Increasingly, people use two screens in their normal work. In some specialist work environments (e.g. control rooms), several screens may be used. Two or more screens are often useful when the person uses multiple software applications at the same time, helping to segregate work between screens and reduce the number of mouse operations. Multiple screens may also be used when people work together in groups.
Recommendations when using multiple screens:
- Minimise the gap between screens to ensure a seamless flow between them;
- Screens should be wrapped around the user in a semi-circle so that the distance between the user and screens is kept relatively constant;
- Unless there is a large number of screens they should be positioned horizontally around the person rather than stacked vertically;
- The distance of the screens from the person and the height of the screens should be the same as for one screen;
- Consider adjusting the font size of the text.
When working in groups, you should agree on the position and adjustment of the screens for the different people and agree on the uses and positions of the keyboard and mouse.
