I’d say all is bad with MacOS and external monitors... It can’t manage text scaling like Windows, so you either have to downscale resolution and get everything blurry or keep the ridiculously high native resolution and have everything tiny :(
Is it not visible for you in the displays settings? You DO need all the monitors to have the same DPI or you’d have a window rendered half in one dpi and half in another when dragging across a display boundary.
No, when it’s an external screen I don’t get any scaling options, only the choice of resolution. I have a 24” QHD, so either it’s ridiculously small 2500xSomething or it’s blurry HD :(
I have this problem as well. I actually run my 27-inch 4K screens downscaled on MacOS because the tiny font at native-4K gives me a headache.
The worst thing about it is that scaling seems to use more CPU than running natively and the OS has some noticeably additional latency when running scaled.
Odd, my main setup is an external 4k monitor and I only use it with the “large text” text scaling and I have no complaints, the text is clear and large and easy to read. Perhaps you’re also using your laptop screen as well?
