Review on Enhance Your Display Flexibility with Mount-It! VESA Mount Adapter Plate - Expanding Compatibility for Monitors and TVs: Converts 75x75, 100x100, 200x200 to 400x200 mm Patterns - Includes Hardware, Durable Heavy-Gauge Steel Design by Jim Jarvis

I recently bought a new 55" TV and to my great surprise the mounting holes for the TV were on the BOTTOM half of the TV. The TV was approximately 6" tall. Also, the mounting kit I bought included a bracket that was not centered on the TV. For some reason the holes were a few inches away from the existing holes on the TV. Basically, I had a TV that was off-center and too high on my wall. I bought this mount as a last resort and it worked great! Not only did it center itself over the holes on the back of the TV, it even allowed me to lift it up a couple of inches to attach it to a crossbar I've previously installed behind drywall, it's very flimsy but very strong and the TV sits exactly where I wanted it. n is quite hard and so low you can't even tell it's there. I even had a bunch of gear that I ended up using. Do yourself a favor and if you're having trouble with the placement of the holes and/or brackets that come with most kits, try this and see if that solves your problem.
