2707WFP and Latitude E6400

Hi All,

I recently got a new Latitude E6400 laptop with a new port replicator and the system does not recognize the 2707WFP monitor during boot up or once the OS loads.  I currently have to toggle the display us the FN + F8 keys once the system is booted and then change the resolution.  I have used this monitor previously with a Latitude D630 and its replicator for the past year and I never had an issue (monitor was great).  I have pinged Dell support but no luck, any thoughts?

Many Thanks,

Chris
