In this section you will learn how to get information about installed graphics conrollers and connected displays:

For function reference and examples we assume, that we imported systeminformation as follows:

const si = require('systeminformation');

Graphics Controllers, Displays

All functions in this section return a promise or can be called with a callback function (parameter cb in the function reference)
