Just saw your edit. I cannot, with clear conscience, take a credit for the uniqueness of the idea. The inspiration came from this, I just tailored it to my needs and specs. Not to mention the cost; these TV panels’ price range varies with size and runs anywhere from $550 to $1,500. So I threw together a Sketchup model (no dimensions):
Then did some extensive research on the materials. My FIL was a great help, the guy used to be a general contractor for over 40 years. Then we made a trip to HD and got to work.
Mine ended up costing just shy of $300 (building materials alone, mounting bracket not included).
