Thanks Petey,
I made a cutout in the top (behind the TV) 

Thanks Oldtool,
Maybe a slide show?  Pictures show as much as I could tell.  I'm not a great talker.

Thanks majuvla, That's the brilliance,  if they ever go smaller I have job security,  they can pay me to make a frame to go around it.  (@82" wide I don't think they will ever go bigger)

Figuring out how to do something you have never done is what makes a good challenge.
