Exactly same situation. Sorting out software side first but have a 40" tv I’m planning on using now and starting to think about the frame and mirror.
Got two samples of mirror today to test. One lets a lot of light and colour thru but isn’t very mirror’ie. The other doesn’t let colour thru but still looks Kewl. And looks good enough for normal mirror.
Frame I thought about metal. Had a google on making frames. Or buying a pre made aluminium tv frame which they make for displays etc.
Thinking now I’m either gonna use flat bits of wood. Or cornice gyprock type moulding to make straight picture frame. Then mount the tv to that.
So no glueing of glass/mirror.
It will go.
Picture/large painting frame
Mirror
Tv
Some sort of bracket to hold tv
Tv to wall mount
I could be way off and I’m sure there’s a heap of ways to do this but this is my latest plan (changes by the hour lol)
Love to hear what others are thinking.
Also check out the my build thread. It’s great to see what others have done.
