After upgrading to Windows 10, I immediately noticed that my 3 display setup no longer worked. It was powered by two NVidia graphics cards (GeForce GT 640, and a GeForce GTX 550 Ti).

For some time, I couldn’t find anything on the internet explaining as to why I lost my dual display setup. Finally I came across a forum that pointed to this NVidia Support KB article: http://nvidia.custhelp.com/app/answers/detail/a_id/3707/~/windows-10-will-not-load-the-nvidia-display-driver-for-my-older-graphics-card

Essentially Fermi based GPUs utilize WDDM 1.3 mode, whereas the newer architectures of Maxwell and Kepler support WDDM 2.0. In Windows 10, it is not able to load multiple display drivers using different WDDM versions.

For a really long time I waited and no updates enabled the functionality until September when I performed an update, and out of nowhere they started to work. I assumed they fixed the issue permanently, however after updating once again, I lost the capabilities. In this case I reverted to the last driver.

I’m not sure if they updated the Fermi driver to support WDDM 2.0, but I just know it started working. And then after a short while, with another driver update stopped working again. Again, the driver rollback fixed the issue.

 

I recently upgraded to the latest build of Windows 10, and completely lost the ability once again, and lost the ability to rollback drivers.

It was time to find out exactly what driver version WORKS with both Kepler, Fermi, and Maxwell architectures.

After playing around, I found the WORKING NVidia driver version to be: 358.50

Load this version up, and you’ll be good to go! Hope it saves you some time!
