Nowadays, due to the amount of data that we work with and the numerous applications available, the use of not only one monitor but two is required to be able to expand the content and visually have a much more centralized work. The problem is that when you connect a second monitor is not always detected by the system and that is why TechnoWikis has a series of solutions to correct this and be able to work with our two monitors without problems..
Although sometimes we do not have a second screen as such, we can solve it by putting a laptop as a second monitor and thus having two at the same time. In principle, the configuration between the two should be simple, but you may encounter a problem such as Windows not detecting the second monitor, so we will need to have options like today's to solve it.
