If you’ve been having trouble getting your third monitor to work on your Windows PC, here’s the solution to the problem.

We’ve all experienced those frustrating times when two monitors are connected to our computers, but the third one starts to flicker and disconnects from the computer. While this isn’t a major issue in most cases, it can be frustrating, especially when you are working on a project that requires multiple monitors. In this article, we will discuss how to fix this problem, as well as some other problems with your monitors.

On my Windows 10 PC, I have a third monitor which is connected to my laptop via a VGA cable. This monitor does not work. It keeps going to sleep, then wakes up, then goes to sleep again. On my Macbook Pro, I have a third monitor and similar issues. I have tried different VGA cables, and different monitors. I have tried different windows 10 settings, and different settings on my macbook. But nothing works.
