2 External monitors, both work but not simultaneously


Please help my aching head. :-/

I have two display adaptors and two identical, new iiyama monitors I want to use off an Acer Aspire 5735, Vista laptop. I know all the hardware is ok, it all works b…u…t not simultaneously ! Either or is ok, just not as I want.

My hunch is that each adaptor is looking for a separate driver but the software installation doesn’t seem to want to install the driver twice, saying it’s already installed and up to date. I’ve uninstalled the core software and still get nowhere.

I’ve tried switching off the laptop screen. Still, I can’t get the two iiyamas to show in the device listing as USB Displaylink. Always one defaults to Mobile Intel ® 4 series Express Chipset Family. Is there a work around?
