hi,so i used to stream from my laptop to my panasonic viera and now have a new tv as thats going in my games room,i now have a panasonic tx-65hx580bz and same settings are there so streamed fine first 2 days now the tv dont pick up my laptop???
considering a miracast wireless device but wanted to fix this first,its annoying as comes and goes,it would be less annoying if it was constistly not working
