XP multiple monitor support problem

trying to get multiple monitor support working under Windows XP Profesional.

video card is GeForce4 MX 440 (64 MB). card has 2 ports, VGA and DVI-I
main monitor is Dell M992.
nVidia driver is at 53.03, the latest.

M992 was originally attached to VGA port on video card and worked fine.
moved M992 to DVI-I port (using DVI-I to VGA adapter) and everything
still worked as expected.

hooked up an old NEC Multisync 3D monitor to the VGA port.

when i boot up i see the BIOS boot-up stuff on both monitors so i know the
signal is reaching the NEC. next the XP splash screen shows up on both
monitors. then the main display goes blank for a second (changing
resolution, refresh rate, etc.??) and then displays the desktop. however
the
NEC monitor never comes out of the blank state.

if i go into Display Properties -- Settings i only see the M992 listed.
there is
no drop down list presented.
Device Manager also shows only the Dell under Monitors.

i've tried setting the adapter to a 800 x 600, 16-bit, 60Hz state under the
premise
that maybe it was too high as a default state (before i could get in and
tweak the settings for
each monitor).

any suggestions?

the NEC is ancient (~1990) so it is not plug & play compatible. is this a
requirement
for multiple monitor support?



thanks!

Its a nVidia driver install problem, theyre not installed correctly.
Reinstall drivers, I had same probs eventually cured after reinstalling
several times.
Its also possible that if you updated drivers the card may still be
partially using old drivers, this also happened with mine.
