Our Pick – Loctek D7L Monitor Mount

LOCTEK D7L MONITOR MOUNT
  • Arm easily adjusts to support an ergonomically correct workstation; sit more comfortably at your desk while reducing neck, eye and back strain, extend or retract monitor arm; rotate monitor to landscape or portrait mode
  • Choose the right mount: our D7L supports 13.2-33 lb monitors that are between 10”-34”; make sure your monitor’s VESA holes measure 100x100mm or 75x75mm
  • Aircraft-grade aluminum arm features a stylish anti-scratch surface.
  • Gas spring hovering system gracefully adjusts monitor height. Front-loading ports for audio, mic & USB 3.0

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.

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

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.
