I want to get the physical size of the screen.e.g: UX50 is 480*320, Zire71 is 320*320. I find WinGetDisplayExtent or WinScreenGetAttribute cann't help me to solve it.
This is a situation where knowing what you're trying to do is crucial, since the answer will depend.
Why do you want to know? For example, if you want to know so you can size a dialog, then you don't want to know the physical size; you want to know the area in which app windows should appear.
The screen's density is also an important factor: do you actually care how many physical pixels are there? Most apps shouldn't care about that, which is why we have the concept of density to abstract that away.
Let us know what you're doing and why, then someone might be able to give you a helpful answer as opposed to a merely correct one.
