At another help site, it was suggested to right click and "roll back" the driver. There is a driver showing and it indicated a problem (small yellow triangle next to the name of the driver). Go to control panel, device manager, display adapter.

Turned out that Windows 10 had indeed loaded.Īfter messing around with this for an hour and a half and reading lots of helpful tips from frustrated MS users, I did find a solution on my computer. I tried reloading Windows 10, thinking there must be a problem, but I had the whole white noise problem over again, turning off and on, completing two novels and a trip to the bathroom while I waited. However, the additional display could not be detected. It had white noise again, I turned it off and on again, and the second time the display came up on the primary computer. I ended up having to turn off the computer and restart it. ("Free" = "Beta version, you have been warned.") During loading Windows 10 my primary screen suddenly developed white noise everywhere instead of an image. I have a relatively new Lenovo PC with Windows 8.1. How I fixed the Windows 10 "second monitor cannot be detected" problem on my computer.
