Screen Casting vs Screen Mirroring: What’s The Difference?

The lives of Gen Z kids are seamlessly intertwined with multiple screens, from smartphones and tablets to laptops and smart TVs. As we juggle these devices, the ability to share content across different screens has become a necessity. Enter screen casting and screen mirroring —two technologies that allow you to transmit data from one device to another wirelessly, yet they are different from each other.

Screen casting is designed to stream audio/visual content from your mobile or computer to a compatible streaming device. On the other hand, screen mirroring replicates your entire device’s screen onto the TV. Keep reading to learn more about the differences between screen casting and mirroring.

What is Screen Casting?

Screen casting allows you to stream specific audio or video content from your smartphone, laptop, or other electronic devices to a compatible TV or streaming device. It’s like having a wireless HDMI cable, enabling you to enjoy your favorite web series, movies, or videos on a bigger screen. Screen casters frequently record their camera feed as well as what’s on their screens to give their videos a personal touch.

If you’ve ever watched a video-streaming site like YouTube with the host’s screen overlayed, you’ve seen a screencast. Furthermore, many businesses use pre-recorded screencast presentations for recruit onboarding, employee training, and client webinars.

What is Screen Mirroring?

Screen Mirroring takes things further by replicating your entire mobile device’s screen onto the TV. Imagine your phone’s display, including apps, notifications, and even your home screen, being projected onto the TV in real time. This feature is handy when sharing presentations and photos or playing mobile games on a larger canvas.

For instance, you could mirror your phone’s screen to a smart TV to showcase vacation photos to your family or friends, allowing them to relive those precious moments on a bigger screen. Alternatively, you could mirror your laptop’s screen to a TV and show a presentation using secure video conferencing platforms.

Screen Casting vs Screen Mirroring: Know the Differences

Screen Casting and Screen Mirroring are two popular ways to wirelessly share content from your smartphone or tablet to a larger display like a TV. While they may sound similar, there’s a subtle yet crucial difference between them.

Screen casting allows you to stream content from one device to another. On the other hand, screen mirroring replicates your entire screen onto the other device. So, let’s examine a few of these differences in detail to help you better understand them.

How Does Screen Casting & Screen Mirroring Work?

Screen casting establishes a wireless connection between the source device (e.g., smartphone, tablet) and the receiving device (e.g., smart TV, streaming stick). The source device encodes and transmits the audio/video data over the wireless network, while the receiving device decodes and displays the content on its screen.

On the other hand, screen mirroring imitates your entire device’s screen, including the user interface, apps, notifications, and even the home screen, onto the larger display. It captures the screen in real time and transmits the captured frames wirelessly to the receiving device, displaying the mirrored content.

Devices Compatibility

Screen casting has gained widespread support across various platforms and devices. Smart TVs, streaming devices like Chromecast, Roku, and Apple TV, and popular content streaming apps like Netflix, Hulu, and YouTube often support screen casting natively or through dedicated apps.

Screen mirroring is also widely supported by smartphones, tablets, and smart TVs from major manufacturers like Samsung, LG, Sony, and others. Many devices come with built-in screen mirroring capabilities or support it through software updates or dedicated apps.

Technical Variances

Screen casting typically uses dedicated protocols like Google Cast, AirPlay, or Miracast, which are optimized for efficiently streaming audio/video content. These protocols often employ advanced codecs, adaptive bitrate streaming, and other techniques to ensure smooth playback and minimize latency.

In contrast, screen mirroring may rely on different technologies, like Miracast or proprietary solutions from device manufacturers. These technologies are designed to mirror the entire screen in real-time, accounting for various screen resolutions, aspect ratios, and input methods (e.g., touch or mouse).

Performance & Quality

Screen casting generally offers better performance and quality when streaming audio/video content, as the protocols and codecs used are optimized specifically for that purpose. They prioritize smooth playback, reduced latency, and efficient bandwidth usage, ensuring a high-quality viewing experience on a larger screen.

Screen mirroring, while capable of displaying high-quality visuals, may experience latency or performance issues, especially with graphically intensive applications or games. Since it needs to capture and transmit the entire screen in real-time, performance can be affected by factors like network bandwidth, processing power, and the complexity of the mirrored content.

Security Concerns

When screen casting, the content being streamed is typically from trusted sources and apps, reducing potential security risks. For example, when casting a Netflix show, only the video and audio data from the Netflix app is transmitted, minimizing the chances of unintentionally exposing sensitive information.

However, with screen mirroring, as your entire device’s screen is replicated on the larger display, there is a higher risk of unintentionally sharing sensitive information or notifications that may appear on your device’s screen. However, you can invest in platforms like Zoapi, which offers encrypted video conferencing to safeguard your data.


Whether you cast or mirror, both technologies offer a seamless and cable-free way to enjoy content from your mobile devices on larger screens. The decision between the two ultimately depends on your specific needs and preferences. Casting is the way to go if you want to enjoy specific audio or video content without interruptions. However, mirroring is better if you need to share your entire device’s interface or play mobile games on a larger screen.
