What’s the difference between Chromecast and Miracast?


When looking at Chromecast, I came across mentions of Miracast a few times, which I’d never heard of even though it has been around for a while. Like Chromecast, Miracast is a dongle that plugs into the HDMI port of a TV and acts much like a physical HDMI connection. So is Chromecast and Miracast the same thing, or is Chromecast a different version of Miracast? Are there any significant advantages of one over the other?

They are not the same, although they have similarities as you already pointed out. Essentially, just think of Miracast as an HDMI cable without the cable. What is on your tablet or other device will simply be displayed on your big screen. The device will function normally. Chromecast, on the other hand, is more of an independent device that allows you to control it through the Chrome browser, and operates more or less independently of the tablet/pc/smartphone.

Miracast was a certification program in May 2012 by the wi-fi alliance announced, this technology can realize various wireless video transmission between the device and make the equipment free from cables.


It is the latest technology, which make the wi-fi break through the wireless Internet. More specifically, Miracast is a mirror screen solution, through the wireless connection, we can project the small devices (e.g., smartphone, tablet, or computer) multimedia content and screen images to a large share of the display.


As wireless media sharing is becoming more and more popular, Miracast have to prepare for large-scale use. Consumers will be able to quickly and easily in a portable device's favorite video content or presentation to share to the Miracast certification televisions, projectors, and other consumer electronics products.

Chromecast vs Miracast – what’s the difference?

"With Google launching its new $35 Chromecast dongle, there’s a bit of confusion around how it compares with Android 4.2′s new Miracast feature and whether or not the two are the same thing.

So what’s the Chromecast vs Miracast story? Miracast is a new feature integrated into Android 4.2 that allows two supporting devices to create a direct ‘peer-to-peer’ connection between themselves over Wi-Fi for the purpose of audio-video mirroring. It’s a bit like Intel’s WiDi (wireless display) technology. In fact, WiDi supports Miracast as of version 3.5. The idea with Miracast is that it allows you to transmit up to 1080p (1920×1080-pixel) video and 5.1-channel digital audio over a direct-connect Wi-Fi link between say your supporting phone and a Miracast dongle on your big-screen TV. In that regard, Miracast is a bit like using a Bluetooth audio dongle where audio is played and transmitted from an Android smartphone via Bluetooth to a tiny Bluetooth dongle connected to your audio Hi-Fi setup."

The difference is level of dependency on your Android device. Miracast requires your Android device to be active while in use (via the Miracast dongle). Chromecast only needs your Android device during initial set-up, after which it will be able to play the content desired no matter what your device is doing.

It sounds as if Chromecast is preferable, with the exception of battery consumption.

Simply speaking Miracast is a one of the wireless transmission standards, which mainly focus on mirrioing video and audio from compatible devices such as Smartphones to TV. Now as a new feature Miracast is integrated into Android 4.2.


Chromecast is similar but works differently. It’s basically a single-function mini PC that streams video from  the web via its own Wi-Fi hotspot that must link into your existing Wi-Fi network. So rather than a direct connection like Miracast, Chromecast links into your Wi-Fi network.
