Our Pick – Loctek D7L Monitor Mount

This monitor mount will make your work area more efficient and more comfortable. It’s rated with the greatest carrying capacity of our test group and can hold monitors that are up to 34 pounds in weight and 34 inches in size – clearing your desk space, and holding your monitor at an angle that won’t cause you to strain your eyes, neck or back. 

With the D7L you have complete control over your monitor position to promote the ideal posture. The tension at each of the arm section can be customised so you can extend or retract the monitor arm, tilt it 90 degrees up and 15 degrees down, or adjust the height up to a maximum of 21 inches. You can even rotate your monitor to 90 degrees, letting you choose between landscape or portrait orientation. 

The Loctek D7L is made of aircraft-grade aluminum, which will resists scratches and looks very sleek and expensive. And thanks to its in-built cable management system, the typical tangle of wires is neatly organized and hidden away.

It comes with a clamp (for a desk edge) and grommet (for a hole through the desk), so you can install it straight out of the box. However Loctek reviews warn that the combined weight of the arm and monitor will require a desk thickness of at least 1 inch thick, or the monitor stand won’t be stable. Due to the stability needed to carry heavy monitors, it shouldn’t be installed on glass desks.

Also Great – Ergotron LX Monitor Arm

Able to carry monitors that weigh up to 25 pounds and are 34 inches wide it’s the sleek design which draws many to the Ergotron LX Monitor Arm.

Aside from ticking all the boxes you would hope for in terms of manoeuvrability, the LX has additional mounting pole options that allow you to raise the screen an additional 13 inches. A useful feature if you are working from a standing desk and wish your monitor to match your line of sight.

Wires and cables can be tucked inside to an in-built cable runner to maintain a clutter free appearance.

It’s rare to see a mounting arm in any color except black or industrial look polished aluminium. However  the Ergotron LX also comes in a classic white to suit all interior design styles, or even blend seamlessly against white walls to create the illusion of “floating screens.”

With a 10 year manufacturer’s warranty on all LX range products, the LX monitor arm is built to last, and having passed a 10,000 cycle motion test this confidence in quality appears to be justified.

Budget Pick – North Bayou Heavy Duty Monitor Arm

The North Bayou is a bargain gas strut assisted arm that can be used for screens up to 42” and a load capacity of up to 33lbs (15 kg).

Its heavy duty build quality mean that even when burdened with a heavy load, a wide range of customisations remain on the table. For example a 23″ range of motion along the horizontal axis allows you to pull and push your monitor out of the way if you use a very large or deep desk as your workspace.

The main point of concern raised about the NB by verified consumers is that the plastic on gloss metal connection points used to customize the angle of tilt or rotation of the monitor does not create enough friction to hold the heaviest of screens stable.

A cheap rubber washer picked up from the plumbing supplies section of any hardware store has been shown to solve this problem, and allows the components to hold fast without slippage. A small inconvenience for obtaining a monitor arm that offers huge cost savings vs units with similar capabilities.

Another thing that you should be aware of before buying is that the dimensions of the VESA plate (118mm x 118mm) mean that it might be too large to fit onto some monitors that have a sleek recessed VESA attachment point.

Worthy Mention – AVLT Dual Monitor Arm

If you are building a dual screen gaming set up, the AVLT is worth two minutes of your time.

Able to hold two monitors up to 35″ in size and weigh up to 33 lbs each, this monitor arm makes good use of a heavy-duty steel and aluminium construction.

Even if it’s loaded with as much as 66 pounds, the AVLT is particularly noted for it’s lack of wobble or sag thanks to sturdy gas springs which have been put through their paces in a 16,000-cycle motion test.

With adjustable gas struts you can configure monitors into a landscape and portrait orientation, and adjust their position and angle incredibly easily. And if you want to lock screens it in place, it has a special bolt design that with a few twists can hold steady even the largest and bulkiest monitors.

All cables are neatly stored using the detachable cable management system, and you have the option to mount it either with a solid double C-clamp or grommet mounts.
