Computer Graphics Display Output: graphics output power fault. The output stage or attached display lacks a required supply or enable.

The distinguishing clue

Video stays absent on the affected path despite correct cable, input and settings.

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: Identify the failed powered stage and verify its supply and control path. If confirmed: Repair the confirmed output or display power stage.

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

Related cause to rule out

When verified graphics hardware, display and cable do not restore the affected board output, also consider Computer Graphics Display Output: graphics board signal-path fault before choosing a repair.

Checks after the work

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