[?] dpi resolution

Hallo,
I want to know the dpi resolution of the pc (control panel - screen): I see I can set large characters (120 dpi), small characters (96 dpi) or customize it.
How can I know what's the actual dpi resolution?

I tried with api enumdisplaysettings but I have not what I want.
Any idea?

It's as easy as this:

dpi = 1440/Screen.TwipsPerPixelX

That will give you dots per logical inch, but the problem is that the operating system does not know how many inches across your monitor is so you cannot do better than that for dots per physical inch I'm afraid.

Yes, for a printer, or other output device, a logical inch is exactly equal to the physical inch, but for the monitor, we should be contented with the logical inch. Because now, the physical inch depends upon the dimensions of the monitor, the resolution, and even on the width of the screen that you set with the knobs on the monitor.
