How to Fix Third External Monitor Keeps Disconnecting in Windows 10

Do you have an extra third monitor to extend your Windows 10 computer desktop screen display? When one is not enough, you add another to make two called a dual-display system. But, the Windows operating system supports multiple monitor setup. Sometimes, three is better to make things more productive and efficient. A third monitor comes in handy when you have several apps and websites to use simultaneously. It makes you see everything clearly and in one glance without having to close and open the apps and browser tabs that you need.

But, what if this additional screen monitor simply keeps on randomly disconnecting from your PC? Or worse, your third external monitor is not detected or recognized by Windows at all. If it does, it will prevent you from moving forward to your productivity goal. You can fix the issue with several of the solutions below.
