The most you would have to do with a low profile mount is get screws long enough to allow you to get past the bottom that sticks out. IF the wall mount screw is IN one of the portions that stick out than you just need to be concerened with spacing out top screw.
Be warned though a low profile mound makes it really difficult to hook up sources if they face the wall..same with working with the power cord.
I just bought this low profile mount for $14 from monoprice. Works great for my new Samsung UN55F8000. Probably 3/4" off the wall if that.
