Hi Everyone,

I'm currently running Windows 7 on a late 2009 white unibody macbook. 2.26 C2D, Geforce 9400M, 2gb ram.

My Macbook is connected to a 23.5 in ASUS display via MDP->DVI. I normally run the macbook in clamshell mode, with just the ASUS display.

I just updated my 9400M drivers from the default Bootcamp drivers to the newest version (270.61) from Nvidia's website. After the update, my external display went black. With the new drivers I can only get the external display when running in extended (dual screen) mode. If I try to run in clamshell mode, there is no output to the external display.

Any ideas what could be going wrong? I reverted to the bootcamp drivers and everything is back to normal, but I would like to be able to take advantage of the update if possible.

Thanks.
