Windows 10 Dual Monitors Problem

[jeff1231]

Windows cannot detect second monitor for dual monitor application. Tried detecting dual monitors from Display Settings; however windows could not detect 2nd monitor. Tried installing original driver from HP website for ATI Radeon HD4200 graphics card, but ran into problem even after logging onto PC as administrator. Prevented from installing the driver by the PC. Could not roll back driver since no option was available. Also tried to install driver from ATI site, but was not able to restore dual monitor display. Both displays are the same. Unsure how to correct the display issue to restore dual monitor operation.

 This is a great location to get assistance! I read your post and see that your HP Pavilion p7 computer does not detect second monitor. I would like to help you resolve this issue. 

Let's start with the below steps: 

Update the BIOS: A BIOS update may be available and most known issues have been resolved with the latest F.13 update  

Check Monitors: All monitors don't have to be the same brand, type, or size, but all do need to support the same resolution.
