If I connect a monitor to my W541 mini DisplayPort, I'm able to use multiple monitors- everything works as expected, and the system is stable.
If I connect first a firewire device (I've a few- a Belkin Thunderbolt dock and a Promise Thunderbolt RAID array) and daisy chain the monitor on THAT, I get bluescreens (error often seen is VIDEO_DXGKRNL_FATAL_ERROR and no dump file).
The Lenovo supplied driver won't allow Factorio to start, so I've upgraded, but I can demonstrate blue-screens with modern software or the old drivers Lenovo supplies.
Is this a limitation of the Thunderbolt/mini DisplayPort on the W541? That I can only connect a monitor directly to the mini DisplayPort? I've tried Advanced options, reducing the RAM for the Intel card, but always, the NVIDIA drivers error (even when they're not supposed to be "used."). I run the same configuration on my P70 and have no issues related to video on that machine.

Still eventually crashes if I plug the DP adapter into the end of a device chain, regardless of driver (ancient Lenovo, modern NVidia).
Thanks anyway. Going to call support and see what they say (have weak hinges, too.).
