The choice of a monitor arm defines your desk's aesthetic, ergonomics, and future upgrade potential. Today, we put two industry-leading single arms head-to-head: the sleek, integrated Secretlab MAGNUS Monitor Arm and the powerhouse, feature-rich Humanex TX03 "Shadow Hunter" Arm.
If you're looking to free up desk space and achieve the perfect viewing angle, this deep dive is for you. We’re breaking down the comparison across the three most crucial factors: Raw Strength, Price & Value, and Unique Features.
💪 Battle 1: Raw Strength & Capacity
For any high-performance setup, the first question must be: Can it hold my monitor? This is where the Humanex TX03 delivers a knockout blow.
Max Weight Capacity: The TX03 Power Advantage
| Monitor Arm | Flat Screen Max Weight | Curved Screen Max Weight |
| Humanex TX03 | 16.0 kg (35.3 lbs) | 13.0 kg (28.7 lbs) |
| Secretlab MAGNUS | 8.0 kg (17.6 lbs) | 8.0 kg (17.6 lbs) |
The Humanex TX03 handles twice the weight of the Secretlab MAGNUS. This massive capacity difference is critical if you own or plan to purchase:
-
Large Ultrawide Monitors (34-inch to 45-inch).
-
Heavy Professional Displays or 4K/OLED screens.
The TX03 ensures your investment is stable and sag-free, even with the heaviest displays on the market.
Max Screen Size & Desk Compatibility
The TX03 continues its lead in compatibility, supporting monitors up to a colossal 45 inches, flat or curved. The Secretlab arm limits you to a 34-inch display.
Additionally, the Humanex TX03 provides flexibility for various desks, supporting both C-Clamp and Grommet mounts, and accommodates thicker desktops (up to 75mm).
💰 Battle 2: The Price and Value Factor
When evaluating a purchase, true value means getting more features and performance for less money.
The price comparison reveals a clear winner in the value category:
| Monitor Arm | UK Price (Approx.) | Value Proposition |
| Secretlab MAGNUS | £139 | Premium design, optimal for Secretlab desks. |
| Humanex TX03 | £79.99 | Nearly 50% cheaper, double the weight capacity. |
The Humanex TX03 offers vastly superior capacity and monitor size support while costing significantly less than the MAGNUS arm. This makes the TX03 the undisputed champion for users seeking high-performance value.
✨ Battle 3: Features & Aesthetics (RGB vs. Minimalism)
The biggest difference between these two arms is their design philosophy.
The Aesthetics: Stand Out or Blend In
-
Secretlab MAGNUS: This arm is sleek, full aluminum, and highly functional, built specifically to seamlessly integrate with Secretlab MAGNUS desks (including a top-mounted clamp and perfect fit with the cable management tray). It’s designed to be elegant and almost invisible.
-
Humanex TX03 (Shadow Hunter): The TX03 is a statement piece. It features an angular, dynamic, and aggressively modern design. Its purpose is to elevate your gaming environment and stand out.
The X-Factor: Dynamic RGB Lighting
The Humanex TX03 is one of the few monitor arms on the market to feature integrated, dynamic lighting. The Multi-Layer Mirror Tunnel Lighting offers 20 different RGB modes, allowing you to sync your monitor arm's aesthetic with your PC, keyboard, and mouse lighting for a fully immersive, cyberpunk atmosphere.
If your setup is about pure performance and personality, the TX03’s RGB is the key differentiator.
Adjustment Flexibility
While the MAGNUS has a slightly longer reach and vertical range, both arms offer excellent articulation for ergonomic positioning. The TX03 boasts a comprehensive 5-axis adjustment system, including:
-
Tilt Angle: $+60^{\circ}$ to $-60^{\circ}$
-
Swivel Angle: $+90^{\circ}$ to $-90^{\circ}$
-
Panel Rotation: $+180^{\circ}$ to $-180^{\circ}$ (full 360-degree rotation)
🏆 Final Verdict: Humanex TX03 is the Uncontested Value King
The Secretlab MAGNUS arm is a superb, premium accessory—if you own a Secretlab MAGNUS desk and prioritize total desktop integration above all else.
For the vast majority of users, especially gamers, power users, and anyone with a large or heavy monitor, the choice is clear:
The Humanex TX03 dominates the key metrics that matter most:
| TX03 Advantage | Impact for You |
| 2X Capacity (up to 16kg) | Future-proofs your desk for the heaviest displays. |
| 45-inch Support | Handles the biggest ultrawides on the market. |
| Unbeatable Value (Nearly 50% less) | Delivers premium performance without the premium price tag. |
| Integrated RGB | Adds unparalleled style and personality to your battle station. |
