Thinkpad T42 and DVI output

Hi everybody,

I have a Thinkpad T42 and a 22" widescreen LG monitor (with both VGA and DVI inputs) and just added a "port replicator II" with DVI output.
The monitor resolution is 1680x1050 and I'm using Win XP.
I'm using the latest original IBM/Lenovo drivers for the ATI mobility radeon 7500 card inside my laptop.
I can drive the monitor with full resolution with the analog VGA connector but the image quality is quite bad.

I would like to use the DVI-D connection but the maximum resolution I can set for this port is only 1280x1024.

Is there anyone who can explain me how can I safely use the DVI-D output to drive my monitor at full 1680x1050 resolution?
Which drivers do I have to use and which is the correct installation procedure?

Thanks a lot,
Noel75
