The product is portability and works flawlessly with Windows 8.1.
Wirelessly display content in up to 1080p HD video resolution.
It also works with Intel WiDi pre-installed devices.
It supports Fast Booting and Loading, and DVD/CD/JPEG playback.
Easy to set up, hold remote and get great picture quality.
But it doesn’t have built-in storage and the menu system is poor.
I have update software version of the mainstage and intel widi, and everything works without issues.
Trying get full 1080p youtube videos from my tablet to TV’s big screen and it works really well.
The audio over HDMI cable is pleasant suprise.
