It is quite rare to see a person performing only a single task at a time on a PC. Most of us have grown into proficient multitaskers and like working on multiple projects at a single time. Be it listening to music while getting your homework done or opening multiple browser tabs to write your report in Word. Creative personnel and professional gamers take the multitasking deed to a whole another level and have an unperceivable number of applications/windows open at any given time. For them, the usual multi-window setup doesn’t quite do the job and that’s why they have multiple monitors hooked to their computer.

If you aren’t able to check the box next to ‘Make this my main display’ or if it is greyed out, chances are, the monitor you are trying to set as your primary display is already your primary display.

Also, ensure that all your displays are extended. The ‘Extend these displays’ feature/option can be found under Multiple displays section inside Display Settings. The feature allows the user to set one of the monitors as the primary display; if the feature isn’t enabled, all your connected monitors will be treated the same. By extending the display, you can open different programs on each screen/monitor.

Other options included in the Multiple displays drop-down menu are – Duplicate these displays and Show only on…

As obvious, selecting the duplicate these displays option will display the same content on both or all the monitors you have connected. On the other hand, selecting Show only on … will show the content only on the corresponding screen.

Alternatively, you can press the keyboard combination Windows key + P to open the project side-menu. From the menu, you can select your preferred screen option, whether it is to duplicate the screens or extend them.
