... 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
Funny how you seem to believe that "checking stock prices" is a good use of a whole monitor but don't seem to see how literally any other task could benefit from having reference material up on a second monitor.
I think they mean anything where changes happen without your input, because you might see it in your corner of your eye, whereas reference material can be switched to almost as fast as you can look to the side. Typing as you're reading though...
Lol an actual unpopular opinion. I use 4 monitors. Sometimes I'm looking at reference documents on a second monitor to determine how to implement the function. Sometimes I have my dbms app up on the third screen so I can look at the data structure as I'm implementing it. And the 4th monitor is usually for YouTube so I have a background noise/video to keep me focused
As someone who has 4 screens at work and 3 at home, you've done a great job picking a truly unpopular opinion, as I had a gutteral negative reaction when I saw this.
Because lots of productivity tasks, including coding, involve looking at a reference material while creating the output. I'm frequently looking at a database structure on one window, an API document on another, and coding in an IDE.
You don't necessarily need two screens, but it helps to have enough real estate to view two or more applications at once. Personally I use a 50" 4k TV and tile things in halves or quarters - which is the equivalent of having four 1080 monitors.
I have two 40 in 4K monitors and a little 28 in 2K, my job involves network monitoring and diagnostics. No way could I work efficiently on just one screen unless it was ginormously bigly huge. I actually wouldnt mind another 4K but work machine hasnt the outputs
It kinda makes me disturbed to have something bright in the corner of my eye when I concentrate to read text. And even though I use tiling WM, most of the time I only have one window at once, rarely two windows split horizontally, but no more.
Imagine you have to cross examine 3 papers on your computer, you have to take notes and you have to input information on an excel document for your research paper thats on another word document. Try doing this on 1 screen.
I've always changed tabs, or at the very most, copy-pasted. I don't use split-screen though, as I find it too overwhelming and cramped for me. I've never found a reason to have 2 monitors.
If 1 is more than "enough", how many screens are enough then? Technically, if you never need any visual feedback from what you're doing with keyboard and mouse, then zero screens would be enough.
Once I went double monitor, I can't see myself falling back to a single monitor. I've used a single monitor for a good decade and a half before toying with double monitors. I just like being able to have things on one monitor and other things on another. It doesn't necessarily have to be a programmer-specific thing. I now reflect back and hated the idea of having to manage and check so many things while under one monitor. Things would be blinking, but oh wait, I'm gaming, oh wait, I'm browsing too and it's just too much.
