System dpi

[Steve Long]

Hello,
can anyone tell me how to detect a system's settings for dpi settings on the
display properties dialog? For instance, it can be set to:
Normal (96 dpi)
Large size (120 dpi)
or
Custom size.

I'd like to do this on application start up and then just run with whatever
setting I find at that time. I've been looking and the System.Management
objects but have found the lacking so far.

Thanks in advance for your help.

Steve

Well never mind. I suppose I could just do:

Graphics g = this.CreateGraphics()
g.DpiX

should do it but I wasn't sure.

You can use EnumDisplaySettings API to retrieve the info
