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

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 TV wall mount, 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, ideally 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). A
center-positioned pattern minimizes the torquing force applied to the mount, allowing it to hold a heavier
load.
Check Your Display’s Compatibility
Use this tool to determine if your monitor or TV is VESA compliant. You’ll also find a
selection of mounts with which it is compatible.
Today’s flat panel displays commonly use three variants of the
standard …
VESA MIS-D, 100/75, C compliant displays are equipped with either a
100 x 100 mm or 75 x 75 mm square hole pattern, using M4 screws for
attachment of the mount to the display. This is the most common interface for monitors weighing under
30 lbs (14 kg); small TVs and computer monitors usually feature the VESA MIS-D interface.
Ergotron carries a comprehensive line of MIS-D-compatible products.

VESA MIS-E, C compliant displays are equipped with a 200 x 100 mm
rectangular hole pattern, using M4 screws for attachment of the mount to the display. Mid-size displays
sometimes use this interface; typical displays in this class weigh less than 50 lbs (23 kg).
Ergotron carries MIS-E mounts as well as an adapter kit that converts an MIS-D mounting plate to hold an
MIS-E display.

VESA MIS-F, C compliant displays have varied hole patterns that are spaced in
200 mm increments (e.g., 400 x 200 mm and 600 x 400 mm are both MIS-F
hole patterns). M6 or M8 screws are used to attach the mount to the display. Heavier TVs with screens
greater than 32" in size usually 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 Ergotron 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 custom adapter interface may be available. Contact the monitor manufacturer
or Ergotron to see if this option exists. If an adapter is not available, the display cannot be attached
to VESA-compliant mounting solutions.
Attaching Apple Displays to VESA Mounts
Most Apple displays are not VESA compliant. To attach a non-VESA-compliant Apple display to a VESA mount,
you may need an adapter bracket.
Apple
offers iMac computers with a built-in VESA interface. However, most iMac models from late-2012 to present
cannot be retrofitted to include a VESA interface—the built-in VESA interface is only available at the
time of purchase. If a VESA adapter is not available, choose a mount with a proprietary Apple interface or
use a custom adapter bracket. Update:
Apple’s iMac Pro is now offered with the option of a VESA interface accessory that can retrofit the
computer for attachment to a mounting solution.

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.
