1. Driver issue: - Outdated or damaged display drivers may cause screen flickering. Drivers are the bridge between the operating system and graphics card, responsible for managing and optimizing graphics display.
2. Hardware malfunction: - Graphics card issue: Graphics card hardware malfunction, such as memory damage or poor heat dissipation, may cause screen flickering- Screen cable issue: Loose or damaged screen cables may also cause screen flickering- Power adapter or battery issues: A faulty power adapter or aging or damaged battery may also cause screen flickering- Screen aging or damage: Long term use may cause screen aging or damage, leading to screen flickering.
3. Improper setting: - Incorrect screen refresh rate setting: A low refresh rate may cause the screen to flicker- Power management settings: Energy saving mode may reduce graphics card performance, leading to screen flickering.
4. Magnetic field interference: Placing the computer in a strong magnetic field environment may cause the screen to flicker.
5. Software Conflict: Some applications or system services may conflict with graphics card drivers, causing screen flickering.
6 HDR mode incompatible:- HDR (High Dynamic Range) mode may be incompatible with laptop hardware or drivers in some cases, resulting in screen flickering. 2、 Solution method
1. Update Driver Program: - Use software such as "Driver Life" to automatically detect and update graphics card drivers- Visit the official website of graphics card manufacturers (such as NVIDIA, AMD, or Intel) to download and install the latest drivers.
