Before comparing both these technologies (Miracast dongle VS Intel Widi Dongle) to each other, we will take a brief look at them separately.
What is WiDi?
Wireless Display (WiDi) was technology developed by Intel that enabled users to stream music, movies, photos, videos and apps without wires from a compatible computer to a compatible HDTV or through the use of an adapter with other HDTVs or monitors.
What is Miracast?
Miracast is a streaming protocol that lets users mirror content from their Android mobile devices or Windows PCs to their TV screens. Unfortunately, Miracast-compatible receivers can be fickle. We’ve had the best results with the $70 Actiontec ScreenBeam Pro Wireless Display Receiver.
WiDi Vs Miracast
Difference Between Miracast and WiDi
The Miracast supports the latest Windows Operating Systems, Android 4.2+ OS, Mac OS, Linux Distributions, gaming consoles like Xbox One, etc. To use any of the medium, either Miracast or WiDi, you need a particular receiver device to use it.
The WiDi technology compresses and transmits the data through the channels by using the software and hardware functionalities of the device over a WiDi direct connection. While the Miracast is a standard made for the wireless connectors and receivers like smartphones, tablets, laptops, and TVs, monitors, projectors, etc. to mirror the screen of small devices on the bigger mediums.
So, what is better? After the Miracast introduction and the support the WiDi applications started to provide to the Miracast technology, the WiDi was discontinued for marketing and developing after 2015. It think, when comparing these two wireless platforms for copying your smaller screen content on the bigger displays, the Miracast is the best option to Screen Mirroring your Windows 10.
