Nowadays, a lot of people are working in offices, sitting at their desks and using computers. The number of screens used is increasing more and more. In the 90s, it was normal to have only one screen - now, it is very common to find people using two screens (or even more).
In some cases, using more than one screen is a real need. However, many times, the second screen is only used to display the mail inbox of the user, which is comfortable, but not a real need. Turning off that ‘useless’ screen could save a lot of energy.
The idea of this event is to encourage people who have more than one screen to use only one – as far as possible – during the month of June.
