OK, following Andreas' comments I performed some search and found solution for windows. You can use WMI. WMI can be invoked from java using one of the interoperability tools (jinterop, jintegra, jawin) or by execution of external script (VBScript or JScript). The following script is an example:

 strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" _
    & strComputer & "\root\cimv2")
Set colSoftware = objWMIService.ExecQuery _
    ("Select * from Win32_DesktopMonitor")

For Each objSoftware in colSoftware
    Wscript.Echo "Caprion: " & objSoftware.Caption
    Wscript.Echo "Description: " & objSoftware.Description
    Wscript.Echo "PixelsPerXLogicalInch: " & objSoftware.PixelsPerXLogicalInch
    Wscript.Echo "ScreenWidth: " & objSoftware.ScreenWidth
Next

save it in file screen.vbs and run it using command line cscript screen.vbs Then ScreenWidth/PixelsPerXLogicalInch gives you width in inches.
