Using two monitors while working on your computer is very useful. The extra space allows us to be better organised and to see more things at all times. Unfortunately, not everyone can afford to buy a second monitor, or does not have enough space to keep it in a comfortable place. However, if we have an iPad or iPhone, we can make it work as a second monitor for our computer. If you have a Mac, chances are your iPad will be easy to connect thanks to the Sidecar feature. If your Mac doesn’t have this feature, or you’re using a PC, you will need to install a helpful app that allows your iPad and iPhone to act as a second monitor.
