USDMonitor Mounts in Focus: Mechanics, Installation & Stability
This technical guide highlights the mechanical differences between various spring systems for desk mounts, analyzes the physical specifics of curved monitors, and defines the requirements for mounting a monitor arm to a desk.
The most important findings for choosing your monitor mount:
- Weight Priority: The decisive factor for the mount is the weight without stand, not the screen size (inches).
- Mechanics Choice: Gas springs for frequent position changes; mechanical springs for static, long-term positioning.
- Curved Factor: Due to the center of gravity shift, a weight buffer in load capacity is essential.
- Mounting Surface: For lightweight desks (honeycomb structure), the use of a reinforcement plate is technically mandatory.

1. The Mechanics: How does the mount move?
The heart of any dynamic monitor mount is the mechanism that counterbalances the weight of the screen. Here are the three common designs compared.
A. The Gas Spring
(Gas Spring Technology)
Function: Nitrogen gas in a cylinder creates counter-pressure. Offers the softest "floating" effect.
B. The Mechanical Spring
(Heavy-Duty Coil Spring)
Function: A steel coil spring is tensioned. Immune to temperature fluctuations and extremely robust.
C. Static Mount
(Fixed Pole Mounts)
Function: Fixed to a pole without counterweight. Maximum stability, ideal for touch applications on the desk.
2. Physical Fundamentals: Weight over Screen Size
From a technical perspective, the screen diagonal is of secondary importance for the static load capacity of a monitor mount. The decisive factor for compatibility is the actual weight of the panel (without stand). As long as the monitor weight is within the specified load range and the VESA standard matches, the screen size (in inches) is physically irrelevant.
Many buyers forget the minimum load. Springs have an initial tension. A "Heavy-Duty" monitor mount (range 2-15 kg) would permanently push an ultra-light 1.5 kg monitor upwards (rebound effect). Always check: Does your monitor weight lie between the minimum and maximum values?
3. Special Case: Curved Monitors
Strongly curved monitors (e.g., 1000R curvature) shift the center of gravity far into the room. This creates a strong leverage effect on the mount.
Comparison: Flat Screen vs. Curved
| Parameter | Flat Monitor | Curved Monitor |
|---|---|---|
| Center of Gravity | Close to VESA (approx. 2cm) | Far forward (up to 15cm) |
| Leverage Effect | Low / Neutral | High (Torque) |
| At 10 kg weight | Acts like 10 kg | Often acts like 13-14 kg |
The Consequence: A curved monitor stresses the tilt joint significantly more than a flat screen. Always plan for a weight buffer in load capacity when choosing a monitor mount for curved screens!
4. Desk Mounting: Clamp or Bolt-Through?
Solid fixation to the desk forms the basis for an ergonomic setup. The options shown below (Clamp & Through-Desk) represent the industry standard for monitor mounts. Complementary specialized solutions exist, such as wall mounts, slatwall systems, or freestanding stands.
Option A: The Desk Clamp
(C-Clamp)
The standard case. A clamp encloses the table edge and is tightened manually.
- Advantage: Non-destructive (no drilling), high flexibility.
- Disadvantage: Requires sufficient table overhang.
Option B: Through-Desk Mounting
(Grommet / Bolt-Through)
Fastening via threaded bolt through a hole or cable grommet, secured from below with a plate.
- Advantage: Maximum stability, visually integrated ("Clean Desk").
- Disadvantage: Requires a hole in the desk.
5. Desk Properties: Can the top handle it?
The leverage forces of a monitor mount acting on the desktop are significant. An analysis of the substrate material is essential:
Common in lightweight furniture (e.g. IKEA). The interior is hollow. Point loads lead to material breakage.
Solution: Mandatory use of reinforcement plates.
Optimal surface. The plate should have a thickness of at least 20mm to ensure sufficient stability for high leverage forces.
Not recommended. Glass tolerates point loads from a monitor mount poorly. We strongly advise against mounting on pure glass plates.

Conclusion
Prioritize the weight, consider the center of gravity shift for curved displays, and check the properties of your desk surface. These are the essential factors for safe installation of your monitor mount.
