The AV11 Single Monitor Arm will hold one monitor in a horizontal or vertical position. Having your monitors mounted on the arm will free up space on the desk, which can now be used for other valuable proposes. Low level monitors often cause neck and back problems because the monitor is below the required eye level for optimum body posture. The AV11 monitor arm allows the user to adjust the stand based on the height of the user to find the best height for each individual. Having the monitor at the correct height will reduce neck and back pain and have a positive impact on your productivity.
