Thank you for joining the Intel communities.
Did this system worked fine before and then failed or this configuration never worked?
Are you using any adapters to connect your second monitor? If yes, try using straight connection.
Try updating your BIOS with your system manufacturer and see if there is an INF driver for you monitor that can help you; you can take a look to INF driver information here:
Please try installing our generic driver you can download it at the following link:
Ivan, thank you for your reply.
1) I'm not tying to project to a second screen, Windows thinks I want to and the 'Project' screen keeps popping-up.
2) The Lenovo G500 laptop I purchased had Windows 8 installed. The problem did not happen on Windows 8
3) I upgraded to Windows 8.1, the problem started under this release and now continues under Windows 10 which I upgraded to 8/15.
3) I have the current Bios offered by Lenovo for the laptop.
As I stated in my original post, the problem is erratic. I appear to be in a good period at date, but it could turn quickly and when it does, I cannot use the laptop much as the pop-up limits how much I can type and access email and websites.
I will download the generic driver and install it when the laptop fails again.
Thank you for clearing that up and let me know how it goes after you update the driver.
Also, I suggest updating your system through Windows update and all of the drivers from your system manufacturer website and it will be good idea to let know Lenovo about this issue as they are more familiar with your system and how the components interact with each other.
