UI Scaling

It’s beyond frustrating that not only is this still a glaring issue, but that this isn’t a higher priority feature. I’ve now looked at countless threads, done tons of troubleshooting, and spoken with Adobe reps—the official recommendation just amounts to “change your monitor resolution” (!?). I’m on a 2021 Macbook Pro and use a Dell U2723QE as my primary screen, particularly for Illustrator, Indesign, and Photoshop. EVERY other app that I use on this external monitor, including Illustrator and Indesign, has proper UI scaling, meaning it’s not too large or too small (though Illustrator and Indesign are still too limited in scaling options). Meanwhile, Photoshop’s UI is comically small and the in-app scaling options feel like a joke in how little of an effect they actually have.

thanks d fosse for replying and for your explanation about illustrator vs photoshop. much appreciated!

And while I hear what you are saying - again thank you, adobe invests lots of time working on new features - but why develope new features if the environment you are providing to use them in (the UI scale) doesn't work for people on modern monitors on mac? This makes no sense...

and I know I'm not alone in using top of the line apple monitors for adobe's creative apps.

I don't do Mac and someone else will have to explain MacOS display scaling. As I understand, this is really a 5K panel natively, so 2560 x 1440 is scaled in the operating system.

But as for

How is it that Illustrator can scale properly, ditto Bridge but Photoshop is a nightmare

the explanation is that Photoshop needs to scale the UI and image window independently. That has a lot wider implications than most people think about. Vector applications like e.g. Illustrator and InDesign don't have this problem - they can just scale everything, UI, image, the whole thing, in one go. Photoshop can't do that. At 100%, one image pixel still needs to be represented by one physical screen pixel.
