The size your image display on displays depends in the display being use DPI resolution. Display's do not play the Images resolution game. Image pixels are display using the Displays DPI not the Images DPI. Printers will paint the image using the correct size pixels. Image resolution DPI is pixels size. Changing the Pixel size changes the image size without changing a single pixel. Photoshop's Image size with resample not checked all that changes the resolution the pixel size.
Display are run at their native pixel resolution they are manufactured with a single fix size pixels size. Ink Jet printers do not have pixels. They paint in pixels on your paper using many smaller than pixel size droplets of ink to form larger printed pixel on the paper. Printers resolution settings is a wuality setting.
I think the is what Art-boards are for. I do not develop for the web. To me It looks like Adobe is addressing the problem at the device level not so much at the DPI resolution. You create version for different devices.
Thanks for answer but your reply seems to be complex and hard to understand for basic english speaker like i am and I just didnt understood the text in full range. So there is no possibility how to deal with it, right?
In simple English then you image will display at various sizes. The user Display resolution (DPI) is the the final factor.
(Number of Pixel in width Width)/Display DPI = Inches wide
(Number of Pixel in Height)/Display DPi = Inches high
change your settings in your OS driver to 1920x1080 so others will see the image at the same scale.
Well, 1920x1080 also 2048x1152 are blurry and i need work at pixcel perfect base :-/ for now i borrow a 24"
but what about some solutions in 2017, when there is still dumb problem with UI scaling. What about document scaling... must be way how to software recalculate ppi and show it in photoshop (only while work). ez
What you have to consider is that if you want pixel-perfect, you have only two options: Either one image pixel is represented by exactly one screen pixel - or one image pixel is represented by exactly four screen pixels. Your options are View > 100%, or View > 200%.
Anything in between will involve resampling / scaling and considerable softening.
That display size and resolution (2560 x 1440 at 25 inch) is really non-standard and awkward. You're falling into a 5% category in terms of on-screen reproduction size. "Everybody" else will have either higher or lower pixel density.
I suggest you experiment with viewing distance, trying both 100% and 200%.
