How to get monitor size?

[Polaris]

Hi Experts:

Using C#, is there a way to get the display monitor's size in inches (for
example, I'd like to know if the monitor size is 15", 17" or whatever)?

Thanks in Advance
Polaris

No guaranteed way to get inches, even what Paul has suggested, as it is not
a required component of the interface between the monitor and Windows. You
can, as Paul has stated, get resolution.

Thanks. I tried that also, but the DpiX/DpiY didi not change when I change
the monitor resolution. Looks like they represent native resolutions only.

DPI (dots per inch) isn't the same thing as PPI (pixels per inch). The only way to get the true PPI of the current display is to divide the current resolution (width/height) by the monitors width and height in inches. Outside GetDeviceCaps, I don't believe there is a straightforward way to get the phisycal dimensions of the display.

DPI refers to ink droplet density in a priner matrix.

You may obtain the physical dimensions of the display using the EDID information stored in the registry. You can obtain the appropriate monitor's registry key using the EnumDisplayDevices windows API call.
