I wonder if this is a 14", 40 kHz monitor.

These lines are are incorrect.  They should read:

  "1024x768i"    45    1024 1064 1224 1264    768  777  785  817 Interlace
  "1152x900i"    45    1152 1184 1288 1360    900  898  929  939 Interlace

It's important not to get the "Interlace" on the next line.  If this
is your mailer's doing, consider that it could cause a lot of
problems.  There are alternative mailers--see
http://www.lemis.com/email.html.

Apart from that, they show a horizontal frequency of 35.6 kHz
(45000/1264) and 33 kHz (45000/1360) respectively.  I don't know of
any monitors which can't do that.

Well, for once it isn't :-) At any rate, there's very little
documentation available.  Ideally you need your monitor's
documentation--if you have that, you should definitely adhere to it.

Can you describe the "warping" more carefully?  This could describe
different problems.  I don't think it's liable to damage the monitor,
though.  [insert disclaimer here]

Well, I go into a lot of detail about this in "The Complete FreeBSD",
available from Walnut Creek.  It's more than I could reproduce here.

Shouldn't be too difficult.
