Laptop HDMI Output Port: fractured conductor. Repeated flexing breaks a wire or board trace under its insulation.

The distinguishing clue

The attached device cuts out at a repeatable cable or plug position.

Checks before an assessment

Check the monitor's selected input and compare an undamaged, compatible HDMI cable. Note whether audio and video fail together.

Stop point: A loose HDMI plug can lever pads away from the motherboard.

Workshop confirmation and repair

Device-level check: Verify the monitor input and cable, compare another display and inspect the HDMI pins and shell.

Targeted check: Perform a gentle movement test and continuity check with power removed. If confirmed: Replace the cable or repair the confirmed trace and remove the mechanical strain.

Repair boundary: Repair the connector or signal path only after graphics settings and the external equipment are excluded.

Related cause to rule out

When movement or light plug pressure changes the fault, also consider Laptop HDMI Output Port: loose connector before choosing a repair.

Checks after the work

After repair or replacement, check several resolutions, audio, hot-plug detection and a sustained display test.
