To better understand what screen mirroring is, you have to know what it isn’t. 

1. Online meeting/video conferencing software

Online meeting software, desktop sharing software, or video conferencing software, such as GoToMeeting or, is not the same as screen mirroring. Screen mirroring is a “localized” action, which means that the sending and receiving devices must be on the same network. There is no need for an internet connection.

Screen data never crosses the internet because connections are point-to-point and remain on the local network. For viewing purposes, both devices are usually placed in the same room. There are some exceptions where the devices do not have to be connected to the same network. More information on this can be found further down.

2. Media streaming

Screen mirroring is not the same as media streaming. The continuous playback of an audio or video file is referred to as media streaming. On a daily basis, many people consume media. Have you ever heard of Netflix or YouTube? That’s what media streaming is. However, media streaming can be as simple as sending an audio or video file from your computer to an external receiver like an Apple TV/Samsung Tv.

If you only need to send an audio or video file to the big screen, streaming is ideal. For presenting and collaborating, screen mirroring is preferable.

3. Cables, adapters, and dongles

Some people define screen mirroring as including physical connections such as HDMI, VGA, and various other cables and dongles. As the world transitions to wireless technology, these methods are becoming increasingly obsolete. Screen mirroring is a completely wireless act for the purposes of this article.


Screen mirroring sends the media you’re watching on your smartphone to your TV via Wi-Fi. Though an HDMI cable can be used, it is far more convenient to mirror to the TV wirelessly.

The key point to remember here is that both devices must be connected to the same network for this to work.


The primary distinction between the two is that mirroring duplicates your mobile screen on a larger screen. Casting, on the other hand, sends any type of content to your fire TV without playing it on the device from which you are casting.

Home entertainment

Consumers can mirror and stream music, movies, videos, photos, mobile gameplay, and other content from their devices to TVs and displays that have a compatible receiver. AirParrot and Reflector are two popular consumer screen mirroring applications.


You can benefit from screen mirroring in a variety of ways. As an example:

  • You can mirror your photos and videos and watch them on your television.
  • There are no cables required! You can easily share anything you want without the use of wires or cables.
  • Low price. It is not expensive to display your mobile screen on the television.
  • You and your friends can play multiplayer games on the TV.
  • Mirroring movies and films from your smartphone transforms your living room into a theater.


To screen the mirror, the sending and receiving devices must be on the same network. However, for security reasons, an organization may require specific devices and receivers on separate networks. For example, to avoid having guest network traffic on the main network, an organization may have a separate network for guests. Guests would be unable to connect to a receiver, such as an Apple TV, as a result of this.

There are a few options for dealing with this issue. Organizations will frequently open specific network ports for local network communication. Multicast or Bonjour Forwarding may also be required in some cases. These steps will enable screen mirroring across networks. This solution, however, is not appropriate for all organizations. Due to security and legal obligations, some organizations are unable to open network ports.

Fortunately, our screen mirroring experts collaborated with these organizations’ high-profile engineering and IT teams to develop technology that allows devices on separate networks to screen mirror without opening network ports or requiring any user information to cross the internet. It simplifies connecting for end users while also keeping networks secure.


The benefits of screen mirroring are too numerous to ignore. Though there are some drawbacks, such as the need to keep the mobile screen on while mirroring the screen, it’s still worth a shot. You can now give it a shot and enjoy sharing your media with your friends and family.


What is required for screen mirroring?

Screen mirroring necessitates the use of two devices: a screen-sending device and a screen-receiving device. A screen mirroring protocol is used by the screen-sending device. There are various screen mirroring protocols. Apple AirPlay on iPhones and Google Cast on Chromebooks are excellent examples of this.
