Some time ago in the distant past, the Video Electronics Standards Association, also known as VESA, thought it would be a sensible idea to put out a standard specification for monitor mounting. And so the Flat Display Mounting Interface (FDMI) was born. You might also see it referred to as the VESA Mounting Interface Standard (MIS) but most of us will just call it a VESA mount.
Just to confuse us, this refers to as a family of standards all designed to improve compatibility when mounting flat panel monitors, TVs, and other displays to stands and walls. So wehenever you are buying a monitor or mount, you need to not only look up whether it is VESA mount compatible but also what configurations are supported.
Typically, for PC monitors, most conform to the 100 x 100 fixture and you’ll probably see this mentioned frequently. Sometimes 75 x 75 too on smaller models. There’s no telling which VESA mount type will be used though, so do check when purchasing.
The VESA Mount standard
In most cases the attachment will consist of four screw-holes arranged in a square on the mount itself, with matching holes on the monitor. Fixing it in place is as simple as screwing in the four screws. It’s so simple, even I can do it! There is no quick release though so you’ll need to go through this process whenever you want to remove the mount.
The horizontal and vertical distance between the screws was originally 100mm, but as mentioned above a smaller 75 x 75 version also exists which you may come across when buying a screen. With the advent of bigger and bigger TVs there is now a version with 200 x 200 fixings and a screw pattern more appropriate for this size. You can see the full spec here.
Buying a compatible monitor and arm means that you can arrange your monitors as you please in your work space, if you have a multi screen setup it is particularly useful for ensuring they are lined up and your desk is decluttered. Monitor arms allow you to remove bulky stands that take up a lot of valuable working space.
