ASUS ROG Ergo AAS01 Monitor Arm: features, specs and who it suits

The ASUS ROG Ergo Monitor Arm (AAS01) is a desk-mounted arm that holds a monitor off the desk surface and lets you move it. It is designed for people who want to free up desk space, tidy cables, or position a screen at a comfortable height and distance. ASUS says it supports a wide range of monitors, up to 39 inches.

What it supports

The listing gives these limits:

• Monitors up to 39 inches.
• Flat monitors weighing from 6.6 lb up to 23.35 lb (11.5 kg).
• Curved monitors up to 18.74 lb (8.5 kg).
• VESA 100 x 100 mm mounting.

VESA is the standard pattern of four screw holes on the back of most monitors. A 100 x 100 mm pattern means the holes form a square 100 mm on each side. The weight range matters: the lower figure is a minimum as well as a maximum, because a spring arm needs enough load to balance properly.

How the mechanical spring works

The arm uses a mechanical spring system, in which a spring offsets the weight of the monitor, so you can move the screen with light pressure and it stays where you leave it. ASUS says this gives smooth, effortless adjustment through height, tilt and swivel, and the description adds pivot, which rotates the screen between landscape and portrait. Portrait mode is popular for coding, reading long documents and web pages.

Spring arms usually have a tension setting, which you adjust to match your monitor's weight. Follow the manual for setting this and for securing the monitor to the arm.

Cable management and desk space

The listing title mentions cable management, which in a monitor arm usually means clips or channels along the arm that keep power and video cables tidy. Lifting the monitor off the desk also clears the area underneath for a keyboard, notebooks or a small desk lamp, giving a cleaner setup.

Setup and durability

ASUS describes installation as quick. It also says the design went through durability testing, including a 10,000-cycle range-of-motion test. That is the manufacturer's test figure. The listing gives the dimensions as about 6.1 x 22.8 x 25.8 inches, with a weight of 9.9 lb.

Who it suits

It suits desk users with a monitor in the supported size and weight range who want flexible positioning: gamers, remote workers, and people who switch between sitting and standing or between landscape and portrait.

What to check before you buy

• VESA pattern: confirm your monitor has 100 x 100 mm holes. If the monitor has none, it will need an adapter.
• Weight: check that your monitor falls between 6.6 and 23.35 lb (flat) or up to 18.74 lb (curved).
• Desk: find out whether your desk's thickness and surface can take the clamp or mount type; see the manual.
• Screen size and shape: ultrawide and curved screens have different weight limits.
• Reach: make sure the arm's height and extension suit your seating position.
