This article sums up my own experience with every Miracast device I've tried until now. I dislike apple devices for many reasons, but I must recognize that airplay, Apple TV etc have been around for years and work perfectly ... if you accept to be stuck in a closed world. But at least if saves you from all frustrations you'll see in the what we believe is the open world ;-)
I've never seen a miracast device that works in a reliable way and with a user guide and GUI that looks a bit professional. It's truly junk !
The only thing that's more promising is a Chromecast key: it's easy to setup, reliable and looks great but ...
- nothing for Windows phones
- can't/won't play many codecs (AC3 audio / DTS / ... files have to be transcoded or recoded to play on this thing, which makes the interaction with DSVideo (synology) rather complicated).
- Synology for example will let you throw video or audio at it, but no photos.
- In windows you are limited to clone a chrome tab on the screen, but it's no true screen mirroring.
... Still waiting that someone comes up with a truly universal (and efficient) system before I change my TV to some smart TV that will be able to make good use of media servers and mobile devices. There are some models out there, but I wanted to keep this outside the TV, just use it as a monitor as those features evolve at a rate much faster than the rate at which we buy TV's (and I don't believe that any TV manufacturer will push firmware updates to stay up to date ... they normally want you to buy a new one every now and then eventhough you don't need it!).
