My screen space usage has always been pretty conservative — I have a PC and a Mac on my desk, and each gets a single 27" 4K display scaled to 1920x1080 at 2x. That's all I've ever needed for the kind of development I do.

(I settled there after years of damaging my eyesight at high res, and my eyesight has improved ever since)

Since I've started using Codex day to day, however, I kinda feel like I could be doing a lot more things at once if only I had a wider screen for more Terminal windows…
