I'm sorry, but I can't help you. The picture on the Web page was taken 
from an IBM press release. 

(I don't normally like to use pictures I didn't take myself, but I'm
pretty certain that using a photo that IBM provided in a press release
for the purpose of publishing articles about the product advertised in
the press release falls under "fair use". As a graphic designer, I'm
sensitive to copyright issues, but I believe that I'm in the clear
here.)

I've never actually attached a monitor to my Model 250. I recently ran 
across a client who had been using a Sun monitor with an adapter on
one of his home PCs. When I expressed interest in it, he said that
he'd sell me the monitor for $25, but the adapter cable cost him $75
so he wouldn't let that go. Fine with me! I just have to lug it across 
town one of these days.

So I may plug that monitor in as a novelty the next time I do an
upgrade that requires me to power down the system (which will be a sad
day--I'm rather proud of my 161 days of uptime), so I can see what
it looks like, but now I do everything on the machine (including writing
this email) by ssh or through s1.

Well, I have something here in the Common Diagnostics and Service
Guide about the GXT150, but be warned that this is the GXT150 MCA card 
and may differ from the one in the Model 250, which IIRC is not
exactly the same as the add-on card. It says that there are switches
on the card, and has a set of switch settings for different monitors,
which are almost all IBM models.

The last listing is "other displays." It lists "Screen resolution
(non-interlaced) as 1280 x 1024 at the following refresh frequencies
and display switch settings:

 freq | 1 2 3 4
---------------
60 Hz:| 0 1 1 1
74 Hz:| 0 1 1 0

(apologies for those using proportional fonts)

If it were me, I'd open up the case and see if there are dip switches
near that 13W3 video connector.
