BenQ BDH01 Dual Monitor Arm 17"-35" 20kg Gas Spring Ergo Arm (Black)
PRODUCT DESCRIPTION
BenQ BDH01 Dual Monitor Arm 17"-35" 20kg Gas Spring Ergo Arm, Black (BDH01) - Local Warranty
Where the BDH01 Sits in BenQ's Five-Arm Ergo Range
The BDH01 is the heavy-duty dual arm: two independent gas-spring arms on one post, each rated 2-20 kg and each taking a 17" to 35" panel. Its stablemates are the single BSH01 (black) and BSH02 (white), which share the same gas spring and reach but take screens to 45". The lighter tier — BSL01 single and BDL01 dual — uses a mechanical spring, carries 2-11 kg and ships without a reinforcement plate. If both screens are 27" or larger, or either carries a webcam and light bar, the BDH01 is the dual arm to specify.
Two Screens at 20 kg Each on a Single Desk Mount
A dual arm is only useful if it can actually carry two real monitors. The BDH01 supports 2-20 kg per screen, so a pair of 32" 4K panels, or a 34" ultrawide alongside a 27", sits on one clamp point without the post leaning. Each arm extends up to 568 mm and moves independently, so a trader, designer or finance analyst can push one screen back and bring the other forward rather than being locked to a single plane. VESA 75 x 75 mm and 100 x 100 mm patterns are supported on both heads.
Gas Spring Tested to 25,000 Cycles, with Desk Protection Included
Dual arms load a desk edge harder than single arms, and that is where cheap mounts mark or deform a tabletop. The BDH01 ships with a steel reinforcement plate for thin, glass and other fragile tops, spreading the clamp load rather than concentrating it. The gas spring itself is fatigue-tested by BenQ to 25,000 cycles and paired with an optimised tilt structure, so neither screen sinks overnight or drifts out of the angle it was set to — the two complaints that stop staff adjusting a screen at all.
Clamp or Grommet, Top-Mounted, with Cable Management Built In
The BDH01 fits by C-clamp on the desk edge or through a grommet hole, and both tighten from above, so a two-screen rollout across a floor does not mean crawling under loaded workstations. Clamp fitting covers desks 17 to 50 mm thick without the reinforcement plate, or 12 to 45 mm with it. Cable management runs along both arms, which matters more on a dual setup where four to six cables would otherwise cross the desktop. Pre-installed components and a quick-release VESA head keep per-desk install time down.

Compatibility & Installation
Desk mounting
One mount point carries both arms, fitted either by C-clamp on the rear desk edge or through a grommet hole. Both methods are top-mounted. Without the reinforcement plate the clamp fits desks 17 to 50 mm thick; with the plate fitted it covers 12 to 45 mm. Allow for the 1075 mm overall width when planning bench desking.
What it holds
Two monitors from 17" to 35" each, with VESA 75 x 75 mm or 100 x 100 mm patterns, each weighing 2 kg to 20 kg. Webcams, light bars and soundbars bolted to a panel count towards that per-screen limit. For a screen larger than 35", use the single BSH01, which is rated to 45".
Movement
Each arm extends up to 568 mm, tilts 50° to -20°, swivels 90° either side and pivots 180° in each direction, so one screen can sit in portrait beside a landscape primary.
Cable management
Cable channels run along both arms, keeping video and power runs for two screens off the desktop.

Frequently Asked Questions — BenQ BDH01
How does the BDH01 differ from the BDL01?
Both are dual arms for 17" to 35" screens with the same VESA support and the same clamp-or-grommet fitting. The BDH01 uses a gas spring tested to 25,000 cycles, carries 2-20 kg per screen and includes a steel reinforcement plate. The BDL01 uses a mechanical spring tested to 20,000 cycles, carries 2-11 kg per screen and has no reinforcement plate, but tilts further at 68° to -45°.
Why does the dual arm stop at 35" when the single arm goes to 45"?
Two panels wider than 35" would collide and would overhang most desks. For a single large screen, specify the BSH01 instead.
Can I run two 32" 4K monitors on it?
Yes, provided each panel is 35" or smaller, weighs between 2 kg and 20 kg and uses a VESA 75 x 75 mm or 100 x 100 mm pattern.
Can one screen be portrait and the other landscape?
Yes. Each arm pivots 180° to -180° independently.
Can I mount it on a glass or thin desk?
The included steel reinforcement plate is intended for thin, glass and other fragile tabletops. With the plate fitted, the clamp covers desk thicknesses of 12 to 45 mm.
Does the arm have USB ports?
No. BenQ does not list an integrated USB hub on the BDH01. Cables are routed through the arms but the arm carries no data or power itself.
How much desk width does it need?
BenQ lists the arm dimensions as 1075 x 176 x 551 mm, so plan for roughly 1.08 m of clear width at full spread.
What warranty and invoice do I get?
Every unit sold by SourceIT carries a local Singapore warranty and is supplied with a GST invoice.
