If you want to work ergonomically, choose a height-adjustable monitor for business use. You can move the screen up and down so employees of any height can look straight at the screen. This ensures a comfortable working posture and prevents neck and back pain. There are also monitors that you can tilt upwards or downward. That's less comfortable than a height-adjustable monitor. You also have monitors that can turn left and right or tilt 90 degrees. For the best sitting position, choose a monitor that is adjustable in any way.
