no DVI with VAIO in docking station



LS,

Brief description: monitor does not connect with docking station over DVI
while VGA works fine.
Configuration: Sony VAIO model VGN-BX297XP, with docking-station VGP-PRBX1
and Philips LCD monitor 200XW7.
Above configuration worked fine until some months ago the monitor broke down
and was replaced by a new one.
Next, the monitor did not connect at all (neither DVI nor VGA) and the
laptop was sent to a Sony repair station where motherboard
(graphics card), optical disk drive and harddisk were replaced.
After repair of the laptop, the docking station still did not give DVI
output; and finally the docking station was replaced by a brand
new one with no result.
So in effect, a new monitor and a (virtually) new laptop in a new docking
station have a major problem: no DVI output.
The drivers for the monitor were reinstalled; Windows indicates hardware
works fine, but it only does with VGA (both laptop direct and docking
station).
Updating the drivers for the graphics card (Radeon Mobile X700) results in a
Windows dialogue-box indicating that the latest revisions are installed.
Regarding troubleshooting I am really out of options; please advise.


Kind regards,
