Why would my desktop suddenly stop recognizing my second monitor and how do I fix it?
When I start my computer, the BIOS message appears on one monitor in my dual monitor set up.
But when the computer login message appears on my windows operating system, it appears only
on the other monitor, and the desktop does not spread to both monitors.
Rebooting used to solve this problem last week, but now even that fails.
OS: Windows 10 (Build 18362.1316)
