200 × 200 and large VESA patterns (big, heavy displays)
Once you get past ~40 inches, monitors start using 200 × 100 or 200 × 200 mm VESA — a bigger, stronger bolt pattern for a heavier panel. Fewer desk arms support it, and load becomes the real limit.
Which arms support it
Standard gas-spring desk arms usually top out at 100 × 100. For 200-series patterns you need a heavy-duty arm or a wall/pole mount that explicitly lists 200 × 100 or 200 × 200 — and one rated for the weight, which is the harder constraint. Heavy & curved mounting →
Mixed patterns
Some large displays (e.g. Dell's 49" ultrawide) offer both 100 × 100 and 200 × 100. That widens your arm options — but a heavy panel still needs a heavy-rated arm regardless of the holes.

FAQ
Can I use a 100x100 arm on a 200x200 monitor?
Only with a VESA adapter plate that converts 100x100 to 200x200 AND an arm rated for the monitor's weight. On heavy displays that's usually a no — get a mount that natively supports the pattern and load.
Is 200x200 always heavier-duty?
It's used on heavier displays, but the pattern itself isn't the rating. Always check the arm's rated load against your panel weight.
