Default [Q] Miracast Display works for a minute then disconnects

I have a Nexus 7 2013 with 4.4.4 on it. I also have a Freelander AP20 that works just fine with my Motorola Maxx 4.4.4 The Nexus works for about a minute and then the connection goes away. Any ideas as to why this is doing this and any way to fix it?

Thanks
