When I'm trying to use 3 monitors, 2 are active and the third monitor is forced inactive, I've already tried updating the graphics driver, reducing the resolution of the active display, using Win+P to set it to extend, and none of that worked.
When I try to configure the display extension directly from Start -> Settings -> System -> Display, I get the error “Failed to save display settings. Try a different combination of these settings."
I dual-boot with Linux that perfectly supports triple monitors with no problems, which leads me to believe it's a software lock in Windows, I want to know how to get around this software lock.
