From what I've seen, the tilting mounts do come out a bit further from the wall to accomidate the hinging hardware. This would allow you to fit your cables better, but at the expense of the slim factor.
I'm the one who started this thread, and I should mention that the peerless flat, non-tiltable universal mount I used actually included two sets of rails: thin and fat. I could have solved this whole issue by using the fatter rails - thier purpose is to space TV further from the wall.
But, like I said, I wanted tv as close to wall as I could; in my house, one can see the TV from the side when entering room.
I'm happy with my solution of making my own 90 degree cable by wiring in a home depot 90 degree plug to the stock samsung plug. And if you arn't as cheap as I am, there are links in preceeding msgs to AR and monster cables designed to be very snug to wall.
