We have CC 2017... but still not custom UI scaling

[andreamrg]

Today I've discovered the big news about CC2 2017 has gone out. Fantastic, I was so happy.
My happiness stopped when I've discovered Photoshop CC 2017 still hasn't a custom/intermediate scaling option for user interface.
Just 100% and 200%. And of course both aren't the best options to work with.
For example, my Spectre x360 is a 13,3 laptop with QHD display (2560x1440).

Setting PS to 100% gives me microscopic interface, and while I like tinty interface which shows a lot of information on the display, this is way too small and not the best condition in a working envinroment.

Selecting the 200% scaling leads to a enormous interface, wasting a lot of space and looking so clunky.

Sorry for the question, but does really Adobe can't provide a such basic and easy function to its software? We are at 2017 iteration of the software and we can't manage the UI scaling correctly.

I'm pretty disappointed.

100% scaling

200% scaling

Before you wrote your display was 3200 by 1600 now its 3200x1800??? If it is 3200x1800 toy should be able to scale it 225%  a 1422x800 UI display.   Photoshop support scaling up to 400% but you need the pixels requited for that amount of scaling 4096x3072px scaled 400% is 1024x768UI pixels.  Its a physical requirement.  Resolution is a pixels size thing the higher resolution smaller the pixels are, A 65" 4k HDTV  has a low resolution display its pixels are large. A 5" 1K 1920x1080 hdtv  would be a high resolution display and you would need to be very close to it to see the image and if is was Photoshop UI you would not be able to use it.  Its a physical size thing I do not think even you would think one could use Photoshop on a iPhone size display.

If you  set your 3200x1800 display scaling to 250% your display would be like a 1280x720px UI display 48px short of the 768 pixels required. If your display was a 3200x1920 display  scaled 250% it would be a 1280x768 UI display.

With CC 2017 you can set Photoshop's UI scaling to 100% and force Windows scaling onto CC 2017 and scale to 250% Your display will still be short 48 pixels but Photoshop will not complain. However, both Photoshop's UI and Image display will be scale 250% not just Photoshop's UI. Whane Phtoshop scala you images to 100% soom Windows will scale the to 250% you will never see toy images actual pixels except in your prints.
