A Miracast TV dongle allows you to mirror the display of your smartphone on your HDTV. To use this simply plug it into the USB port of your HDTV and you are all set to enjoy 1080p resolution rich content. Just make sure that your device is fully compatible with Miracast technology.
Miracast TV dongle instantly makes an HDTV smarter and intelligent as it lets you display movies, games, apps, and other content from your smartphone, tablet, or Windows 8.1 laptop on your HDTV screen. Since Miracast dongles are about the size of 3G dongles, they completely disappear behind the display and you do not have to play with wires.
Another thing to keep in mind is that you do not require an Internet connection to make everything work. Miracast technology is standalone and does not require a home network to work. Simply connect your Android phone or a Miracast compatible device to your HDTV and use it. For instance on Xperia smartphones, go to > Xperia Connectivity > Screen Mirroring > Turn on Scr.Mir. > Select Belkin Miracast.
