Ergotron LX Pro Dual Side-by-Side Arm Dark Grey
PRODUCT DESCRIPTION
Ergotron LX Pro Dual Side-by-Side Arm Dark Grey (45-686-293) - 10 Years Local Warranty
Side-by-Side Dual Monitor Arm with Independent Motion
The Ergotron LX Pro Dual Side-by-Side Arm in Dark Grey (45-686-293) holds two displays side by side, each on its own full-motion arm from a single desk clamp. Constant Force technology delivers smooth, consistent movement across the entire range of motion, letting each screen be extended, retracted, tilted, panned and rotated on its own. It is the natural fit for multitasking workflows — comparing documents, watching dashboards, coding against a reference — where two aligned screens do the work of one oversized panel.
13 Inches of Lift and 25 Inches of Reach per Arm
Each arm delivers 13" (33 cm) of lift, 85° of tilt (+70° / −15°), 180° of monitor pan, 360° of base-arm pan (180° with the rotation stop engaged) and extension up to 25" (64 cm). Bring both screens forward for close work, splay them for a wide field of view, or push them back to clear the desk for a meeting.
Two Displays up to 27 Inches on VESA 75/100
The LX Pro Dual Side-by-Side Arm carries displays up to 27" each, with a combined capacity of 8–44 lbs (3.6–20 kg) across both arms, on a VESA MIS-D, 100/75, C interface (100 x 100 mm and 75 x 75 mm). Verify both panels sit inside the published weight window, particularly with heavier 27" curved or high-brightness models.
Aluminium Build, Tidy Cabling and a 10-Year Warranty
Durable aluminium construction in a dark grey finish keeps two screens steady through years of daily adjustment, while integrated cable management with an added cable cover keeps the doubled-up cabling of a dual setup out of sight. Ergotron backs the LX Pro with a 10-year manufacturer warranty, supplied through SourceIT with local Singapore warranty support and a GST invoice.

Compatibility & Fit
The LX Pro Dual Side-by-Side Arm carries two displays up to 27" each, with a published weight capacity of 8–44 lbs (3.6–20 kg) across both arms. Weigh both panels (the figure is on the monitor's own spec sheet, not the box) and confirm the pair sits inside that window before ordering.
VESA: the arm's mounting plate is VESA MIS-D, 100/75, C — that is the 100 x 100 mm and 75 x 75 mm hole patterns, which covers the large majority of business monitors. Displays with a non-standard or recessed rear, and most all-in-one machines, need the monitor manufacturer's own VESA adapter plate.
Mounting: this listing ships with the two-piece desk clamp. Grommet and C-clamp bases are buildable options on this model rather than stocked variants — if your desk has a grommet hole or an awkward edge, tell our team the desk build and we will quote the correct base.
Ultrawide and curved displays: at 27" per display the dual builds suit standard and curved 27" panels; larger 34" ultrawides belong on the single-display LX Pro instead. Very wide panels also need clearance to pan without striking a wall, partition or the second screen.
Sit-stand desks: the arm mounts to the worksurface and travels with it, so it works on height-adjustable desks. The 13" (33 cm) of lift is on top of whatever range the desk itself provides.

Frequently Asked Questions — Ergotron LX Pro Dual Side-by-Side Arm
What is the difference between the Black, Dark Grey and White LX Pro Dual Side-by-Side Arm?
Finish only. All three variants share the same mechanical specification — same capacity, same lift, tilt, pan and extension, same VESA pattern and the same 10-year warranty. Choose the finish that matches your desk and monitor.
What size and weight of monitors does it take?
Displays up to 27" each, with a published capacity of 8–44 lbs (3.6–20 kg) across both arms. Weigh both panels against that range before ordering — two heavier 27" monitors can approach the top of it.
Can I mount two different monitors on it?
Yes, provided both have a VESA 100 x 100 mm or 75 x 75 mm pattern, both are within the size rating and the pair together sits inside the published weight range. Each arm adjusts independently, so mismatched screens can still be aligned at the same eye level.
Does it need a VESA adapter?
Not for a standard monitor. The arm mounts to VESA MIS-D, 100/75, C — the 100 x 100 mm and 75 x 75 mm hole patterns. Monitors with no VESA holes, a recessed rear or a proprietary stand need the display manufacturer's own adapter plate.
Can it be grommet-mounted instead of clamped to the desk edge?
This listing ships with the two-piece desk clamp. Grommet and C-clamp bases are buildable options on this model — send us the desk construction and we will quote the correct base.
Does it work with a sit-stand desk?
Yes. The arm clamps to the worksurface and rises and falls with it, and adds 13" (33 cm) of its own lift plus 85° of tilt on top of the desk's range — useful for fine-tuning screen height between seated and standing positions.
How does the Side-by-Side Arm compare with the Dual Direct and Dual Stacking builds?
All three carry two displays up to 27" with the same 8–44 lbs (3.6–20 kg) capacity and the same motion figures. Side-by-Side gives each screen its own full-length arm for the widest independent placement; the Dual Direct Arm uses a more compact linkage; and the Dual Stacking Arm places one display above the other for narrow desks.
Is the LX Pro Dual Side-by-Side Arm covered by warranty in Singapore?
Yes. Every Ergotron LX Pro Dual Side-by-Side Arm sold by SourceIT comes with local Singapore warranty and a GST invoice; Ergotron backs the LX Pro Dual Side-by-Side Arm with a 10-year manufacturer warranty.
