How to divide a monitor into 2 virtual monitors so that you can conveniently work with 2 documents at once

Answer 1

There are monitors (LG) with native support for such garbage. As for everyone else - google special software.
In general, to work with two documents, you can open 2 documents and "pin" one to the left side, and the second to the right - the benefit of win10 allows this (and win7 seems to be too)
