E4300 DisplayPort not working

I have a Latitude e4300 with docking station, and I'm trying to drive an external monitor with the DisplayPort cable.  Windows won't detect the monitor.  Monitor keeps entering save mode.  If i switch to use a DVI cable from the docking station to the same monitor it works. 

Win 7x64 Enterprise, Mobile Intel 4 Series Express Chipset Family, Intel driver version 8.15.10.2413 (latest available from Intel). Monitor is Dell 2408WFP

Any thoughts?

Re: E4300 DisplayPort not working

Still not working, but two new bits of information:

1. When I boot the machine into safe mode, the display works through the displayport, and I can get it to work up to 1600x1200 (not the 1920x ) that the monitor supports.

2. Just tried a completely different computer, an e6400, with the same dock, cable, and monitor.  Same results.

Is there any way to reconfigure/update the monitor?
