Ergotron HX Desk Monitor Arm Matte Black
PRODUCT DESCRIPTION
Ergotron HX Desk Monitor Arm Matte Black (45-475-224) - 10 Years Local Warranty
Heavy-Duty Monitor Arm for Displays up to 42 lbs (19 kg)
The Ergotron HX Desk Monitor Arm (45-475-224) is built for the screens that overwhelm ordinary mounts: large 4K panels, professional colour-grade displays and ultrawides up to 49″, weighing 20–42 lbs (9–19 kg). Where a standard arm sags or creeps under that load, the HX holds position all day — which is why it is the arm specified for Singapore trading floors, broadcast suites, CAD stations and design studios.
Constant Force Lift — 11.5 Inches of One-Touch Height Adjustment
Ergotron's patented Constant Force™ technology balances the arm across its full 11.5″ (29.2 cm) of vertical travel, so even a 19 kg display glides to a new height with a fingertip and stays there. No gas struts to lose pressure over time, no tension knobs to release, no tools.
23.6 Inches of Reach That Gives the Desk Back
The arm extends up to 23.6″ (59.4 cm) to bring a large screen right to the user, then pushes back against the wall or partition when the desk is needed for paperwork. On the 600–700 mm deep bench desks common in Singapore offices, removing a heavy factory stand and floating the screen instead recovers a genuinely useful strip of worksurface.
Full Motion With a Clean, Cable-Managed Installation
70° of backward tilt and 5° forward tame overhead glare, 360° pan swings the screen to a colleague, and portrait rotation suits code, documents and long reports. Integrated cable routing along the arm and extension keeps power and video leads off the desk, and both a desk clamp and a grommet mount are supplied in the box.

Compatibility & Fit
The HX Desk Monitor Arm is Ergotron's heavy-duty single-screen desk mount. Its defining number is capacity: 20–42 lbs (9–19 kg), roughly double a standard LX arm, which is what makes it the right choice for large 4K panels and ultrawides that defeat lighter mounts.
| VESA Patterns Supported | MIS-D 100 x 100 mm and 75 x 75 mm; HX Single also supports 200 x 200 mm |
| Screen Size | Up to 49″ diagonal |
| Screen Weight | 20–42 lbs (9–19 kg) — measured without the factory stand |
| Minimum Screen Weight | 20 lbs (9 kg) — lighter panels will not hold position on this arm |
| Number of Screens | One |
| Desk Clamp | Included — two-piece clamp for the desk edge |
| Grommet Mount | Included — for a hole through the worksurface |
| Wall Mounting | Not applicable — see the HX Wall Monitor Arm (45-478) for wall installation |
Ultrawide and curved screens: the HX is designed for exactly this class of display. Flat and gently curved ultrawides up to 49″ and 42 lbs are handled by the standard pivot. For deeply curved 1000R panels such as the Samsung Odyssey G9, order the HX Desk Monitor Arm with HD Pivot (45-647) instead — its heavy-duty pivot is engineered for that curvature.
Important minimum-weight note: the Constant Force mechanism is calibrated for a 20–42 lbs load. A typical 24″ office monitor is too light for this arm and will drift upward; use the LX Desk Mount Monitor Arm (7–25 lbs) for lighter screens.

Frequently Asked Questions — Ergotron HX Desk Monitor Arm
What is the difference between the HX Desk Monitor Arm finishes?
Only the colour. 45-475-026 is polished aluminium, 45-475-216 is white and 45-475-224 is matte black. Capacity, lift, reach, VESA support and box contents are identical across all three.
What monitor size and weight does the HX Desk Monitor Arm support?
Displays up to 49″ weighing 20–42 lbs (9–19 kg), measured without the factory stand. Note the minimum as well as the maximum — screens lighter than 20 lbs (9 kg) are outside the arm's calibrated range.
Is this a single or dual monitor arm?
Single. For two screens use the HX Dual Monitor Desk Arm (45-476), which carries two displays up to 32″ each. Three-screen setups can add the HX Triple Monitor Bow Kit.
How does it mount to my desk?
Both a desk clamp and a grommet mount are supplied in the box, so the arm can either clamp to the desk edge or drop through a grommet hole in the worksurface. No separate purchase is needed.
Do I need a VESA adapter?
Usually not. The HX supports VESA MIS-D 100 x 100 mm and 75 x 75 mm, and the HX Single additionally supports 200 x 200 mm. Displays with a larger or proprietary pattern need the screen manufacturer's VESA adapter plate.
Will it work with a 49-inch curved ultrawide?
Up to 49″ and 42 lbs, yes. But if the panel is a deeply curved 1000R display such as the Samsung Odyssey G9, order the HX Desk Monitor Arm with HD Pivot (45-647) — Ergotron builds that version specifically for 1000R curvature.
How does the HX compare with the Ergotron LX Desk Mount Monitor Arm?
Capacity is the dividing line. The LX Desk Mount Monitor Arm (45-241-026) carries 7–25 lbs (3.2–11.3 kg) and suits typical 24–32″ office monitors. The HX carries 20–42 lbs (9–19 kg) up to 49″ and is the correct choice for large 4K panels, heavy ultrawides and professional colour-grade displays.
Does the HX Desk Monitor Arm come with a Singapore warranty?
Yes. Every Ergotron HX Desk Monitor Arm sold by SourceIT comes with local Singapore warranty and a GST invoice; Ergotron backs the HX Desk Monitor Arm with a 10-year manufacturer warranty.
