Dead Pixel Test · Guide

Dead Pixel Warranty Policy

Whether one faulty pixel qualifies for repair or replacement depends on the manufacturer’s pixel policy — not on this site. This page explains how those policies generally work and what to prepare; it is not legal advice and grants no warranty.

How pixel policies generally work

Most manufacturers publish a pixel policy that tolerates a small number of defective pixels per panel before a screen qualifies for repair or replacement. Thresholds differ by brand, panel class and whether the screen is new or refurbished — premium lines are sometimes stricter.

Policies usually distinguish dead, stuck and bright pixels and count them separately across zones. Look up the published policy for your exact model before filing any claim; support will ask for it.

What to prepare before you claim

Run the full nine-colour pass on the main test page at your normal brightness, confirm the suspect on both black and white, and rule out dust by tilting the screen and wiping gently with a soft, dry microfibre cloth.

Mark the approximate spot on the screen map and download the text summary. It is a “User-reported visual inspection” note with the date and colours inspected — your record of what you saw, not a diagnosis, repair certificate or warranty decision by itself.

What not to expect

This site cannot diagnose your display, repair pixels or decide claims. It offers no flashing fixer and no pressure or massage instructions, which can damage a panel.

Keep expectations honest: a single faulty pixel on an otherwise fine panel is often within tolerance. If the policy excludes you, the practical paths are living with it, returning within the retailer window where one exists, or replacing the panel at your own cost.

Honest limits: this guide helps you identify possible display problems with your own eyes. It cannot repair hardware pixels, diagnose your display automatically, or decide warranty claims. Read the limits.

Guide FAQ

Does one dead pixel mean a free replacement?

Not necessarily. Most pixel policies tolerate a few defective pixels per panel; whether one qualifies depends on the published policy for your exact model.

Does the inspection summary prove my claim?

No. It records what you reported seeing with the date and colours inspected. It does not capture, verify or prove a physical defect.
