The Basics

Before you go any further, we should establish the basics of screen mirroring. This section covers what screen mirroring is and popular types of screen mirroring.

What is screen mirroring?

Screen mirroring technology allows you to wirelessly share a device screen to another display in the same space in real time. Screen mirroring requires both a screen-sending device and a screen-receiving device (often called a receiver or media player).

Screen-sending device: This is the device you are mirroring from (the device you want to share to another display). This device can be a phone, tablet or computer. These devices use a proprietary wireless communication protocol like AirPlay, Miracast, Google Cast or other purpose-built screen mirroring software to share content to other devices. You can screen mirror from iPhones, iPads, Android phones and tablets, Chromebooks, Windows PCs, Macs and more.

Screen-receiving device: This is the device you are mirroring to (the device you want to display your shared content on). Common hardware receivers include media players like Apple TV, Chromecast, Amazon Fire TV Stick and Roku; TVs with built-in screen sharing capabilities; and numerous hardware receivers built specifically for various screen mirroring solutions.

Selecting the right screen mirroring solution can be a confusing, time-consuming process. Read the 9 Things You Must Know Before Picking a Screen Mirroring Solution to make the best decision.  

screen sending and screen receiving device

It’s possible to use cables or wired setups like HDMI to share your screen to another display. However, wired screen sharing is an outdated, problematic and costly solution. For the purposes of this guide, screen mirroring is an entirely wireless act.

Read 7 reasons you should look for wireless alternatives to HDMI cables.

Screen mirroring protocols

Many devices have native, built-in screen mirroring protocols that allow data to be wirelessly transmitted from one place to another. A mirroring protocol lets devices screen mirror and stream media to compatible devices or wireless receivers.

AirPlay, Miracast, Google Cast, Smart View and Ditto protocol logosMirroring protocols include:

  • AirPlay, Apple’s proprietary mirroring protocol for Apple products.
  • Google Cast, screen casting developed by Google for Google products.
  • Smart View, Samsung’s mirroring protocol.
  • Miracast, compatible with some Windows and Android devices.
  • SSP, the all-in-one enterprise screen mirroring and streaming protocol used in Ditto. It’s compatible with a wider range of devices than the built-in, native protocols included on Apple, Android and Windows devices.
  • Other protocols, third-party screen mirroring alternatives to native protocols.

The good news: Some of these protocols like AirPlay, Google Cast and Miracast come built-in with most of the devices you already have. This means quick and easy screen mirroring to compatible devices.

The bad news: These protocols are only compatible with devices that use the same protocol. That means you can't, for instance, screen mirror an iPhone to a Windows PC or a Windows Surface Pro to an Apple TV without a third-party screen mirroring solution. They also tend to create a number of problems on your network (detailed in the sections below).

These issues limit screen sharing, especially in collaboration hotspots like schools and businesses. It’s a big reason why more complete, inclusive screen mirroring solutions have become so popular.

It can be confusing to figure out when to use these protocols or when to search for an alternative. We break down when to use each screen mirroring protocol below:

When to use AirPlay

Most Apple devices come equipped with AirPlay. iPhones, iPads, Macs, HomePods and Apple TV all use AirPlay to wirelessly send and receive content.

AirPlay screen mirroringIf you only own Apple devices, you can probably stick with using AirPlay to screen mirror. Here’s what you can screen mirror and stream with AirPlay:

  • Screen mirror iPhone to Apple TV
  • Screen mirror iPhone to Mac*
  • Stream audio from iPhone to HomePod
  • Screen mirror iPad to Mac*
  • Screen mirror iPad to Apple TV
  • Stream audio from iPad to HomePod
  • Screen mirror Mac to Apple TV
  • Stream audio from Mac to HomePod

*AirPlay mirroring iPhone/iPad to Mac is limited to certain devices and only on macOS Monterey.

The problem: Non-Apple devices are not equipped with AirPlay. As mentioned above, people with other device types will not be able to share content wirelessly using AirPlay. Additionally, AirPlay isn’t ideal if you have a complex or secured network like most schools and businesses. AirPlay requires Bonjour and multicast traffic to be allowed on your network.

AirPlay is also limiting when you have separate networks. If you have employees on one network and guests on another, or students and teachers on separate networks, they wont be able to share. The sending and receiving devices must be on the same network. Additionally, AirPlay doesn't provide advanced customization options that allow you to determine how and what you mirror. Other screen mirroring products like Ditto help resolve these issues.

When to use Google Cast

Google Cast is the built-in screen mirroring protocol common on Google devices, Android and Chrome operating systems, and some Google apps. Chromecast built-in is the Google streaming protocol for many smart TVs and media players.

Google Cast screen mirroringGoogle Cast (or Chromecast built-in) is a good option when you just want to mirror your Android phone or Chromebook to your smart TV. However, your smart TV must have Chromecast built-in for this to work.

Here’s what you can screen mirror and stream with Google Cast:

  • Screen mirror Android phone to TV with Chromecast built-in
  • Stream audio from Android phone to Google smart speaker
  • Screen mirror Android tablet to TV with Chromecast built-in
  • Stream audio from Android tablet to Google smart speaker
  • Screen mirror Chromebook to TV with Chromecast built-in
  • Screen mirror from Chrome web browser to Chromecast built-in
  • Stream audio from Chrome web browser to Google smart speaker
  • Casting to a Chromecast device plugged into an HDMI port

If you require security features, look for an alternative to Google Cast. The built-in protocol doesn’t offer vital security features for schools and businesses and connections can’t cross VLANS.

When to use Smart View

Smart View is Samsung’s version of Google Cast. Smart View is an app for your Samsung phone, tablet or laptop that lets you screen mirror to other Samsung devices.

Smart View screen mirroringUse Smart View if you want to mirror your Samsung mobile device or laptop to a Samsung TV or other Samsung display. Do not use Samsung Smart View if you need compatibility with a wider range of devices or if you need a screen mirroring solution that's secure and scalable for heavy usage in places like schools and businesses.

When to use Miracast

Miracast is available on some Windows and Android devices. Use Miracast when you want to screen mirror an Android or Windows device to a Miracast-enabled TV or other display.

Miracast screen mirroringWhile this is an acceptable option for home use, Miracast is not suitable for large organizations due to poor security measures and compatibility limitations.
