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.

We Don’t Like
Since the height is controlled by a gas spring, lighter monitors (below 25 pounds) aren’t heavy enough to fully lower the unit

Also Great – Ergotron LX Monitor Arm

Budget Pick – North Bayou Heavy Duty Monitor Arm

North Bayou Heavy Duty Monitor Arm
  • HEAVY DUTY COMPATIBLE: The monitor arm is suitable for mounting most HEAVY BIG screens 24"-42" in size and 4.4lbs to 33lbs (2-15KG) 
  • FULLY ADJUSTABLE: Tilt angles +12 to -12, swivel angles 90 and 360 rotation,
  • STURDY & STABLE CONSTRUCTION: Arm stand with both c-clamp mounting and grommet mounting are available.
  • ERGONOMIC: Improve your overall well being by creating most comfortable viewing angle for work or gaming- Enjoy the freedom to adjust your monitor height and angle: Your spine, neck and shoulder will be thankful

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.

The unsightly yellow North Bayou logo against the black metal finish. This is just a sticker however and can be peeled off.

Additional modifications may be needed to prevent the heaviest of monitors from tilting downwards

AVLT Dual Monitor Arm
  • Dual monitor desk mount fits most of flat/curved/ultrawide computer monitors up to 44lbs (20kg) each in weight with VESA 75x75mm / 100x100mm / 200x100mm / 200x200mm mounting holes.
  • SAVE VALUABLE SPACEHeavy-duty metal base only take up 6.5" x 4.3" (165mm x 110mm) desk surface. The c-clamp and grommet mounting options support up to 3.3" (85mm) desk thick.

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.

The USB 3.0 and the headphone/mic jacks at the base of the mount eliminates needs for extension cables and hubs

The cable management system is very neat and can only hold up to 3 wires
