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’southward Surface Pro (2017) and Amazon’s Fire Television set stick. But while Miracast continues to exist developed—as of July 2017, Miracast hardware volition support Hard disk and 4K streaming, for example—information technology’southward too lost some support to competing technologies. Go along reading to effigy out how Miracast could work for you.
How Miracast works
Users can wirelessly mirror the brandish 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 volition be displayed on your Television (albeit with a smidgen of input lag). Yous can besides apply a Miracast brandish as an extended PC monitor.
At the core of this engineering science is the Wi-Fi Straight standard, which allows for indicate-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 upward to 1080p video and 5.1 surroundings sound. Miracast also secures that connexion using WPA2 encryption, so protected content similar Blu-ray and Netflix videos can flow freely across information technology.
The peer-to-peer nature of a Miracast connection ways mirroring tin exist done securely and without an internet connectedness. The apps and content are streamed direct from your device, instead of through an cyberspace service, as with Google’s Chromecast.
For businesses, Miracast could brand video conferencing, slide shows, and group production pattern that much easier. For dwelling users, Miracast offers a nifty way to stream loftier-definition videos and photos to your telly.
It works great, if all your hardware and software are on the aforementioned page. There’s the rub.
What yous demand to use Miracast (it’s complicated)
Of course, there’s a catch if you desire to cutting out streaming middlemen: Both the device you have and the device you desire to brandish to must support Miracast.
For the device whose screen you want to mirror, support for Miracast requires iii things: wireless chipset support, operating system back up, 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 beneath). Miracast source adapters are frequently arranged with Miracast receivers like Actiontec’southward ScreenBeam kit.
On the software side, Miracast is supported in Windows viii.1 and Windows 10. Older Windows versions can be fabricated 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. Yet, nosotros recommend skipping all these minefields and using an operating system that supports Miracast natively.
Android supported Miracast in Android 4.2 (KitKat) and Android v (Lollipop). However, Google dropped native Miracast back up in Android 6 (Marshmallow) and later. If y’all want to mirror the display from a newer Android phone or tablet, yous’ll need to practice and then via Chromecast.
Neither Apple’southward Os X nor iOS support Miracast. Instead, Apple has opted for its own AirPlay technology, which requires an Apple Television to mirror the brandish wirelessly on a boob tube screen.
Amidst Windows hardware, laptops and tablets starting with Intel’south fourth- and 5th-generation Cadre processors and Intel’s own 7260 wireless flake 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 only follow the steps in the “How to use Miracast” section below to run into if the selection exists in your device’due south settings menu.
Miracast receivers and adapters
The receiver side of the equation can besides be complicated. Smart-Television set manufacturers like Sony, LG, Samsung, Toshiba, Panasonic added Miracast to their high-end telly sets some years ago, as did certain projector manufacturers, merely that doesn’t mean Miracast is congenital into the Idiot box or monitor you own at present.
Amazon’due south Fire TV devices and Roku players back up screen mirroring through Miracast. Note that Fire Television set devices don’t officially support mirroring from Windows, meaning you may have problem sharing the screen from a PC to Amazon’s streaming devices.
If all else fails, you lot tin can buy a dedicated Miracast receiver dongle, such as the Actiontec ScreenBeam Mini2 receiver or Microsoft’south Wireless Display Adapter are ii choices currently available. Which i you buy largely boils down to whose ecosystem yous prefer.
We recommend picking a first-political party adapter if y’all can find one. For example, if yous wanted to screen-beam from a Microsoft Surface Pro, you’d be best off with Microsoft’s adapter. That’s not to say 3rd-party adapters are bad, only troubleshooting is easier when yous’re working with devices from the same company.
Setup for whatever of these adapters is simple: Just plug the adapter into any open up HDMI input port on your Tv set, projector, or monitor, and so plug the small USB cablevision coming from the side of the device into the Tv or an outlet. These USB cables don’t actually transfer whatever 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 brandish, 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 ability push located on the physical dongle. It may take up to 90 seconds for the adapter to terminate booting up, just virtually are faster. Your Tv set volition then display a splash screen asking you to connect a device.
On streaming devices, you lot may accept to navigate through some menus to enable mirroring. On the Fire TV, for case, you must long-press the Home button, and so select “Mirroring.” On Roku devices running Bone 7.6, you lot’ll notice the Screen Mirroring option under Settings
> System. (This is no longer required on Roku devices running Bone 7.7, which rolled out in Baronial 2017.)
Now it’s fourth dimension to head over to your source device and connect information technology to your adapter.
In Windows x, screen mirroring lives inside the quick settings section of the Action Center. Click the oral communication bubble icon on the far-right side of the job bar to launch Activeness Center, then click the Connect button near the bottom of the screen. (If you don’t come across the push, click Expand right above the quick settings section.)
A list of bachelor Miracast display devices should appear within this carte du jour. Click the device name to brainstorm the connection process.
Depending on your display device, you may accept to enter a PIN to verify that the connectedness is secure, or complete the connection on your brandish device. Roku, for instance, provides a mini-bill of fare to approve the connectedness on a one-time or permanent footing.
After a moment, your brandish device will either mirror your PC or deed as an extended monitor. Selecting Change projection fashion in the Windows 10 Connect menu lets you choose betwixt mirroring, monitor extension, and disabling your primary PC display. (I word of caution for multi-monitor setups: Choosing to duplicate your PC display will cause all of your monitors to testify the aforementioned screen. If you want to mirror only your primary monitor, select 2nd-Screen Only.)
If you have an older Android device that still supports Miracast, you’ll need to become 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 proper name of your Miracast adapter should pop upwards. Tap it and either your device will connect, or y’all’ll be prompted for the PIN code display on your Tv or projector by the Miracast adapter. Afterward y’all 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 paradigm announced zoomed-in. To prepare this yous’ll need to go into your Television receiver’s options carte and gear up it to display on a dot-by-dot basis, rather than the stretch or zoom settings. Some Miracast adapters—again, similar Microsoft’s—come up with an app that can employ the adapter itself to change the overscan level.
