Black screen after changing refresh rate on Windows PC

If you encounter a black screen issue after changing the refresh rate on your Windows 11/10 PC, this article will help you. We will share some effective troubleshooting steps to help you resolve this issue. By default, desktop monitors have a refresh rate of 60 Hz. You can increase the refresh rate for better game or app performance, but going beyond what your monitor supports can cause display issues or screen flickering.

Windows itself restricts setting refresh rates that the monitor does not support, but third-party applications may bypass this restriction. If the system's graphics settings are adjusted, the screen may go black after startup and the desktop environment cannot be entered. This article will guide you on how to handle accidentally changing your monitor's refresh rate to an unsupported one.

Why is my screen black at 144 Hz?

The main reason for the black screen problem after changing the monitor refresh rate is usually to select a refresh rate that is higher than the monitor's refresh rate capability. In addition, hardware mismatch, graphics driver issues, software conflicts, or incorrect display settings may also cause a black screen on Windows 11/10 PC. Before adjusting the refresh rate, always make sure that both your graphics card and monitor support the desired refresh rate.
