Hi DaveM121,
I have this same issue on at least 7 devices ranging from brand new Dell Vostro 15 3000 laptops with the latest bios and drivers to HP Laptops using the Intel HD 520 and an even older Toshiba again using an intel driver.
They have all stopped working after the latest set of Windows updates and now either crash or simply do not recognise that an additional display has been connected.
Any help greatly appreciated
Alan
