What Is VESA Mount?

VESA is a global standard for mounting, defined by the VESA Association. Most screens and TVs come with four screw holes arranged in a square at the center of the back panel. This standardised pattern allows monitor arms to securely attach to different screen brands.

Complete VESA Size Chart

VESA patterns for monitors include: 50 x 50mm, 75 x 75mm, 100 x 100mm, and 200 x 200mm, depending on monitor size and launch date. The most commonly used VESA sizes are 100 x 100mm and 75 x 75mm.

How to Check Your Monitor's VESA Compatibility
Finding your monitor's VESA size is simple:
  • Check product specifications on the manufacturer's website
  • Look for VESA information in your monitor's manual
  • Measure manually - use a ruler to measure the distance between screw holes.

Here are exceptions to watch out for:

A. Large and Small Screens: Larger screens may require a 200 x 200mm VESA mount, while some older or smaller screens use a 50 x 50mm VESA pattern. For 200 x 200mm setups, you’ll likely need an additional adapter plate.

B. Recessed VESA Mounts: Some 75 x 75mm VESA mounts are deeply recessed into the monitor’s back panel, which may cause compatibility issues with certain monitor arms.


C. Apple iMac & Studio Display: Only the VESA-compatible version can be mounted. Models with built-in stands cannot be converted, making it essential to verify VESA compatibility before purchasing.



D. Gaming Monitors: High-performance gaming monitors like the Samsung G9, Acer Predator, and ASUS ROG often feature unique VESA mounting designs. These typically require custom adapter plates for proper monitor arm installation, which might need to be purchased separately. Ensure the adapter plate fits both the screen and your monitor arm for a stable installation.

Final Considerations

Now you know how to check VESA compatibility and what to watch out for. Before buying a monitor arm, also verify your screen's size and weight specifications.
