How Many Dead Pixels Qualify for Warranty?
Learn why dead pixel warranty rules vary by seller and manufacturer, and how to document pixel defects before asking for support.
Quick answer
There is no universal dead-pixel number that guarantees warranty replacement. Thresholds can differ by manufacturer, model, region, panel class, pixel type and seller policy. Confirm and document the defect, then check the exact policy for your product.

Why the threshold varies
Policies may count dark pixels, bright pixels and clusters differently. A seller return window may also be more flexible than a manufacturer pixel-defect warranty.
Document the defect by type
Clean the screen and compare white, black, red, green and blue. Record whether each point is dark, bright or colored, its approximate location and whether multiple points form a cluster.
Use the correct policy
Search the support page for the exact model and purchase region. This guide cannot interpret a warranty contract or promise eligibility; the seller or manufacturer makes the final decision.
How to verify it
- Confirm each suspected pixel on several fullscreen colors.
- Count dark, bright and colored points separately and note any clusters.
- Record the model, serial number, purchase date and realistic photos.
- Check the seller return terms first, then the manufacturer pixel policy.
