Screen flickering can be distracting, but it’s often due to straightforward issues. Start by updating your display drivers, as outdated drivers are a common cause. Go into Device Manager, locate your display driver, and select ‘Update.’ If you’re using an external monitor, check the cable connection—loose or damaged cables can cause flickering. Also, experiment with different refresh rates in display settings; sometimes, a higher or lower rate resolves flickering. Adjust brightness settings and disable adaptive brightness if it’s enabled, as this feature can sometimes interfere with stable display output. Finally, ensure you’re not running too many resource-intensive applications, as this can affect display performance on older computers.
