I just upgraded from Windows 7 to Windows 10 Pro 64bit on a Opitplex 960. The video driver reports having a problem ( Intel HD Graphics 188.8.131.5259 ) because of this issue it does not allow me to detect the second monitor. Both monitors work during boot up and then when logging into windows... Once windows it fully booted I lose the 2nd monitor. I tried installing driver from DELL support page and also from the Intel Driver support page.. intel driver support page indicates that there is not a updated driver.
Any help with this would be awesome.
