    Replicating your mobile screen

    Screen mirroring is a somewhat older technology that allows you to display the screen of your smartphone or tablet on your TV screen by producing a replica of your smartphone or tablet screen. You can use this function to view things on your mobile devices on a larger screen, for example, when showing pictures. Remember, you replicate the image and not the sound.  

    In recent years, screen mirroring became less popular because the technological standard took a different turn: casting content became more important than merely copying the screen. That's why modern televisions will often no longer have the screen mirroring option available. Alternative technologies on the rise are Google Cast, Chromecast or AirPlay.

    What's the difference between casting and mirroring?

    As mentioned before, mirroring creates a mirror image or replica of your smartphone or tablet screen on your television. It means that the content you play or view on your mobile device will be displayed simultaneously on your TV. However, screen mirroring does have some disadvantages: Apple devices don't support screen mirroring, and the protocol itself is no longer as reliable as modern variants. 

    Casting, on the other hand, is a more modern variant that works a bit differently. Casting content allows you to "throw" content to your TV. Your smartphone or computer tells the TV what to play, instead of playing it on your mobile device and mimicking it on the television. 

    In other words, your TV acts as the medium for your smartphone or computer instead of being a mirror.  A popular casting example is playing a YouTube video from your smartphone on your Sony's Android TV or displaying a website from your computer's Chrome browser. You open YouTube on your smartphone, select a video, press the casting button, and your TV does all the rest.
