It's all in the title :) Inserting a network card (or any other PCIe card, RAID controller, SAS, etc ) in the PCIe 16x slot of the Shuttle SG41J1 deactivate the DVI output. The VGA output still works fine.
Shuttle support says that it's a chipset limitation (G41 + ICH7), but that doesn't make sense to me : the VGA and DVI share the same hardware but the D/A converter stage.
Does anyone think that there may be some solution to this conundrum? Can a future BIOS update solve the problem?
