Default Mount sizes for HDTVs

How do TV makers decide which VESA mounting pattern to use for their TVs? I am looking at getting a 46 or 47" TV and the mounting patterns I have found include 200X200, 200X600, 400X400. Why not just use 200X200 (note that LG uses 200X200 on some 47" models and on others they use 400X400) since using a 200X200 gives the consumer far more mounting options? And don't tell me it is weight or size given the LG example of using 200X200 on some 47" TVs.

And why don't mount makers (like Monoprice) make mounts where the "size" rating matches the weight rating? For example when you look at many of their mounts that are for 23-40 inch TVs can generally hold 80 lbs. But in my research on 47" TVs these generally weigh around 40 lbs. They seem to assume that mounts that can handle mounting patterns like 400X400 or 600X200 need to handle 100+ lbs, but that is not the case - even TVs far larger weigh much less. So if you want to use a mount with an extendable arm on a 47", 40lb TV that uses larger than a 200X200 mounting pattern then you don't have that many choices for mounts and you need to mount across multiple studs.

Why not make a mount like the Monoprice 5921 (I would link to a photo but the link is ***ed out) that can handle larger mounting patterns and doesn't require mounting on multiple studs? Even most 60" TVs weight far less than the 80 lbs that this mount is rated for.

Is it because mounts haven't been adapter to the lighter weights that we see on TVs in the last few years.

my first guess would be that the size of the TV (xy, not weight) determines size of the mount...
So for a wider TV you want a wider footprint on the wall... something to do with leverage...

Imagine a 50inch mounted on a narrow mount... now put some weight on one extreme side of the TV (HDMI cable, clicking a button on the side)... because of leverage you could potentially "twist" the mount off the wall.

This is an uneducated guess at best...

I am resurrecting this thread as it didn't get much response. When I look at the mounts at Monoprice for TVs that are about 50-55" all of the mounts rated for this size TV can hold over 100 lbs. But not many TVs weigh that much these days.

Looking at a few TVs in the 50-55" range the weight is from 16-25kg -so the highest is 55 lbs. Therefore would there be an issue using a mount that is listed as being for a 24-37" TV that can support 80 lbs as long as it has the correct VESA mounting pattern (which is typically 400x400 for TVs of this size)?

I buy the argument above that the leverage will be more on a wider TV, but does that make that much of a difference? And a 50" TV with a thin bezel can be about the same width as a 42" TV with a very wide bezel.

I have read that you can use a smaller mount provided (as you noted) it meets the weight criteria and that it has the correct mounting pattern.

IMO, size is a bigger factor if you use a cantilever type mount where the TV can twist away from the wall. If you use a flat mount then it shouldn't be such a big issue.

My guess is that most wall mount problems occur when people don't attach the mount to the the wall studs properly!

I agree. TV mounts are not rocket science. However, I would err on the size of caution when it comes to weight. Too small a mount could also limit tilt and swivel. As XM4243 said, an important factor on keeping a TV from coming loose is the wall attachment. It's critical with a cantilever wall mount.

Thanks guys. If you read the specs for cantilever mounts that can take a VESA 400x400 pattern (which is the typical mount pattern for a 50-60" TV) you will see that, at least at Monoprice, they are rated at well over 100 lbs. This seems to be twice the weight of TVs of this size so you should be good. And almost all of the cantilevered mounts of this size are made to be lag bolted into two studs.

The mounts that are rated around around 80 lbs are usually mounted to one stud and they (usually) will only work with TVs up to a 200x200 mount pattern. So it looks like I may have to use the larger mounts unless I get an adapter plate that can adapt a 200x200 to a 400x400.

That's what I was thinking when I mentioned about the mounting pattern

I'd really avoid a kluge and I definitely would not put a 50 or 60" TV to a wall that was not bolted into two studs.
