Hi there,
So I'm upgrading my current pc to a cube case to put onto my desk. However, I would not have enough space to have my second monitor, so I am considering getting a vertical or square monitor.
My primary screen is 1920 by 1080p and 21.5" - I'm looking for a monitor that is similar in both width and I want to try keep the resolution as similar as possible so that I won't expect a massive window enlargement if I move one program to the secondary screen.
Could anyone suggest what I could get please?
