Photoshop UI scale for Art.

[AlexWEM]

I set windows 11 Display scale to 250% for a large 4K cintiq display, but unlike most photographers or designers, I require the extreme opposite for the fastest art workflow possible, I require photoshop to open at 100% on any display, regardless of UI scale % set, the more space I have for the canvas to paint and texture the better for me, at the same time, I require to see as many brushes and layers I can possibly get, I'd settle for  - 200% (microscopic levels of UI sizes) but as it is, I cannot force photoshop to even open at 100% without setting the entire windows UI at 100%, I tried the usual - override high DPI scaling behaviour scaling performed by "application" and set photoshop UI settings to 100% UI font size to "small" nada, nothing! nothing worked, photoshop opens at 250%.

Is there anyone out there that got photoshop to launch at 100% even if windows is set at 150% or 250 and how?
I know is probably not do-able since everyone else keeps complaining that photoshop's UI is too small and they cannot see or read anything... kind of ruining the advantages of 4K displays, to display MORE not less... I hope adobe sets an option that is clear and works. still, Much thanks to everyone in advance.

Photoshop UI scaling follows the Windows scaling factor. That's hard wired and cannot be changed. The thinking is that what works for one application works for all.

This was in fact quite an engineering effort that took a long time, because unlike all other applications, the image window itself needs to stay un-scaled. That's not as easy as it sounds, and required some joint efforts with Microsoft.
