Especially when giving presentations, there are times when having a second monitor is incredibly helpful. For the Work From Home lifestyle, it can be convenient to be able to use an iPad as a second monitor without having to buy the extra hardware while prices are so inflated. For students, maybe it's not easy to bring a second monitor while studying in the library: this is your fix. There is an issue of the older/budget iPads having pretty terrible battery life, so I caution that either you should have a splitter to both charge your iPad while being connected, or be really careful about how long you plan to use it/what resolution you set it at. I'm working between a Windows laptop and a iPad, so a solution like this is perfect, since most solutions are meant for the Apple ecosystem only.
