Miacast problem on Dell XPS 9343

I have exhausted all means to connect my Dell XPS 9343 via miracast to my LG UF770 tv. Everytime I connect or project it to my TV it will just time out and will give me a message "We didnt get any response from the device please try connecting again". and the tv monitor will just be saying connecting.  I have the latest windows 10 anniversary edition, updated all the driver. I also tried switching off my firewall, updating my TV software and tried it in at least 3 other TV's but still not connecting.  My network adapter  Intel ac 7265. The sole purpose of me buying this is to project  all my presentation to a tv. Anyone from the xps user having the same issues?
