Option to change (Increase) the user interface size - toolbar, menubar, icons/tools, font etc. on Macbook - Tahoe Operating System, WITHOUT changing the screen resolution.

I am using a MacBook Pro 16-inch, Nov 2024 model, Apple M4 Max and currently on the updated Tahoe 26.4.1 MacOS. 

I like the resolution I have chosen for my inbuilt screen on my laptop, as I am doing design/photography work. I have my resolution set to 2624 x 1696. 

I gone into the Photoshop settings within the program, and into the Interface section, and changed the UI Font size to ‘Large’ and have ticked the box for ‘Scale UI To Font’. The ‘UI Scaling’ option with a dropdown box is greyed out for me and I cannot change this. 

I shouldn’t have to change the resolution on my device in order to view the text properly on Photoshop. That is currently the only solution I have been able to find for this issue. Which isn’t a viable solution for me. 

I have also gone into the Apple System Settings and used the display accessibility options to increase font size - which hasn’t helped with any of the Adobe software.
