Yes, but it is not clear that 32x32 is actually correct, since the EDID 
does not match the actual size.

Run:

$ xdpyinfo | grep dimensions

I get this response on this monitor:

   dimensions:    1920x1200 pixels (524x331 millimeters)

To be absolutely sure what you are getting, you should put:

  Option "UseEDID" "FALSE"
  Option "DPI" "75 x 75"

into the Screen or Device section of xorg.conf. Making an informed 
guess, I think you need about 40x40.

That file is installed by the NVIDIA-Linux-x86(_64).20.19.36.run binary 
installer which is available at
http://www.nvnews.net/vbulletin/showthread.php?t=122606

run that file with the -x switch and it will extract everything (like a 
zip file), including the README.txt. Odd that the repository install 
does not include that file.

Well, I can only suggest that you increase the font size....or start 
trolling your local computer stores for a used flatscreen. 24" units 
with 1240x1024 resolution are available around here for pocket change, 
while higher resolution monitors are neither hard to find nor expensive.
