Another Dell that people mention is the Ultrasharp 2001FP. Apparently you
want one that was made before June 2005, because then it would be sure to
do 15kHz; some models going up to September 2005 apparently also had
support, but it's not guaranteed.

Do either the 2001 or 2007 support *digital* RGB/CGA out of the box?
