I just ordered the following dongle, and after plugging it in, my Vizio 50" smart tv says "NOT SUPPORT!". This is the dongle:
UG007B - 16G mini PC TV Dongle, Quad-Core RK3188 1.6GHz processor, 2GB RAM, 16GB Internal SD storage, Google Android 4.2, HDMI, 1080P, integrated WiFi
I can't accept that this won't work! Help!
