When I try to upgrade from Windows 7 Home Premium to Windows 10 I keep getting a message that Windows 10 will not run on this PC because "The display is not compatible with Windows 10..." I have upgraded the monitor driver (9GR6N) with same result. I have a dual monitor set up with a HP monitor (HP w2338P) as the secondary monitor. Disconnecting this 2nd monitor does not help.
I previously posted this problem on the Dell Monitor forum and was assured that the monitor and driver were not the issue.
Any suggestions?
