Thanks, Eli. I have the last four functions documented but not the first 
(variable?) in w32 24.3. I have put:

 '(display-mm-dimensions-alist (quote (("t400" 304 . 190))))

in (custom-set-variables using custom but that doesn't register the 
display monitor (14.1" diag.). Apparently the display part of the alist 
can be either nil, t, or a string but I can't get mm or pixel height or 
width through those functions after setting up the alist. Btw, what is 
this first string in the documentation of the variable:  (":0.0" . (287 
. 215))?
I was hoping that Emacs might be able to interrogate the hardware 
somehow through the OS.
In the context of my original question, is my goal somehow achievable. 
If so, what's the recipe? Hardware is Lenovo t400.


Thanks again,
