Screen flickers, cable or panel?
Four suspects, in order of likelihood: cable, driver, refresh-rate mismatch, panel itself. Rule them out one by one.
Try this first
- 1(If the flicker comes with crashes or black screens, start with the GPU-driver-crash topic under performance first; the driver steps live there.)
- 2External monitor: try a different cable (HDMI or USB-C). Most flicker lives in a cable or a dock port.
- 3Update the graphics driver (Windows Update or NVIDIA/Intel app). Reboot.
- 4Check refresh rate in Settings > Display. Some docks push 4K at 30 Hz, which causes a wobble.
- 5On the laptop's own screen: always, or only when moving? Movement-related often points at a loose flat cable near the hinge.
When to bring us in
External monitor flickers across multiple cables and docks? The panel or its electronics could be it. Warranty claim if under 2-3 years old.
