The Echo Show is a popular smart display with Alexa built in. You can use it for video calls, control smart home devices, stream music, and watch movies. But can you cast videos from your phone to an Echo Show?
The answer is yes, but only on certain models, and only from certain apps.
Unlike a Fire TV or Chromecast, not every Echo Show supports casting. In fact, none of them supported casting until recently. Amazon introduced this feature in 2024. It only works on Echo Show 15 and Echo Show 21, and you can only cast Prime Video from the Prime Video app.
If you’re wondering whether your Echo Show can receive casting or how to set it up, here’s everything you need to know.
What Is an Echo Show?
The Echo Show is Amazon’s line of smart displays with built-in Alexa. It combines voice control with a touchscreen, letting you watch videos, make video calls, control smart home devices, and check the weather. It comes in different sizes, from the compact Echo Show 5 to the larger Echo Show 21.
Unlike a regular tablet, the Echo Show is designed to be hands-free. You can ask Alexa to play music, show a security camera feed, or display step-by-step recipes. Some models have better speakers, larger screens, or built-in smart home hubs, but not all features are available on every model.

What Is Matter Casting?
Matter Casting is Amazon's solution to screen casting. The technology was introduced in 2024 as part of the Matter smart home standard. Echo Show devices do not support traditional screen casting, but some models do support Matter Casting.
Right now, only Echo Show 15 and Echo Show 21 support Matter Casting, AND it only works with the Prime Video app. If you try to cast from another app or a different Echo Show model, it won’t work. Amazon is expected to expand Matter Casting support to more devices in the future.
Unlike traditional screen mirroring, which duplicates everything on your phone’s screen, Matter Casting only sends specific content from an app to a compatible display.
