Pattern to record: One input fails or reacts when the plug is moved.

Separate the panel from the source

Record resolution, refresh rate, colour mode and whether variable refresh is enabled. These determine link demand. Backlight and LCD edge-bond checks below apply only to LCD models, not to an OLED display. One possible explanation is that connector pins or board joints no longer carry stable high-speed data.

Display-path checks

1. Compare native and lower refresh rates, different certified cables and another graphics source.
2. Compare inputs and inspect the connector and protection devices.

Handling and electrical safety

Stop testing if the monitor emits a burning smell or flashes from its power section. A heavy cable can tear new joints unless strain is relieved.

Image and input verification

If the checks support this cause, replace the damaged port or repair its board connection. Verification should cover native refresh, lower refresh, variable refresh, colour, sleep and sustained gaming.

For an assessment of your gaming monitor, contact AEPC in Burswood or call 027 908 8880. Provide the model and the conditions that reproduce this problem. Workshop visits are by appointment.
