The tester, exerciser and guides on DeadPixel are provided “as is” for general information. We work to keep them accurate, but we make no warranties of any kind — a few specific cautions apply:

A test result is evidence, not a verdict. A dot that fails on every color here is a strong indication of a panel defect — but the tester reports what your browser paints. GPU quirks, screen-record overlays, blue-light filters and remote-desktop software can all imitate or mask defects. Confirm on a second device or a different input before you file a claim or attempt a repair.

The exerciser flashes on purpose. It produces rapid, bright color changes in a small region — that is precisely what can trigger photosensitive seizures in susceptible people. It stays behind an opt-in consent prompt for that reason. Do not use it if you or anyone watching has epilepsy or sensitivity to flashing images, and stop immediately if you feel unwell. The size and rate caps exist to reduce risk; they don’t eliminate it.

Physical fixes carry physical risk. The pressure and cleaning techniques described in the fix guide can damage a panel permanently — pressure marks are themselves a defect class. Follow them at your own risk, and prefer the zero-risk flashing method first. We are not responsible for damage caused by attempting any described fix.

Policies change. Brand warranty details in the warranty guide reflect each maker’s published position at time of writing and vary by model line and region. The binding text is always the policy attached to your specific product — verify before relying on it.
