diop My driver version is "361.43-desktop-win8-win7-winvista-64bit-international-whql". It works fine for me. I downloaded it a few months ago from nVidia. You can easily find a download link thru google. Try it. The cable I am currently using is dvi-to-dvi. Not sure if HDMI will make a difference.
I have not yet got a chance to retest the pre-anniversary windows 10 per Gurm's suggestion. Hopefully this weekend.
