Pattern to record: Lower settings work while native high-bandwidth modes flicker or blank.

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 the cable cannot carry the selected resolution, refresh and colour format reliably.

Display-path checks

1. Compare native and lower refresh rates, different certified cables and another graphics source.
2. Calculate required bandwidth and compare a short certified cable.

Handling and electrical safety

Stop testing if the monitor emits a burning smell or flashes from its power section. Repeated reconnects do not repair a marginal or mislabelled cable.

Image and input verification

If the checks support this cause, use a verified cable and configure a supported signal format. 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.
