Duet Display – This simple application can turn your iOS device into a real extra screen. Its function is simple, you connect the application on a smartphone and connect it to your PC, or Mac using a USB cable. The configuration of this application is almost unnecessary, and immediately after the connection you will be able to use not one but two screens! This is very convenient if you do not have a second monitor but you need more space for work or study.
