I have bought 4K 27-inch displays and I found that how disappointing is Photoshop with Camera Raw and Bridge.
As Photoshop can somehow adapt to Windows 10 interface scaling set to 150% without such option direct in app, Bridge and Camera Raw work only at 100 or 200% which is ridiculous. At 100% you cannot see anything, 200% is way too big.
And what's funny, despite Photoshop interface scale to 150% Photoshops cursors are 200% big which also looks ridiculous.
150% on 4K 27-inch displays is equal to native 2560x1440 resolution, which I found optimal for workspace on 27-inch screens.
It is very dissapointing that in year 2021 Adobe can't manage consistent interface scaling for high resolution screens.
