I have a 40" 4K display, which I frequently switch between full 3840x2160 mode and 2560x1440 (HiDPI/Retina) depending on what I'm working on.
The problem is that with 3840 it's hard to read text, so in Finder I manually change text size to 14, and in Chrome I change Zoom to 125%.
Does anyone know a way to do this automatically when I switch resolution? Maybe there's an app?
I could write some scripts myself; I can change the resolution, but how do I change Chrome's "Page Zoom" from AppleScript or shell? And what about Finder? (I asked about this a while ago but never found a solution.)
