A laptop screen flickers primarily due to one or more of the following causes: incompatible applications running on the system, outdated or corrupted display drivers, loose or damaged internal connections, incorrect refresh rate settings, or underlying hardware problems such as a failing graphics card or damaged screen. Additionally, other factors like overheating, power supply fluctuations, or software conflicts may also lead to flickering. Many times, the issue can be diagnosed by checking if the flickering continues when certain apps (like Task Manager) are open or when booting in Safe Mode. Hardware-related flickering often worsens with screen movement, indicating cable or connection issues. Updating drivers, adjusting refresh rates, checking connections, and uninstalling recent apps or updates are common troubleshooting steps to fix the flickering.
