Computer Graphics Display Output: contaminated video connector. Residue on signal contacts disrupts the display connection.

The distinguishing clue

Video is intermittent at a visibly contaminated connector.

Checks before an assessment

Record the affected display, port, resolution and refresh rate. Compare a known cable and display if the connectors are sound; stop load tests if excessive heat accompanies artefacts.

Stop point: Stop high-load testing if artefacts are accompanied by excessive heat or burning smell.

Workshop confirmation and repair

Device-level check: Compare another cable and display, inspect temperatures and separate software from hardware rendering.

Targeted check: Inspect the unpowered connector and compare an undamaged cable. If confirmed: Clean serviceable contacts or replace the contaminated connector.

Repair boundary: Repair driver state or the confirmed graphics card, connector or board path.

Related cause to rule out

When signal loss begins after a cable pull or impact and the connector looks deformed, also consider Computer Graphics Display Output: physical graphics-connector damage before choosing a repair.

Checks after the work

After repair or replacement, check native resolution, multiple outputs, video playback, graphics load and restart.
