When the Google Chromecast came out over the summer, one of the first things many of us wanted to use it for was phone, laptop, and tablet screen mirroring. Basically, something like Miracast (or WiDi). Alas, I was under the impression that Google’s initial implementation only allowed for mirroring of tabs in the Google Chrome browser…on a computer, not a tablet or phone. Of course there’s the baked in support for Netflix, YouTube, Hulu Plus, Pandora and a handful of other apps beyond the Chrome tab mirroring, but I wasn’t aware of official full screen sharing.
As it turns out, Google includes an experimental feature that allows full screen mirroring — only on desktop operating systems, via a Chrome browser plugin, and currently without audio. We can assume this experimental feature will eventually become an official feature, and hopefully include full audio, better performance, and Android support.
We have been playing with the Chromecast ($35) screen mirroring and comparing it to Miracast, and it seems to work in a very similar way, though with some differences.
Google Chromecast Screen Mirroring
Miracast (or WiDi, Allcast, etc.)
All in all, both products work in similar ways, but each has its own benefits versus the other. Chromecast is the more economical choice, but Miracast has its benefits too, mainly maturity and features (at least at the moment) and built-in support with devices such as Smart TVs and projectors.
Sadly neither are compatible with each other, at least not at the moment. So you likely can use one or the other depending on your hardware—though it’s possible Windows 8.1 and Android 4.4+ will be able to support both at some point.
We’ll continue testing both options here at ZNF and will report back as we discover more!
