Using a monitor arm is important: an optimal monitor position is more comfortable and increases productivity compared to the wrong position.
By using two monitors you work even more efficiently and effectively. You are faster, make fewer mistakes, and are on top of things.
The high-quality Space-Arm Beam Dual has a support beam on the back where the monitors are attached, so the monitors are always at an equal height.
An ergonomically correct monitor position leads to reduced discomfort and complaints to the neck (Kumar 1994 McKinnon 1994, Marcus2002). The optimum position increases productivity by 10% (Sommerich et al, 1998). A relatively large viewing distance is less straining to the eyes, an arms length is recommended. A condition of this is that the characters on screen must be large enough to read easily (Owens and Wolf Kelly 1987). Larger characters can be read quicker than small ones (Tullis et al, 1995), small characters therefore decrease productivity (Jaschinski-Kruza, 1988).
