Custom UI scaling

[MaxReece]

I recently bought a high res monitor and was bummed when I tried Photoshop. The UI is way too tiny. I have tried going into settings and changing the font scaling setting but that barely changes anything. I really wish there was a way to customize the scale of every aspect you display.

What version of macOS and Photoshop are you using?

Have you tried the macOS scaling options under Apple>System Settings (Preferences)>Displays?

There should be a Optimize for which gives the recommended settings for an external display.

Also look at the Resolution settings.

I realized my own mistake about 15 minutes age. I  was using native resolution when I should have been using HiDPI. thank you for the response,  I have no clue what I'm doing. 🙂
