Device manager showing extra Generic Non-PnP Monitors

I'm certain the 2 responses by Mr_Moneybags and solomon219 are legitimate solutions for those situations and should be useful for those in similar contexts. That last post reminded me that I should post what eventually solved my problem.

The Dell Precision Workstation BIOS settings has a menu for Video with a submenu for Switchable Graphics. In that submenu is a checkbox for 'Enable Switchable Graphics'. Mine was checked on; I needed to check it off.

After that, the extra monitors immediately disappeared and have not returned and the Device Manager display was corrected as well.

I had the same problem :( Seems to be a bug in the latest Intel Driver. For me the solution was downgrading the driver one version so it still was officially supported by Windows 10, but also still had an Intel Driver installed.

I installed Intel® Graphics Driver 15.40.25.4463 for Windows® 10. (06/17/2016) from here. Intel Control Panel works perfectly, and the extra monitors are gone.

The full list of drivers is here

Intel® Graphics Driver 15.40.28.4501 for Windows® 10 (08/12/2016) did not work for me. The Intel Control Panel would not open (crashed right away) and I got 5 Generic-PNP monitors like you.

I have Windows 10 Version 1607.
