The mounts we design and manufacture are made to fit the display fixing holes in the rear of the screen. These standard fixing configurations vary in screw size and distance apart between holes depending on size of display.

This fixing hole standard is part of a set of standards created by the Video Electronics Standards Association (VESA) based in California, USA. It all started in 1988 when NEC Home Electronics started the association to develop and promote a super VGA computer display standard as a successor to IBM’s proprietary Video Graphics Array (VGA). Many standards have been written but the one we utilise is the Flat Display Mounting Interface (FDMI), also known as VESA Mounting Interface Standard (MIS) or colloquially as VESA mount.

The first fixing hole arrays, measured in mm, were 50 x 50, 75 x 75 & 100 x 100 for 12” to 20” computer monitors. As flat screens began to take over the professional display market from CRT displays the fixing arrays became larger with a variety of sizes. The present-day variant to cover common large format displays is MIS-F with a range from 200 x 200 to 1000 x 1000 ascending in 100mm increments and using M6 or M8 fixing screws. Whilst the configuration is expressed as a square, many compliant screen manufacturers use a non-square pattern such as 600 x 400 and 900 x 600.

So how do you know what your screens fixing pattern is? It will either tell you in the screens user manual or you can measure the width (1) and height (2) of the fixing holes on the rear of your screen (see picture below). Most mount manufacturers make universal mounts, which are designed to cover the VESA range and these mounts are categorised by screen size and VESA fixing array they are most suited for. We mention the minimum and maximum VESA size each of our products is suited for on the website and within the catalogue - but if you're still stuck and want to double check, please call 01865 767676 where our experts will be able to provide a helping hand!
