Monitor setup for home office. Window size problem.

Hello fellow devs. I hope I am not a schizophrenic and some of you had similar issue.

I have a 27 inch monitor + macbook laptop on the side setup.Also I am a fan of "Fullscreen" view of the app. I mainly use:

1. Browser
2. IDE
3. Terminal

The problem is that for 2k Resolution, fullscreen browser looks ugly, a lot of unused space, that drives me nuts. VS code too, feels too much stretched for no reason. (you have like your files on the left, and then…. some code in the left-mid part and then thats it.)

Basically my goal is to have all windows I work available for me at the same time. Thus thinking of ultrawide monitor maybe? But in this case. I will have to always look on either of the side of the monitor. This problem makes me crazy for some reason. Tried two monitors setup -> Neck hurts. And it doubles the problem with stretched windows in fullscreen.

P.S. 3rd year working from home, am I going nuts?
