The Lengee WD01 is a newly released WiDi Wireless Display dongle for any TV or monitor with HDMI support. It’s $29 at GearBest and runs off USB power to power the device. It supports 1080p WiDI and Miracast standards. It also supports Wireless AC, so you can use the less crowded 5Ghz band.
So if you’re looking for a cheap Miracast or WiDi receiver, it might be worth a look.
