… if you know how to use virtual desktops and shortcuts. You can’t look at two screens at a time, anyways.
One use case I can understand is having a 2nd monitor for checking stock prices or checking for a certain event. Other than that, I don’t see how it contributes to “productivity” while working or coding for example.
P.S: Tiling WM users may understand this post more
I have 3 27" 4k screens in this layout: | - -. That’s from left to right, portrait landscape landscape.
I have a terminal and sometimes on the 1st screen. Code/Work on the second. Documentation/chats/email on the 3rd.
It works well for me :)
