I have a 42" LG LCD TV that weighs 42 pounds and my single arm mount says it fits a TV up to 40" and 85 pounds. It has the standard 200*200 VESA connection with M6 screws and mounts just fine. Am I going to have a problem down the road because the TV is 2" bigger than they recommend? I've got 4 bolts going into a stud holding this thing on the wall and it's over 40lbs under the weight limit. Should I be concerned long term?

It's very solid on the wall and the arm works great. I needed something that would swing out and didn't want to pay $300 for a mount.

I'd be more concerned about the weight than the size, and it looks like you fall well under the weight max.

Yeah, that's what I figured especially since it's only 2" bigger than their recommended size.

yea I wouldn't taking a chance on this kind of thing. If it's over its weigh limit, there's a possibility the bracket could bent, or worse.

I think the size has more to do with the span of the mount so some TV's would be able to fit. The other thing is a smaller mount has the stress of the weight concentrated in a smaller area. But if you're solid in the studs and under the weight limit I'd say you were fine. If you were just in the drywall with molly bolts I'd worry.

It's an arm mount. Pretty much the same area on all of those. Unless you compare the absolute biggest with the absolute smallest.

If it fits, and it's under the weight, why not. Also, it's very close to the range of the mount, 42" on a 40" mount. No worries, I'd say. Go ahead and enjoy.

Agreed. Mine was for the 48" - 60" class so it's span was pretty big, I am in to 3 studs. As long as he is in to 2 studs securely the little difference in span won't matter.
