I have 2 identical ThinkPad W530 laptops model 2447-23G. Both are set to discrete graphics from BIOS because with optimus driver my projector will not work at all. I have other issue that causes blue screen when connect laptop to projector.
I have installed latest driver from Lenovo download site and yet still BSOD when connecting to projector. When I install driver from Nvidia site it fixes BSOD issue with discrete graphics and external projector.
Is there an issue with the Lenovo official drivers?

T430, T430i, T430s, T430, T530, T530i, W530
System is configured with:
NVIDIA Optimus graphics
Microsoft Windows 7
Please download and install the new Microsoft Windows 7 Optimus video drivers:
