Study: Two Monitors or One Ultrawide

Three people were selected for the study: the first person received a 24” monitor, the second participant – a 25” monitor with a 21: 9 aspect ratio, and the third participant – two 24” monitors. The study showed that the participants who performed tasks using two monitors spent less time compared to those who used a single monitor. It can be explained by the fact that opening the program for the task on one monitor and the task itself and the search engine on the other one, the employee spends less time switching between tabs, reviewing the task, etc.
