Multiple Montior-Need Help

[Guest]

Hi,
I'm new to the group and am looking for some help. I have an IBM ThinkPad
Pentium III running Windows XP Pro. I am trying to set up my display so I
can plug a monitor (Mitsubishi Diamond Pro 900u) into the back of the laptop
so I can drag my windows from the laptop to the monitor. When I plug in the
Monitor I get the same display on both.
I've gone into the settings tab and tried to switch the diplay to multiple
monitors and look for the expand my desktop options but I don't get the drop
down option for the mulitpl display where I can designate my primary and
secondary monitor.
When I plugged in the monitor it did not prompt me for new hardware but I
assume it's working since I can see the display on the laptop and the monitor.
When I look at the display tab in setting it says muliple monitor parethesis
but I don'tget the drop down or option to set up the multiple monitor.
Can some please help?

The driver AND adapter has to support Multiple monitors. Contact IBM to
see if your system has this capability.

Thank you Bob. I will check both of those at the IBM website and see if
there are any updates.
