About VESA Standards

Ergotron mounts are compliant with the Mounting Interface Standard established by VESA©. Use our online tool to determine VESA Mount Compatibility to verify your monitor will attach to Ergotron products.

VESA Mount Interfaces

Ergotron products are engineered in accordance with the Flat Display Mounting Interface (FDMI) Standard, otherwise known as the Mounting Interface Standard (MIS), defined by VESA. When choosing a monitor, look for VESA Mounting Compliance for ease of attachment to any Ergotron wall mount, articulating monitor arm or other VESA-compliant mounting solution.

The VESA standard defines dimensions of a display’s four-hole attachment interface and the screws used to fit those holes. It also dictates the placement of the hole pattern on the back of the display. For attachment to VESA mounts, this invariably means the hole pattern should be centered on a display’s back (denoted in a VESA label with the letter “C” as in VESA FDMI MIS-D, 100, C).

Today’s flat panel displays commonly use three variants of the standard ...

VESA MIS-D monitor with Neo-Flex LCD ArmVESA MIS-D, 100/75, C compliant displays are equipped with either a 100 x 100 mm or 75 x 75 mm mounting hole pattern, using M4 screws. This is the most common interface for monitors weighing under 30 lbs (14 kg); small TVs and desktop computer monitors usually feature the VESA MIS-D interface.

VESA MIS-E, C compliant displays are equipped with a 200 x 100 mm mounting hole pattern, using M4 screws. Mid-size displays often use this interface; typical displays in this class weigh less than 50 lbs (23 kg).

VESA MIS-F, C compliant displays have varied hole patterns that are spaced in 200 mm increments (e.g., 400 x 200 mm or 600 x 400 mm), using M6 or M8 screws. Large displays with screens greater than 32" in size follow this variant. In practice, many displays in this class deviate from the standard in minor ways. For example, a 300 x 300 mm hole pattern is not uncommon. This is why most brackets for MIS-F-class displays are designed to handle irregular hole patterns.

Custom Interface Adapters

If your monitor does not include a VESA MIS-D, MIS-E or MIS-F hole-mount pattern, a separately-ordered custom adapter interface may be available. Contact the monitor manufacturer or Ergotron to see if this option is available. If an adapter is not available, the display cannot be attached to VESA-compliant mounting solutions.

Ergotron and the Establishment of the VESA Standard

In 1996, Ergotron-founder Harry Sweere traveled extensively to industry leaders around the world to lay the groundwork for the first mounting standard. Acting as the committee’s Group Leader, in 1997 the first VESA FPMPMI mounting interface standard was released. He went on to become the lead author of the revised and current VESA standard known as FDMI, which was introduced in 2002. A true visionary, Harry saw the need for a universal attachment interface on the back of flat-panel monitors and TVs, which would allow people to easily and affordably attach displays to ergonomic, articulating mounts.

Ergotron is a full member of the Video Electronics Standards Association (VESA), which is comprised of over 300 high-tech member companies who work on standards for the video electronics market that will shape the technology of tomorrow.
