I was unclear.  It is not a driver issue, it is a kernel/OS issue,
that kept NEC from peddling these screens.  I'm not sure of the
details, but WinXP itself would not pass the information from the
apps to the drivers so they could render such high pixel screens.

Remember, this was not too long after the bad old days of DOS and
the early Windoze, when applications needed to drive the graphics
cards directly.  That is how Mentor Graphics got started, as a
graphics display company which had to write the applications that
could use its displays. 

If such limits appeared with X, we would find the offending code
in the server code, fix it, and send a patch.  Then return to
writing our driver modules.  Similar limits slowed the adoption
of Bluetooth, whose first implementations were in Linux.  A lot
of cancelled projects because of that.

Back to Citrix, there may be some control knobs to twiddle that
control window size, so I can bound the screen area that it uses,
perhaps even do magnification.  More experimentation needed.
