Because Duplica uses a web browser, you can mirror the iOs screen to almost any other device, both desktop (Mac, Windows or Linux) and mobile (iPad, iPhone or other devices), and it supports the sharing to a Chromecast and SmartTV also.
With Duplica you can mirror your iPhone and iPad screen on a web browser remotely without limitations around the world, all you need is just an internet connection.
The screen sharing via Chromecast is limited inside the same network.
The screen sharing currently is limited to 1 receiver device.
Some third party apps block the screen mirroring.
In this situation you will see a black screen on your TV.
Be it from the other end of the office or halfway around the world.
It is not possible to fix this issue.
