Multitasking doesn't exist but distractions certainly do. This is one of the reasons I've stopped using multi-monitor setups.
My preferred set up is a large 4k monitor. If I can work with one application set to full screen, I'm happy. Normally though I end up with my editor taking up the left half to two thirds of the screen and the right section contains a browser or terminal.
I use virtual desktops and on my second screen I have my music player and all the messaging apps and email that I need. I flip to that desktop probably three times a day.
