I recently got rid of my 27in vertical monitor that I had been using for years. I found I was getting really stressed lately and feeling closed in at my desk. Getting rid of it has improved my mental health at work, no idea why it suddenly became an issue the last year as I used to have 3 when I was a twenty something.
I tried the big chonkers, but the humble 27" 1440p is unbeatable for me. I'm not being paid enough money to worry about that many pixels.
