How to choose a monitor arm
Choosing the best monitor arm starts with verifying three key specs from your monitor: its VESA mounting pattern (usually 75x75mm or 100x100mm), its screen size, and its weight. The arm you select must support all three. Next, consider your desk. Check its thickness and material; many arms are only recommended for solid wood desks and may not be suitable for glass, very thin, or hollow-core surfaces.
Adjustability is crucial for ergonomic comfort. Look for a good range of tilt, swivel, and height adjustment to position the screen at eye level. Finally, consider the mounting mechanism. Most offer a choice between a C-clamp (which attaches to the desk edge) and a grommet mount (which goes through a hole in the desk). Ensure the clamp fits your desk’s thickness.
What to look for
- Compatibility: Confirm the arm matches your monitor’s VESA pattern, size, and weight.
- Desk Fit: Check the mounting clamp’s thickness range and desk material recommendations.
- Adjustability: Look for sufficient tilt, swivel, and height range to achieve a comfortable viewing angle.
- Warranty: A longer warranty can indicate the manufacturer’s confidence in the product’s durability.
FAQ
What is VESA mounting?
VESA mounting refers to a standard pattern of four screw holes on the back of a monitor or TV. The most common patterns for monitors are 75x75mm and 100x100mm. You must check your monitor’s manual or the back of the monitor itself to confirm its VESA pattern before purchasing any monitor arm.
Can I use a monitor arm on a glass or standing desk?
You must check the manufacturer’s listing carefully. Many monitor arms specify that they are only recommended for use on wooden desks. Using a clamp on a glass desk can pose a risk of cracking. For standing desks, ensure the arm’s clamp can securely attach to the desk’s frame or edge as it moves.
What’s the difference between a gas spring and a mechanical spring arm?
Gas spring arms use pressurized gas in a cylinder to help counterbalance the monitor’s weight, allowing for smooth, float-like movement. Mechanical spring arms use a physical metal spring system. Some listings suggest mechanical springs may offer more consistent performance over a longer period without the potential for gas pressure loss.
How do I adjust the tension on a monitor arm?
Most monitor arms have a tension adjustment knob, usually located at the joint near the VESA plate or at the base. You turn this knob to increase or decrease the resistance, allowing the arm to hold your monitor’s specific weight steadily in place. Always follow the manufacturer’s instructions for adjustment.
