VESA Standard

VESA Mounting Guide for Monitors

VESA© defines standards for mounting interfaces on monitors and TVs. The advantages of the VESA mount standard are many: It allows low-cost installation of displays into a broad range of applications while positioning screens for increased flexibility and ergonomic benefit. Use this guide to determine your monitor’s VESA compatibility and verify it will attach to a monitor mount product.

What Is the VESA Standard?

The VESA mount standard defines dimensions of the four-hole attachment interface on the back of displays and the screws used to fit those holes. It also dictates the placement of the hole pattern on the display. For attachment to VESA mounts, ideally the hole pattern should be centered on a display’s back. A center-positioned pattern minimizes torquing forces applied to the mount, allowing it to hold a heavier load.

Ergotron carries a comprehensive line of monitor mounts, which are engineered in accordance with VESA’s Flat Display Mounting Interface (FDMI) Mounting Interface Standard (MIS). When choosing a display, look for VESA compliance for ease of attachment to any Ergotron monitor wall mount, desk mount or computer cart.

Is Your Monitor VESA Compatible?

Use our Mount Finder to check if your display is VESA compliant. You’ll also find a selection of VESA mounts with which it is compatible.

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 MIS-D interface. Ergotron carries a comprehensive line of MIS-D-compatible VESA mounts.

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 monitors in this class weigh less than 50 lbs (23 kg). Ergotron carries MIS-E VESA 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 displays with large screen sizes often follow this variant. In practice, some 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 Ergotron VESA mounts for MIS-F displays are designed to handle more varied 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 from Apple, use a custom adapter bracket available from 3rd-party manufacturers. 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 VESA mount.
