OK, so that's right out.  On reflection, I didn't think it would be
allowed.  24 is what you want.

Yow!  This is why your screen is black!  What made you think this tube
could do this?  An older one would have caught fire and burned down your
house.

Scroll up a few lines.  Your AMT monitor was made in December 1999.  The
screen is 32X24 cm.  The serial number is 4144.  There's a long list of
modes that it's capable of, but it ends with "1280x1024@75Hz" and
"1152x870@75Hz".  A little bit further down XFree86 tells you a list of
modes that it won't try because the tube just told it that it couldn't
do them.  That list includes "1920x1440".  But that (**) at the
beginning of the line says that you insisted that it should try
"1920x1440": 234.0 MHz, 90.0 kHz, 60.0 Hz.  Fortunately, your monitor is
smart enough just to go black, rather than blow smoke.

Wow, this i2c/ddc/Plug'n'Play stuff is fantastic, and XFree86 copies it
all into the log file for all to see.  Try setting up an old Workstation
monitor from 1992 that you have only the vaguest "probable" specs for.
