Hi,

 

My house has a OMP M7416 tv wall mount. I checked its official website which mentions it supports up to 75kg and 50 inches.

 

My questions is that is it safe if I use it for a 65 inches TV?

 

I'm going to by a Sony KD-65X9500G which is far below the maximum weight but it is large then the maximum screen size.

 

Many thanks.

I would have thought the weight and mount hole locations are the really important pieces.  Where screen size could come into it a little is with the pivoting of weight (especially if the mount swings or tilts at all).

 

My guess, cause Ive never looked into it, is that the screen size affects the mount hole locations slightly.  Ive certainly seen mounts with differing holes for clearly different sized screens so it may come down to that.

 

So if you're prepared to accept the risk that the mount may fail.... I'd make up a template of the holes on the back of my TV and then go into the store and select a mount where the holes align just fine (and can hold the weight of the TV).

Should not have any problem as long as it has the same VESA type. e.g. 200X200

Thanks. The TV is VESA 300x300, I suppose it should be fine.

 

Update: Sorry for edit, I just want to add the quote. Sorry this is my first time reply. 😬

The Issue is this

 

"The wall where the display is attached must have a strength that can withstand 4 times (6 times in some models) the mass of the display."

 

https://www.sony.co.nz/electronics/support/televisions-projectors-lcd-tvs-android-/kd-65x9500g/articles/00228849

 

KD-65X9500G - Weight 23.5 kg

 

 

 

Your mount/bracket  is rated to 75kg,  so its only 3 times the weight, not the recommended 4 times...

 

The mount will physically fit the screen no problem, but its the weight ratio that's the issue.....

The bracket isn't the wall. Sony isn't law. Weight is weight.

Weight is weight, until its not, ... pulled cord,  hand grab by tripping person  etc....

 

Sony are simply saying they recommend a safety factor of 4, the mount has a factor of 3... of course it will hold up the TV...

At the risk of being shot down by a civil engineer a safety factor of 4 smells like the 1st guy said double it and his managers said "lets go with twice that just to be safe".

The mount doesn't have a factor of 3, the OP has a TV that is less than 1/3 the rated value of the bracket. The bracket will be capable of supporting something in excess of the rated load. Bratek brackets are tested at 3x their rated load, which would give a 9:1 strength ratio in this case, well in excess of the Sony recommendation for the wall.

 

Someone should tell Boeing the 1.54 strength ratio for the 777-200 wings simply isn't good enough. Bridges all around the world should also be pulled down as many fall below 2:1.

IME with a larger than rated TV, there are issues getting it onto the bracket since it is larger, it cant be tilted up enough to get onto the top rail before straighting up to get the bottom one on. Also the tv hits the wall when tilting it once you do get it on by mounting the TV way to one end of the arms that go on the back inorder to even get it onto the wall part.
