Key Differences, Common Problems, and More


screen mirror and screen casting have become the most common features when it comes to viewing content from a smartphone or laptop on a larger screen like TVs. That being said, both technologies are designed to achieve a common goal of wirelessly projecting content from a smaller screen to a larger screen, but with a different approach.

Simply put, both technologies work in different ways and also have different uses. To make things easier for you, we’ll explain the difference between the two and when to use them. Moreover, we will also talk about common problems and their fixes.

What is screen mirroring
Screen mirroring, as the name suggests, mirrors your phone or laptop display to a TV. This means that what you see on one screen appears exactly on the other screen. For example, if you have accessed your laptop settings, the mirrored screen will show the same.

When is it useful
The first and most important advantage of screen mirroring is that it does not require users to connect both devices (primary and secondary displays) to the same Wi-Fi network. Basically, it does not require any connectivity Wi-Fi because the system creates its own peer-to-peer wireless connection, much like a Wi-Fi hotspot.

So, that makes it useful in case you don’t have Wi-Fi around, but still want to view content on a bigger screen.

What do you need to use screen mirroring
Screen mirroring is a feature that requires compatible and supported devices. So you need to make sure that your TV and main devices (smartphone, tablet or computer) support screen mirroring.

Most modern PCs, laptops, tablets, and TVs come with a built-in screen mirroring feature. However, not all TVs support screen mirroring. If your TV does not support screen mirroring technology, third-party dongles are available in the market.

Common problems with screen mirroring?
Screen mirroring is not that complicated. Once you are sure the devices are compatible. All you have to do is scan, select and mirror. But, there are times when things don’t work properly, so here are some common issues you may encounter while screen mirroring.

Wireless display not showing on smartphones or laptops
In this case, make sure that screen mirroring features such as Miracast, etc. is enabled on primary and secondary devices. Also, if you’re using third-party dongles, make sure they’re properly connected to the TV and turned on.

Screen mirroring is sluggish and sluggish
Screen mirroring may be a bit delayed and lag as it is streamed by the smartphone. It also depends on the capabilities of your main device wireless adapter.

I can’t use my laptop or smartphone during screen mirroring
As mentioned, screen mirroring mirrors the primary display. Thus, both screens will display the same content. This means you can’t use your phone or laptop for anything else. And that’s where screen casting comes in.

What is screen casting?
Screen casting is also the process of projecting content from a smaller screen onto a larger screen, except it doesn’t mirror things like screen mirroring. This means that if you stream something to another screen, the content will only be visible on the TV. It also means that your primary device is free for other things.
For example, if you streamed a show from Amazon Prime, the TV will show you the show and your phone or laptop is still available for other things.

When it is valid
Screen casting requires compatible hardware (Chromecast supported) as well as Wi-Fi connectivity. This method comes in handy when trying to watch a TV series while working or doing something else on your primary device. It’s also useful for streaming games from your laptop or phone to a TV.

How do I use screen casting?
Using Smartphones (Android/iOS): To cast from your phone to the TV, you’ll need a compatible app that supports screen casting. For example, the entire suite of Google apps which includes YouTube, Photos, etc. supports screen casting. Likewise, online streaming apps such as Netflix, Prime, Apple TV+, Spotify, etc. support screen casting. In fact, the Google Chrome app also has the ability to cast a tab directly to the TV.

All you need to do is find the Cast button on the app and choose your TV from the list.

Using Windows devices: Windows, by default, supports screen mirroring. However, you can use Google Chrome and Microsoft Edge web browsers to cast a tab. It can be a Netflix website or tab or a Google Meet call or anything else. Here are the steps you need to follow:

  • First, make sure you connect both the laptop and the TV to the same Wi-Fi network
  • Now open a new tab and go to something you want to stream on your TV
  • Now tap on three dots and choose Cast option
    • Microsoft Edge: tap three dots → More tools → Stream media to device
    • Google Chrome: tap three dots → Cast
  • Select your TV from the pop-up screen to stream the content.

Common issues with screen casting
Device not showing up
Make sure both devices are connected to the same Wi-Fi network. Also, make sure they support Chromecast or other streaming technologies

Stuttering or poor quality
Check to see if the two devices are no more than 15 feet apart. Also check your network speed once.
