Default nexus 7 2013 and sony 42w650 getting sick and tired of gogle and their products

Ok so the magic nexus 7 witch is supossoed to be a tablet that works and do all kind of things basically can't do anything. Another big dissapointment is the display cast screen. Now, my tv a sony 42w650 works perfectly with my phone sony xperia z(yes i know it's a sony not a crappy asus) but still, the nexus 7 can do a screen mirror? It sees the tv but it wouldn't connect and then it reebots itself. i was a step away throwing it out of the window but i was afraid now the damage any cars parked in front of my house. I am very very dissapointed of this tablet and google.
