I have a 2560x1440 monitor at home and 2x 4K monitors at work. I like my home setup better because the tools I spend most time with (vscode and Xcode) lock all their panels to one window making the real estate more important then the pixel density. I still have not found a way to get a 4K display not to display in “retina” 1080p without it getting too small, blurry or laggy.
