The Flickering Display
Windows 11, particularly on modern laptops and high-end gaming monitors, supports a feature called Dynamic Refresh Rate (DRR). This feature allows the operating system to automatically switch your display’s refresh rate on the fly. For instance, it might drop the screen to 60Hz while you are staring at a static webpage to save battery power, but instantly boost it to 120Hz the moment you start scrolling or playing a video. While excellent for battery life, this constant, automatic switching can sometimes cause noticeable screen flickering, brief blackouts, or visual stuttering, especially if your specific monitor or graphics driver handles the transition poorly.
Locking the Refresh Rate
To ensure a completely stable, flicker-free visual experience and stop Windows 11 from automatically changing the display refresh rate, you must disable the dynamic setting and lock it to a static value.
Press the Windows key, type Display settings, and press Enter. Scroll down the main display panel and click on Advanced display. In the new window, look at the section labelled “Display information.” You will see a dropdown menu titled Choose a refresh rate. If DRR is currently active, this dropdown will likely say something like “Dynamic (60 Hz or 120 Hz).” Click the dropdown menu and select a static, fixed number. If you are on a laptop and prioritize battery, select 60 Hz. If you prioritize smooth scrolling and your monitor supports it, select the highest available static number (e.g., 120 Hz or 144 Hz). The screen may go black for a split second as it applies the lock, but Windows will no longer dynamically adjust the rate.
