It’s important to note that not all monitor arms are created equal. Be sure to check the weight capacity range for your desired mounted monitor. A light monitor used with heavy duty arm will not provide enough tension to keep your it in the right position. Alternatively, a heavy monitor used with an arm designed for light use will be too weighted down. The size specifications and mounting bracket are essential too. Most monitors and monitor arms today are VESA mount compatible, but be sure to check the specs of both before you purchase.
