Build Quality and Material
The most important thing to look out for when selecting a monitor stand is the build quality. The stand should have no flex whatsoever, and should be strong enough to support the monitor’s weight. Besides the flex, there should be no creaking sounds when you fit the monitor onto the stand. This is a sign that the stand is made of poor quality material, which would give way sooner or later.
Also important to note is the material that the stand is made from. Though most monitor arms are made of plastic or other non-magnetic materials, some manufacturers may also use electromagnets for electrical components such as a USB charging port. While you may think this is more “bang for your buck”, the circuitry’s magnetic field can interfere with the electrical components of the monitor, causing more harm than good.
If you are considering a monitor stand with power outlets, make sure the components generate low magnetism. This can be checked with a measuring device, or more conveniently with common household items such as a compass.
This is especially important if you use an LCD monitor, which has relatively narrow viewing angles. Make sure you get an adjustable height monitor stand, with which you can change the monitor’s altitude from the mounting point. It would also be preferable to get one with an adjustable horizontal swivel as well, though this isn’t as common. The manufacturer usually provides a swivel for adjustable height monitor stands, though more expensive monitor riser may also use electronic controls.
Next on the list are the mounting options of the stand. There should be a hole in the back of the stand in case of a wall mounting option, though more common are mounts at the bottom of the stand, which keep the monitor in place during use. The former is something you should consider if you plan on using your monitor as part of a home entertainment system.
