With a monitor arm, you can attach one or more screens to your desk. This way, you ensure that you can easily rotate, tilt, and move the monitors. This isn't just convenient, but also ergonomic. Most mounts are made for a dual setup with 2 screens or a triple setup with 3 screens, but there are also monitor mounts for up to 6 monitors. Choose a monitor mount that you attach to the back of your desk, so that the screens don't take up space. Is this not possible? Choose a mount with a monitor base. Make sure to take a good look at the weight of your monitor and the maximum supported weight of the monitor arm, to avoid damage to your devices.
