Able to play videos, music, photos, documents, etc in my smartphone with any devices (smartphone, smartTV, laptop, tablet, etc) at anywhere internet is available. This application can only play contents but send screen as is such as HDMI, MHL, Miracast and Chromecast.

As it does not send screen as is, it does not need extra dongle or cable. All you need to do is to connect each device with same router.
