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 60FPS, which means, the frame is changing 60 times a second. You need to make sure that both the monitors have similar Frame Rates, otherwise, the flickering becomes perceivable, sometimes, to an extent where it is impossible to use it. Other than that, faulty cables, misconfigured settings, corrupted, buggy, or missing drivers can cause the problem in question. The good news is, all the software-related issues can be resolved without spending a penny – as for the hardware issues, you should contact the seller.
