Ergotron HX Desk Monitor Arm with HD Pivot White
PRODUCT DESCRIPTION
Ergotron HX Desk Monitor Arm with HD Pivot White (45-647-216) - 10 Years Local Warranty
Built for 1000R Curved Ultrawides up to 49 Inches
The Ergotron HX Desk Monitor Arm with HD Pivot (45-647-216) is the version of Ergotron's best-selling heavy-duty arm engineered specifically for deeply curved 1000R displays — panels such as the Samsung Odyssey G9 49″. A curved screen carries its mass further from the VESA plate than a flat one, and the heavy-duty tilt pivot is what keeps it locked in place instead of nodding forward over the course of a shift.
28 to 42 lbs of Rated Capacity, Held All Day
The arm is rated for 28–42 lbs (12.7–19.1 kg) with a monitor chassis depth of 6″–12″ (15–30 cm). That is a deliberately narrow, heavy band: this is a mount for one very large screen, not a general-purpose arm, and the specification is what makes it dependable on Singapore trading desks, simulation rigs, security control rooms and gaming suites.
Constant Force Lift and a Clean Desk
Ergotron's Constant Force™ technology gives 11.5″ (29.2 cm) of one-touch height adjustment even under a 19 kg load, with no gas struts and no tools. Removing a G9-class factory stand and floating the panel instead frees a substantial block of worksurface — and integrated cable routing keeps the power and DisplayPort leads off the desk.
Precise, Deliberate Motion for a Very Large Screen
The HD pivot delivers 20° of controlled tilt (15° backward, 5° forward), 180° of pan at the base and 360° of rotation at the arm joint. On a 49″ ultrawide these are the adjustments that actually get used: fine glare correction and swinging the whole screen aside, rather than the wide tilt sweep a small monitor needs.

Compatibility & Fit
This is the HX arm built specifically around 1000R curved ultrawides. A deeply curved panel puts its mass further from the VESA plate than a flat screen of the same size, which is why Ergotron fits a heavy-duty (HD) tilt pivot and publishes both a higher minimum weight and a monitor-depth range.
| VESA Pattern | MIS-D 75/100 — 100 x 100 mm and 75 x 75 mm |
| Screen Size | Up to 49″ diagonal |
| Screen Weight | 28–42 lbs (12.7–19.1 kg) — measured without the factory stand |
| Curvature | Engineered for 1000R panels, e.g. Samsung Odyssey G9 49″ |
| Monitor Depth | 6″–12″ (15–30 cm) without the stand |
| Number of Screens | One |
| Desk Clamp | Fits desk edges 0.4″–2.6″ (10–66 mm) thick |
| Grommet Mount | Fits holes 0.4″–2″ (10–51 mm) wide, up to 2.8″ (71 mm) deep |
Check the minimum, not just the maximum. The HD pivot is calibrated from 28 lbs (12.7 kg) upward. A lighter flat panel belongs on the standard HX Desk Monitor Arm (20–42 lbs) or, lighter still, on an LX Desk Mount Monitor Arm (7–25 lbs).
Tilt is deliberately narrower. The HD pivot gives 20° of total tilt (15° back / 5° forward) against the standard HX pivot's 75° range. That is the trade for holding a heavy curved panel securely — on a screen this large, small tilt corrections are all that is normally required.

Frequently Asked Questions — Ergotron HX Desk Monitor Arm with HD Pivot
What is the difference between the matte black and white versions?
Only the finish. 45-647-224 is matte black and 45-647-216 is white. Capacity, lift, tilt, VESA support and box contents are identical.
What monitor size and weight does the HD Pivot version support?
Displays up to 49″ weighing 28–42 lbs (12.7–19.1 kg) without the factory stand, with a chassis depth of 6″–12″ (15–30 cm). Both the minimum and the maximum matter — a lighter screen will not sit correctly on this pivot.
Why would I choose this over the standard HX Desk Monitor Arm?
Curvature. The standard HX Desk Monitor Arm (45-475) covers flat and gently curved screens from 20–42 lbs. This version fits a heavy-duty pivot engineered for deeply curved 1000R panels such as the Samsung Odyssey G9 49″, where the screen's mass sits further from the mounting plate.
Is this a single or dual monitor arm?
Single — and on a 49″ ultrawide that is usually the whole workstation. If you need two separate screens instead, see the HX Dual Monitor Desk Arm (45-476), which carries two displays up to 32″ each.
How does it mount, and how thick can my desk be?
A desk clamp and a grommet mount are both included. The clamp fits desk edges 0.4″–2.6″ (10–66 mm) thick; the grommet mount fits holes 0.4″–2″ (10–51 mm) wide and up to 2.8″ (71 mm) deep.
Do I need a VESA adapter?
Not for a standard 100 x 100 mm or 75 x 75 mm pattern — both are supported natively. Some large curved gaming panels ship with a proprietary bracket and require the display manufacturer's own VESA adapter plate; check the monitor's manual before ordering.
Can I retrofit the HD pivot to an HX arm I already own?
Ergotron sells heavy-duty pivots separately — SourceIT stocks the HX Heavy-Duty Tilt Pivot (98-540-216). For a new installation on a 1000R display, buying 45-647 complete is the simpler route.
Does it come with a Singapore warranty?
Yes. Every Ergotron HX Desk Monitor Arm with HD Pivot sold by SourceIT comes with local Singapore warranty and a GST invoice; Ergotron backs the HX Desk Monitor Arm with HD Pivot with a 10-year manufacturer warranty.
