Chromecast device and plug the HDMI cable into the port of your TV and then connect the USB wire into any power outlet or compatible port.
  • Search for “Google Cast” on your Google Chrome Store and install it as an extension.
  • Open a new window on your browser and click the “Cast” button.
  • Finally, when your laptop detects the external devices, search for your TV and click on it. And then you can mirror PC to TV.

Even though Chromecast seems to be a good alternative, bear in mind that it operates over Wi-Fi. Therefore, if you have a weak internet connection, only to find some lag and low-quality display.

Simply put, both services allow you to stream films, photographs, and other content from your phone to your Smart TV. That’s all you really need to know. But if you’re looking for a more in-depth definition, we’ve got it right here for you.

How to mirror Samsung phone to Samsung TV?

The answer is right in the name: screen mirroring. This feature allows you to mirror what is now displayed on your phone’s screen to a larger screen, such as a Smart TV. Whatever is now displayed on your phone will be displayed on the television, whether it is a video, a photo, or a Settings menu. It is possible that if you do an action on your phone (for example, switching to a different app), that action will also be displayed on the other screen. Smart View is the name given to the screen mirroring feature on Samsung devices. You may effortlessly mirror your screen with Smart View by just pressing on the Smart View icon and following a few simple instructions that are provided. The screen mirroring technology for iPhones is known as AirPlay, and it accomplishes the same exact thing as on other devices – it mirrors photos, videos, and other data. AirPlay is similar to but slightly different from, using Smart View on a mobile device. Whichever model you have, it’s a fantastic way to share files, images, and other media from your phone directly on the screen of your Smart TV.

What exactly is casting?

It is not immediately evident what the term “casting” means due to the fact that it can be used in a variety of contexts. Casting, on the other hand, refers to the transmission of sound and images in real-time through the internet via phones and televisions.

How to cast Samsung phone to TV?

Certain programs, such as Netflix or YouTube, allow you to cast videos directly from your phone to a large screen display. In the absence of a Smart TV, you can stream videos using third-party casting devices such as Google Chromecast or Amazon Firestick, among others.

When you cast a video or a movie, the video or movie will only appear on the television. The video is controlled by your phone, but you can also close the app and do other things without stopping the video as long as the phone is still connected to the computer or other device. It’s an extremely convenient way to watch a movie while also using your phone.

Step 1: Swipe down from the top screen to reveal the Quick panel, then press on the Smart View symbol to activate the feature. Step 2: From the list of available devices, select your television (depending on the TV, you may need to enter a PIN). Step 3: On the pop-up window that says ‘Start casting with Smart View?’, select Start now from the drop-down menu that appears. If the mirroring picture appears to be too small on the screen, the aspect ratio can be adjusted.

Step 1: Select Smart View Options from the drop-down menu (three vertical dots). Step 2: Select the Phone aspect ratio from the Settings menu. Step 3: On the connected device, select Fullscreen to make it appear in full-screen mode. If you like to go to full screen on a connected device once Smart View begins mirroring your phone’s screen, you may enable ‘Remember settings’, which is a convenient feature for you. Please keep in mind that some applications may need to be restarted as a result of this. Note: Both the mobile phone and the television must be linked to the same Wi-Fi network. Some televisions may require you to change inputs or enable screen mirroring before they will function properly.

How to screen mirror from your iPhone to a Samsung TV in 2 different ways

Email icon An envelope. It indicates the ability to send an email.

Email icon A stylized bird with an open mouth, tweeting.

LinkedIn icon The word in.

  • You can screen mirror, or AirPlay, content from your iPhone to your Samsung TV.
  • Most Samsung TV models from 2018 or later are compatible with the current version of AirPlay called AirPlay 2.
  • If your Samsung TV isn’t AirPlay 2-compatible, or if you’d prefer a wired connection, you can still use a lightning-to-HDMI adapter to mirror your screen.

Screen mirroring is a common feature on most new technology that allows you to cast content from the screen of one device to the screen of another. Screen mirroring goes by many different names, but on Apple devices, it’s called AirPlay.

Though AirPlay is an Apple feature, since the advent of AirPlay 2 in 2018, it has become much easier to connect across device ecosystems. If you have a Samsung Smart TV made in 2018 or later, you will most likely be able to use AirPlay — see if your model is on this list to be sure.

There are two ways to access AirPlay on your iPhone — you can either select Screen Mirroring from the Control Center to mirror your entire iPhone screen, or you can select the AirPlay icon from within some apps to cast content from your iPhone to your TV. Alternatively, you can connect your iPhone to your Samsung TV with an HDMI cable to achieve the same effect. Here’s how to do it all.

How to turn on AirPlay on a Samsung TV

Before you can use screen mirroring or AirPlay, you need to first make sure the feature is enabled on your Samsung TV.

Using your TV remote, go to Settings and select General.

Choose Apple AirPlay Settings from the menu.

Select AirPlay and turn it to On.

How to screen mirror an iPhone to a Samsung TV using AirPlay 2

Quick tip: Before you begin, make sure your iPhone and Samsung TV are connected to the same Wi-Fi network.

How to mirror your entire iPhone screen from the Control Center

Swipe down from the top-right of your iPhone’s screen to bring up the Control Center. For older iPhone models with a home button, the Control Center is accessed by swiping up from the bottom of the screen.

Tap Screen Mirroring beside an icon of two overlapping rectangles.

Select your Samsung TV from the list of available devices.

If a passcode appears on your Samsung TV, enter it into the pop-up on your iPhone.

Your entire iPhone screen should then begin mirroring onto your Samsung TV. When you play a video on your iPhone, your TV should automatically format it to full-screen.

How to AirPlay content from within apps

If you’d rather not mirror your entire phone’s screen to your TV, some major media services like Amazon Prime Video, HBO Max, and Hulu have an AirPlay button directly in their apps. Unfortunately, Netflix no longer includes the in-app AirPlay option.

Some built-in iPhone apps like the Photos app have the AirPlay option as well, located in the Share menu.

Once you’ve made sure your phone and your TV are on the same Wi-Fi network, open the app and select the media you want to play.

Find the AirPlay button — a rectangle with a triangle beneath it, usually near the top-right or top left corner of the screen — and tap it. If you’re trying to AirPlay from the Photos app, tap the Share button, then select AirPlay.

Choose the name of your Samsung TV from the list of available devices.

If a passcode appears on your Samsung TV, enter it into the pop-up on your iPhone.

Your photo or video should then begin mirroring onto your Samsung TV.

How to screen mirror an iPhone to Samsung TV with an HDMI cord and Lightning Digital AV adapter

If you find it easier to use a wired connection, or if your devices aren’t AirPlay-compatible, you can use an HDMI cable and a Lightning-to-HDMI adapter.

A Lightning-to-HDMI adapter is a dongle that attaches your iPhone to an HDMI cable, which connects to your TV. The adapter costs around 40 on Amazon, and you’ll also need to buy an HDMI cable if you don’t have one already.

Connect the Lightning end of the cable to your iPhone.

Plug one end of your HDMI cable into the other end of the adapter.

Connect the other end of the HDMI cable to your Samsung TV.

samsung, miracast, cast, phone

Switch the input of the television to the corresponding HDMI channel.

Begin playing the desired media on your phone to see it on your TV.

How to change AirPlay settings on your Samsung TV

Using your TV remote, go to Settings and select General.

Choose Apple AirPlay Settings from the menu.

From here, choose one or more of the following options to make adjustments:

  • AirPlay: This allows you to turn your TV’s AirPlay feature on, which only needs to be done the first time you use AirPlay. You can also turn AirPlay off.
  • Subtitles and Captioning: This setting not only allows you to turn subtitles for your selected media on and off, it also lets you change the size, font, and color of the subtitles.
  • About AirPlay: Open this menu if you want to make sure you’re running the latest version of AirPlay, or to find information about your current software.
  • Require Code: When you first start using AirPlay, anybody on your Wi-Fi network with a compatible device can connect and mirror to your TV. If you want to prevent this for any reason, you can use this setting to create a passcode users need to enter before they can project anything to your TV.

How to use Miracast to mirror your device’s screen wirelessly on your TV—even 4K

After the Wi-Fi Alliance announced the finalization of the Miracast wireless display standard at CES 2013, a plethora of Miracast-enabled devices and receivers followed, and include newer devices like Microsoft’s Surface Pro (2017) and Amazon’s Fire TV stick. But while Miracast continues to be developed—as of July 2017, Miracast hardware will support HD and 4K streaming, for example—it’s also lost some support to competing technologies. Keep reading to figure out how Miracast could work for you.

How Miracast works

Users can wirelessly mirror the display of their Miracast-certified phone, tablet, or PC to any Miracast-capable receiver like a TV, projector, or monitor. What you see on your device is exactly what will be displayed on your TV (albeit with a smidgen of input lag). You can also use a Miracast display as an extended PC monitor.

At the core of this technology is the Wi-Fi Direct standard, which allows for point-to-point connections between devices without the use of a router. From there, Miracast adds a vendor-neutral wrapper that originally supported the streaming of up to 1080p video and 5.1 surround sound. Miracast also secures that connection using WPA2 encryption, so protected content like Blu-ray and Netflix videos can flow freely across it.

The peer-to-peer nature of a Miracast connection means mirroring can be done securely and without an internet connection. The apps and content are streamed directly from your device, instead of through an internet service, as with Google’s Chromecast.

For businesses, Miracast could make video conferencing, slide shows, and group product design that much easier. For home users, Miracast offers a great way to stream high-definition videos and photos to your television.

It works great, if all your hardware and software are on the same page. There’s the rub.

What you need to use Miracast (it’s complicated)

Of course, there’s a catch if you want to cut out streaming middlemen: Both the device you have and the device you want to display to must support Miracast.

samsung, miracast, cast, phone

For the device whose screen you want to mirror, support for Miracast requires three things: wireless chipset support, operating system support, and driver support. If your device doesn’t meet all three of these requirements then you’ll have to buy a Miracast adapter and upgrade your operating system (more on that below). Miracast source adapters are often bundled with Miracast receivers like Actiontec’s ScreenBeam kit.

ACTIONTEC Screenbeam MINi2 Wireless Display Kit for Win 7/8

On the software side, Miracast is supported in Windows 8.1 and Windows 10. Older Windows versions can be made to support Miracast through third-party apps. Linux distros have access to wireless display support through Intel’s open-source Wireless Display Software for Linux OS. However, we recommend skipping all these minefields and using an operating system that supports Miracast natively.

Android supported Miracast in Android 4.2 (KitKat) and Android 5 (Lollipop). However, Google dropped native Miracast support in Android 6 (Marshmallow) and later. If you want to mirror the display from a newer Android phone or tablet, you’ll need to do so via Chromecast.

Neither Apple’s OS X nor iOS support Miracast. Instead, Apple has opted for its own AirPlay technology, which requires an Apple TV to mirror the display wirelessly on a television screen.

Among Windows hardware, laptops and tablets starting with Intel’s fourth- and fifth-generation Core processors and Intel’s own 7260 wireless chip supported Miracast, but the Intel technology underlying that support, WiDi, has been discontinued in favor of the Windows 8.1/10 support mentioned above. AMD Wireless Display has supported it in laptops starting with third- and fourth-generation APUs.

Still unsure whether your device supports Miracast? You can always check the box or online product description for a mention of “Miracast-certified,” or just follow the steps in the “How to use Miracast” section below to see if the option exists in your device’s settings menu.

Miracast receivers and adapters

The receiver side of the equation can also be complicated. Smart-TV manufacturers like Sony, LG, Samsung, Toshiba, Panasonic added Miracast to their high-end television sets some years ago, as did certain projector manufacturers, but that doesn’t mean Miracast is built into the TV or monitor you own now.

Microsoft Wireless Display Adapter

Amazon’s Fire TV devices and Roku players support screen mirroring through Miracast. Note that Fire TV devices don’t officially support mirroring from Windows, meaning you may have trouble sharing the screen from a PC to Amazon’s streaming devices.

Actiontec ScreenBeam Mini2 Wireless Display Receiver(SBWD60A01)

We recommend picking a first-party adapter if you can find one. For example, if you wanted to screen-beam from a Microsoft Surface Pro, you’d be best off with Microsoft’s adapter. That’s not to say third-party adapters are bad, but troubleshooting is easier when you’re working with devices from the same company.

Setup for any of these adapters is simple: Just plug the adapter into any open HDMI input port on your TV, projector, or monitor, then plug the small USB cable coming from the side of the device into the TV or an outlet. These USB cables don’t actually transfer any data; they’re there just to provide power to the adapter.

How to use Miracast

Now that you’ve got a Miracast-capable device, power on your display, and switch the appropriate input if you’re using a streaming box or adapter.

Some adapters, like Microsoft’s, will require you to press a power button located on the physical dongle. It may take up to 90 seconds for the adapter to finish booting up, but most are faster. Your TV will then display a splash screen asking you to connect a device.

On streaming devices, you may have to navigate through some menus to enable mirroring. On the Fire TV, for instance, you must long-press the Home button, then select “Mirroring.” On Roku devices running OS 7.6, you’ll find the Screen Mirroring option under Settings System. (This is no longer required on Roku devices running OS 7.7, which rolled out in August 2017.)

Now it’s time to head over to your source device and connect it to your adapter.

In Windows 10, screen mirroring lives inside the quick settings section of the Action Center. Click the speech bubble icon on the far-right side of the task bar to launch Action Center, then click the Connect button near the bottom of the screen. (If you don’t see the button, click Expand right above the quick settings section.)

A list of available Miracast display devices should appear within this menu. Click the device name to begin the connection process.

Depending on your display device, you may have to enter a PIN to verify that the connection is secure, or complete the connection on your display device. Roku, for instance, provides a mini-menu to approve the connection on a one-time or permanent basis.

After a moment, your display device will either mirror your PC or act as an extended monitor. Selecting Change projection mode in the Windows 10 Connect menu lets you choose between mirroring, monitor extension, and disabling your primary PC display. (One word of caution for multi-monitor setups: Choosing to duplicate your PC display will cause all of your monitors to show the same screen. If you want to mirror only your primary monitor, select Second-Screen Only.)

If you have an older Android device that still supports Miracast, you’ll need to go to the Settings menu, tap Display, and then tap Wireless display. At the top of this page, toggle “Wireless display” to ON and it will scan for nearby Miracast devices. After a minute, the name of your Miracast adapter should pop up. Tap it and either your device will connect, or you’ll be prompted for the PIN code display on your TV or projector by the Miracast adapter. After you connect to the adapter your screen will be mirrored onto your display.

A final note: One issue you may encounter when mirroring to a TV is overscan. Many TVs are set to overscan their HDMI inputs, which will make the image appear zoomed-in. To fix this you’ll need to go into your TV’s options menu and set it to display on a dot-by-dot basis, rather than the stretch or zoom settings. Some Miracast adapters—again, like Microsoft’s—come with an app that can use the adapter itself to change the overscan level.

This story was updated on July 28 and August 16, 2017 with new information about Miracast’s 4K capabilities, and current hardware and software support.
