Check the Client's System Settings for Display Size

[Jared]

Is it possible to check the client's Windows system settings for desktop display size? My application requires the client's computer be set to Smaller (default) display size (96 DPI). I see how to check for installed RAM, screen resolution and color depth, but I don't see where to specify display size.

It is possible to check the current DPI setting. You can use this as a starting point:

local nDPI = Registry.GetValue(HKEY_CURRENT_USER, "Control Panel\\Desktop", "LogPixels");
if (nDPI == "") then
  nDPI = 96;
end
