I am currently using Windows 7 Sp1, Tkinter 8.5, Python 2.7.4 on a laptop with no attached monitor. I am attempting to use winfo_screenmmwidth, but the returned value is incorrect. Specs state 280 mm. Physical measurement is 275 mm. EDID states 280 mm. Tkinter's winfo_screenmmwidth returns 361 mm. I don't have very much tkinter experience, please bear with me.

So that's where I stopped on the X Windows side of things. I think I need to look at the source code for _tkinter.lib, but I'm not sure. I downloaded and started to look at the pywin32.exe (win32all) source code, but I'm not sure where to start with that either. I was expecting to see an entry which returns the EDID information, but I have not seen that yet. Could somebody point me in the right direction? Or does anyone have any ideas? Thank you in advance. -- https://mail.python.org/mailman/listinfo/python-list
