Second monitor flickering on and off on Windows PC

If you have a two-monitor setup and the second monitor on your Windows 11/10 system is flickering on and off, this post offers helpful suggestions to resolve the issue.

Why is the second monitor flickering on and off on my computer?

In reality, the computer screen is constantly flickering, but we do not notice it. The Frame Rate for an entry-level monitor is usually 60 FPS, which means the frame changes 60 times per second. You need to make sure that both monitors have similar Frame Rates; otherwise, the flickering becomes noticeable, sometimes to the point where it is impossible to use them.

Other than that, faulty cables, misconfigured settings, corrupted, buggy, or missing drivers can cause the problem in question. The good news is that all software-related issues can be resolved without spending a penny; as for the hardware issues, you should contact the seller.
