Miracast

High-definition content sharing on
Wi-Fi® devices everywhere

Wi-Fi CERTIFIED Miracast™ enables seamless display of multimedia content between Miracast® devices. Miracast allows users to wirelessly share multimedia, including high-resolution pictures and high-definition (HD) video content between Wi-Fi devices, even if a Wi-Fi network is not available.

Miracast:

  • Projects content from mobile devices to automobile infotainment systems
  • Shares a laptop screen with a conference room projector in real-time
  • Streams HD and 4K Ultra HD movies from a tablet to an HD television
  • Shows pictures from a smartphone, computer, or tablet to a large screen television
  • Support a wide range of audio/video formats to extend battery life in mobile devices

Miracast also supports premium content—such as Blu-ray feature films, live television shows and sports, and other copy-protected premium content—allowing you to watch what you want, where you want.

Standards-based Miracast advances life without wires

Miracast is an industry-wide solution, allowing technology to work across device types and vendors. Connections are easy to set up and use since Miracast devices choose the appropriate settings automatically. Miracast can connect two devices using network infrastructure or Wi-Fi Direct®. When content to be shared is stored on a Miracast-certified device, such as a smartphone to an automobile infotainment display, a Wi-Fi network connection is not required.

Only devices marked Wi-Fi CERTIFIED Miracast have been certified by Wi-Fi Alliance® to work well with other Wi-Fi CERTIFIED™ devices, employ the latest security protections, and deliver a high-quality user experience.

  • Are Wi-Fi CERTIFIED products protected by security?

    As of July 1, 2020, all new Wi-Fi CERTIFIED devices require WPA3. The only way to be sure that a product meets the latest security standards is to purchase only Wi-Fi CERTIFIED products.

  • How does Wi-Fi Alliance help ensure product compatibility and a good user experience for certified products?

    Compatibility and quality are achieved through testing of Wi-Fi products. Consumers should always look for the Wi-Fi CERTIFIED logo to ensure the best user experience possible.

  • What has changed in Miracast since its original release?

    New enhancements focus on high-definition (HD) content, increased performance, and better battery life for Miracast devices.

  • Is a Wi-Fi connection needed to stream a video from the internet?

    Miracast is unique to other wireless display solutions in that a direct peer-to-peer connection between two devices may be formed to share content residing on the source device, without the need for a Wi-Fi network. If streaming content from the internet, a network connection is required.

  • Does Miracast support devices like wireless speakers? (audio only)

    Audio-only devices are not part of the Miracast certification program.

  • How does Miracast protect premium content?

    Miracast provides industry-standard protection of premium content through support of High-bandwidth Digital Content Protection (HDCP). HDCP is a wireless adaptation of the same trusted content protection mechanisms widely used for cabled interfaces, providing diversity in premium content options. This feature is designed to protect the digital rights of content owners and to encourage their efforts to make their content available.

  • What formats does Miracast support?

    Miracast supports many commonly used audio/video format.  For a complete list, download the Miracast Technical Overview.

  • How is Miracast related to Wi-Fi Direct?

    Wi-Fi Direct allows devices to connect directly to each other, without the need for a Wi-Fi access point (AP). It simply requires the push of a button or the entry of a PIN. Wi-Fi Direct allows source and display devices to discover one another and provides the underlying device-to-device connectivity for Miracast. Miracast builds upon Wi-Fi Direct with mechanisms to negotiate video capabilities, setup content protection (if needed), stream content, and maintain the video session.

  • What features does Miracast certification test?

    Miracast certification includes testing for audio/video (A/V) latency, quality, and synchronization offset. Testing ensures that devices operate across vendors, provide simplified discovery and setup, meet the minimum display resolution requirement, and implement content protection (when implemented). Miracast devices are also tested for implementation of WPA2™ security. Wi-Fi Alliance members may view details on certification testing in the Wi-Fi CERTIFIED Miracast Test Plan.

  • Must both the content source and display be Miracast devices?

    Both the display and the source devices must be Miracast certified. Miracast may be used on devices without embedded Wi-Fi capability by using a Miracast-certified adapter that supports an interface such as High-Definition Multimedia Interface (HDMI) or Universal Serial Bus (USB).

  • What types of equipment are tested?

    Miracast certification is available for video-capable devices such as TVs, handsets, tablets, laptops, set-top boxes, cameras, and projectors.

  • What is the difference between Miracast and Wi-Fi Display?

    Miracast is the brand for the certification program operated by Wi-Fi Alliance. Devices that pass this certification testing can be referred to as “Wi-Fi CERTIFIED Miracast™ devices” or “Miracast® devices”. Miracast certification is based on the Wi-Fi Alliance Wi-Fi Display Technical Specification. This is the underlying specification developed by Wi-Fi Alliance members, and is copyrighted and owned by Wi-Fi Alliance.

  • How do I activate TDLS?

    Two Wi-Fi CERTIFIED TDLS devices will automatically form a direct connection after linking to the Wi-Fi network.  No user interaction is required.

The best Miracast and screen-mirroring devices in 2021

You'll want one of the best Miracast or screen-mirroring devices if streaming the contents of your phone, tablet or computer to a TV is your goal. While the best streaming devices can deliver content from popular streaming services, a Miracast gadget will allow you to display whatever you want on a TV screen, whether it’s an obscure video app, a selection of photos or an office presentation. The technology is a little dated, but it’s still arguably quite useful.

Truthfully, though, the best Miracast devices have been a little stagnant over the past few years. The technology hasn’t gotten markedly better, and what worked a few years ago still works fine now. Miracast is also no longer the only game in town when it comes to screen-mirroring protocols. If you have an Android device, Google Cast works much better — as does AirPlay, if you prefer Apple gadgets.

As such, I’ve made a short list of three different devices for screen mirroring protocols. It includes our best Miracast gadget recommendation, as well as devices you can use for better screen-mirroring experiences on Android and Apple. (Miracast is still arguably your best bet for Windows PCs.)

What are the best Miracast and screen-mirroring devices?

The best Miracast and screen-mirroring devices don’t make up a very long list. As stated above, Miracast isn’t a perfect streaming protocol at the best of times. The fact that it’s pretty easy to produce Miracast receivers means that there are a lot of second-rate products out there. Lots of devices support Miracast protocols, from Rokus to Amazon Fire TVs, but for my money, I’ve only ever found one that worked as it was supposed to. That’s the Microsoft Wireless Display Adapter. You plug the gadget into a TV, where it receives a Miracast signal from your phone or computer. That’s all it does, but it works properly, and that’s more than you can say for many Miracast receivers.

If you’re not committed to Miracast as your screen mirroring protocol, other companies have made better ones. Take Google, for example, with its Google Cast functionality. It works just like Miracast, and you can mirror content from either an Android device or a Chrome browser. You can use the Google Chromecast as a receiver. The regular Chromecast works fine if you intend to mirror at 1080p; higher resolutions will require a Google Chromecast Ultra instead.

On the other hand, if you fall on the Apple side of the spectrum, you can pick up an Apple TV and use the AirPlay mirroring protocol. AirPlay is compatible with Macbooks and iOS devices, and works the same way as any other mirroring service. An Apple TV can be particularly useful for Macbook owners, since Miracast works only with Windows PCs and Android devices.

The best Miracast and screen-mirroring devices you can buy today

1. Microsoft Wireless Display Adapter

For Windows Devices

Screen Mirroring Protocol: Miracast | Size: 3.5 x 0.9 x 0.4 inches | Weight: 1.2 oz

Works almost perfectly with both Android and Windows devices

Trivially easy to set up and use

Fantastic audiovisual quality

Short, unremovable power cord

Expensive

Miracast is a technology that allows Android and Windows devices to cast content to TV screens. Most Miracast receivers range from terrible to passable, but the Microsoft Wireless Display Adapter actually works the way it's supposed to. The device is a small HDMI stick with nearly perfect wireless mirroring. Whether you need to stream music, videos, photos, lightweight games or productivity apps, the Wireless Display Adapter can do so with no lag. Simply plug it in, connect your PC or Android device, and see your content on the big screen. That's all the device does, and all it needs to do.

Bear in mind that since Miracast works only with Windows PCs and Android devices, this adapter won’t do you any good if you have a Mac OS computer or an iOS phone. There are solutions for those devices further down on this page, however.

2. Google Chromecast

For Android Devices

Screen Mirroring Protocol: Google Cast | Size: 2.0 x 2.0 x 0.5 inches | Weight: 1.4 oz

Fast performance

Inexpensive

Intuitive interface

Boring, stripped-down design

No significant improvements over second gen

Android devices can take advantage of Google Cast: Google's proprietary screen-mirroring protocol. This broadcasts whatever's on your phone or tablet's screen onto your TV with very little lag or quality loss. While many devices offer Google Cast functionality, the cheapest and easiest is the Chromecast, which costs very little and uses your existing mobile device or computer as a remote control. Google's standard Chromecast can broadcast content at 1080p, while its more expensive Ultra variant can handle 4K media.

While Google Cast works best with Android phones and tablets, you can use it with computers as well. If you use Google’s Chrome browser, you can “tab cast,” or mirror whatever you have open in a Chrome tab to your television. This feature isn’t as rock solid as Google Cast from phones, but it’s still a convenient option for those who want to get the most out of their Chromecasts.

3. Apple TV

For Apple Users

Screen Mirroring Protocol: AirPlay | Size: 3.9 x 3.9 x 1.4 inches | Weight: 15.0 oz

Gorgeous, intelligent interface

Lots of great content

Smart Siri integration

Expensive

Subpar touch controls

AirPlay is one of the oldest and most reliable screen-mirroring protocols. Using an iOS mobile device or a Mac computer, users can mirror their displays on an Apple TV. The setup and activation are essentially foolproof, and the streaming quality for music, photos and video is excellent. Apple TV is also a full-featured set-top box that runs apps for most major streaming sites and plays movies, music and podcasts directly from iTunes. In addition, the Apple TV boasts a sophisticated search thanks to its Siri voice assistant and an admirable selection of both core and casual games.

Like many streaming devices, the Apple TV comes in both 1080p and 4K flavors. The 4K variant is quite expensive, so it’s worth considering how often you mirror content at full HD vs. quad HD or UHD resolutions.

How to choose the best Miracast or screen-mirroring device for you

The best Miracast or screen-mirroring device depends on the gadgets you already own. Simply put: If you plan to stream from a Windows PC, get the Microsoft Wireless Display Adapter. If you plan to stream from an Android device, get the Google Chromecast. If you plan to stream from a Mac OS or iOS device, get an Apple TV. Most screen-mirroring protocols are not cross-compatible, so if you don’t buy the appropriate receiver, you could find yourself staring down a $50 paperweight.

Just bear in mind that when it comes to Google and Apple devices, you have two choices apiece. A regular Google Chromecast or a regular Apple TV can support resolutions of up to 1080p. If you’re mirroring from a very powerful device, you might want a Google Chromecast Ultra or an Apple TV 4K. These streaming devices support resolutions up to 4K. Just bear in mind that you’ll need a pretty strong Internet connection to mirror high-res content reliably.

How we test Miracast and screen-mirroring devices

Testing the best Miracast and screen-mirroring devices is pretty straightforward. We hook up a receiver to a TV, then see how reliably it mirrors content. We test photos, music, videos, office documents and even video games — not necessarily because each one represents a realistic scenario, but to see just how reliable each device is when pushed up against its limits.

We test Miracast devices with Windows PCs and Android phones, Google Cast devices with Android phones and Chrome browsers, and AirPlay devices with Macbooks and iPhones. Each receiver has to prove its worth on both a home network and an office network, since screen mirroring has some productivity applications as well. In home testing cases, we’re particularly interested in how video mirroring stacks up to native apps on streaming devices.

Truthfully, though, testing Miracast and screen-mirroring devices is a pretty simple process, since the receivers don’t have many moving parts. If they work well, you’ll know within half an hour — and if they work poorly, you’ll know much quicker than that.

Miracast

Miracast is a standard for wireless connections from sending devices (such as laptops, tablets, or smartphones) to display receivers (such as TVs, monitors, or projectors), introduced in 2012 by the Wi-Fi Alliance. It can roughly be described as "HDMI over Wi-Fi", replacing the cable from the device to the display.[1]

The Wi-Fi Alliance launched the Miracast certification program at the end of 2012.[2] Devices that are Miracast-certified can communicate with each other, regardless of manufacturer. Adapters became available that may be plugged either into HDMI or USB ports, allowing devices without built-in Miracast support to connect via Miracast.[citation needed] In 2013, Nvidia announced support for Miracast.[3]

Miracast employs the peer-to-peerWi-Fi Direct standard. It allows sending up to 1080p HD video (H.264 codec) and 5.1 surround sound (AAC and AC3 are optional codecs, mandated codec is linear pulse-code modulation – 16 bits 48 kHz 2 channels).[4] The connection is created via WPS and therefore is secured with WPA2. IPv4 is used on the Internet layer. On the transport layer, TCP or UDP are used. On the application layer, the stream is initiated and controlled via RTSP, RTP for the data transfer.[5][6][7][8]

Devices[edit]

The Wi-Fi Alliance maintains a list of certified devices, which numbered over 6,700 as of 9 March 2017[update].[9]

Nvidia announced support in 2012 for their Tegra 3 platform,[10] and Freescale Semiconductor, Texas Instruments, Qualcomm, Marvell Technology Group and other chip vendors have also announced their plans to support it.[11] Actiontec Electronics also supports Miracast with its line of ScreenBeam products.[12]

Both devices (the sender and the receiver) need to be Miracast certified for the technology to work. However, to stream music and movies to a non-certified device, Miracast adapters are available that plug into HDMI or USB ports.[13]

On 29 October 2012, Google announced that Android version 4.2+ (from an updated version of Jelly Bean) supports the Miracast wireless display standard, and by default have it integrated.[14] With Android 6.0 Marshmallow, released in 2015, Miracast support was dropped.[15] Despite this, there are still Miracast apps for Android available.[16]

As of 8 January 2013, the LGNexus 4 and Sony's Xperia Z, ZL, T and V officially supported the function,[17][18] as did HTC One, Motorola in their Droid Maxx & Ultra flagships, and Samsung in its Galaxy S III and Galaxy Note II under the moniker AllShare Cast.[19] The Galaxy S4 uses Samsung Link for its implementation.[20]

In October 2013, BlackBerry released its 10.2.1 update to most of the existing BlackBerry 10 devices available at that time. As of March 2015, the BlackBerry Q10, Q5, Z30, and later models support Miracast streaming; the BlackBerry Z10 does not support Miracast, due to hardware limitations.[21]

In April 2013, Rockchip unveiled a Miracast adapter powered by the RK2928.[22]

Microsoft also added support for Miracast in Windows 8.1 (announced in June 2013) and Windows 10.[23][24] This functionality first became available in the Windows 8.1 Preview, and is available on hardware with supported Miracast drivers from hardware (GPU) manufacturers such as those listed above.

The WDTV Live Streaming Media Player added Miracast support with firmware version 2.02.32

The Amazon Fire TV Stick, which started shipping on 19 November 2014, also supports Miracast.

The Roku streaming stick and Roku TV started providing support for Miracast starting October 2014.[25]

On 28 July 2013, Google announced the availability of the Chromecast powered by a Marvell DE3005-A1,[26] but despite the similarity in name and Google's early support of Miracast in Android, the Chromecast does not support Miracast.

On 23 September 2014, Microsoft announced the Microsoft Wireless Display Adaptor, a USB-powered HDMI dongle for high definition televisions.[27][28]

As of late April 2016, the Ubuntu Touch-powered Meizu Pro 5 supported Miracast in OTA-11.[29]

Functionality[edit]

The technology was promoted to work across devices, regardless of brand. Miracast devices negotiate settings for each connection, which simplifies the process for the users. In particular, it obviates having to worry about format or codec details.[30] Miracast is "effectively a wireless HDMI cable, copying everything from one screen to another using the H.264 codec and its own digital rights management (DRM) layer emulating the HDMI system". The Wi-Fi Alliance suggested that Miracast could also be used by a set-top box wanting to stream content to a TV or tablet.

Types of media streamed[edit]

Miracast can stream videos that are in 1080p, media with DRM such as DVDs, as well as protected premium content streaming, enabling devices to stream feature films and other copy-protected materials. This is accomplished by using a Wi-Fi version of the same trusted content mechanisms used on cable-based HDMI and DisplayPort connections.[31]

Display resolution[edit]

  • 27 Consumer Electronics Association (CEA) formats, from 640 x 480 up to 4096 x 2160 pixels, and from 24 to 60 frames per second (fps)
  • 34 Video Electronics Standards Association (VESA) formats, from 800 x 600 up to 2560 x 1600 pixels, and from 30 to 60 fps
  • 12 handheld formats, from 640 x 360 up to 960 x 540 pixels, and from 30 to 60 fps
  • Mandatory: 1280 x 720p30 (HD)
  • Optional: 3840 x 2160p60 (4K Ultra HD)[32]

Video[edit]

Mandatory: ITU-T H.264 (Advanced Video Coding [AVC]) for HD and Ultra HD video; supports several profiles in transcoding and non-transcoding modes, including Constrained Baseline Profile (CBP), at levels ranging from 3.1 to 5.2

Optional: ITU-T H.265 (High-Efficiency Video Coding [HEVC]) for HD and Ultra HD video; supports several profiles in transcoding and non-transcoding modes, including Main Profile, Main 444, SCC-8 bit 444, Main 444 10, at levels ranging from 3.1 to 5.1

Audio[edit]

Mandated audio codec: Linear Pulse-Code Modulation (LPCM) 16 bits, 48 kHz sampling, 2 channels

Optional audio codecs, including:

  • LPCM mode 16 bits, 44.1 kHz sampling, 2 channels
  • Advanced Audio Coding (AAC) modes
  • Dolby Advanced Codec 3 (AC3) modes
  • E-AC-3
  • Dolby TrueHD, Dolby MAT modes
  • DTS-HD mode
  • MPEG-4 AAC and MPEG-H 3D Audio modes
  • AAC-ELDv2

Version history[edit]

Version Date Remarks[33]
1.0 2012-08-24 Public release version
1.1 2014-04-24 Public release for HDCPv2.2 updates.
2.0 2017-04-21 Release 2 final version.
2.1 2017-07-31 Corrected heading errors in sections 4.3 and 4.4.

Removed references to Miracast.

Issues[edit]

Certification does not mandate a maximum latency (i.e. the time between the display of pictures on the source and display of the mirrored image on the sync display).

Although touted as a major feature of Android Kit Kat, support in Android was dropped in 2015, and Computerworld observed that "Miracast never quite caught on as a standard".[15]

OS support[edit]

Windows[edit]

The latest Windows 10 release supports Miracast receiving along with User Input Back Channel (UIBC) support to allow for human interface devices (touch screens, mouse, keyboard) to also have wireless connectivity (provided the host hardware also supports this). Windows 8.1 supports broadcasting/sending the screen via Miracast. Miracast is also built into Windows Phone 8.1.[34] Developers can also implement Miracast on top of the built-in Wi-Fi Direct support in Windows 7 and Windows 8.[35] Another way to support Miracast in Windows is with Intel's proprietary WiDi (v3.5 or higher). A software-based Miracast receiver for Windows 8.1, AirServer Universal, was made available on 31 October 2014 by App Dynamic.[36]

iOS and macOS[edit]

Apple does not support the Miracast standard on iOS or macOS, instead using its own proprietary peer-to-peer AirPlay protocol.

Linux desktop[edit]

GNOME Network Displays[37] is an experimental Miracast implementation for Linux. Despite its name, it should work on all Linux desktop environments. It provides a GUI and should work out of the box for most Miracast devices.

MiracleCast[38] provides early support for Miracast, but is not tied to that single protocol.

Wireless Display Software for Linux OS (WDS)[39] initial Miracast support, developed by Intel.

Android[edit]

Google currently does not support the Miracast standard on the stock version of Android in version 6.0 Marshmallow and later. However, some manufacturers of Android devices step in and support Miracast through their software on custom versions of Android (for example: Smart View on Samsung's One UI, Cast on Xiaomi's MIUI, Screencast on Oppo's ColorOS, Wireless Projection on Huawei's EMUI, HTC Sense, LG UX, Asus ZenUI, Sony Xperia devices, OnePlus's OxygenOS etc.).[40] The performance quality of the streamed video is dependent on the Android device's processor.

Miracast support had been built into stock Android with version 4.2 (Android Jelly Bean)[41] and starting with Android 4.4, devices could be certified to the Wi-Fi Alliance Display Specification as Miracast compatible.,[42] but support was dropped with Android 6.0 Marshmallow in 2015 in favor of Google's own proprietary Google Cast protocol.[15]

Nokia devices, which ran a near-stock version of Android, originally did not support Miracast. However, Nokia 7 Plus, 8, 8 Sirocco, and 8.1 smartphones that have been upgraded to Android 9 or 10 are able to support Miracast, after enabling Wireless Display Certification in Developer Options. Devices such as Nokia 2.3, 2.4, 3.4, 5.4, and 8.3 5G have Miracast support enabled by default.[43]

BlackBerry OS[edit]

Miracast is also supported by BlackBerry OS from version 10.2.1 onwards.

Hi,

 

Thank you for writing to Microsoft Community Forums.

 

You can use any normal Wi-Fi adapter and it will help you in casting the screen. A Wi-Fi adapter comes with a USB port and when it is connected to a Desktop, it acts like a Wi-Fi modem. A modem is used to send and receive signals and the same way a Wi-Fi adapter can be used to send and receive signals.

 

You can use your favorite search engine, search for a Wi-Fi adapter, and purchase it from any E-commerce website or a physical store.

 

Regards,

Nikhar Khare

Thanks for your feedback.

This reply is...incomplete at best, confusing, and just plain wrong.

Miracast support requires the driver to be NDIS version 6.3 or higher. Getting this info from manufacturers can be difficult/impossible.

Devices w/ the Realtek chipset RTL88xx seem to be good candidates.

>it acts like a Wi-Fi modem. A modem is used to send and receive signals and the same way a Wi-Fi adapter can be used to send and receive signals.

**** does that even mean? No, no modem is involved. You need a wifi adapter, period*.

Okay, technically you could use ethernet, if Miracast over Infrastructure was supported/configured...
