Windows not detecting second monitor
Your second monitor isn't plugged in fully, the cable is damaged, or Windows hasn't detected it yet. Check the cable connection first, then try unplugging and replugging it into a different port. Windows will find it right away.
When a second monitor won't show up, the connection is either loose, the cable is bad, or Windows needs a nudge to find it. We'll check the cable, try different ports, and update your display drivers if needed.
