Does one dead pixel qualify for a warranty replacement?

Sometimes, but not universally. Eligibility depends on whether the defect is bright or dark, its location, the model, region, seller return policy and any zero-bright-dot coverage.

What evidence should I collect for a dead pixel claim?

Record the model, serial number, purchase date, defect count and locations. Photograph the full display and a close view on suitable solid-color backgrounds, then keep the original files and receipt.

Is a stuck pixel the same as a dead pixel?

Everyday language overlaps, but warranty documents often distinguish bright subpixels that remain on from dark subpixels that remain off. Use the manufacturer's definitions when filing a claim.

Dead Pixel Warranty Policies Explained

Start with the seller return window

If a new display has a distracting pixel defect, read the seller’s return or exchange terms before opening a manufacturer warranty claim. A return window may be simpler and broader than the manufacturer’s pixel threshold. Do not wait until the last day: record the issue, packaging condition and purchase date immediately.

Seller policies, manufacturer warranties and statutory consumer rights are separate. A manufacturer threshold does not automatically remove rights provided by local law, and this guide is not legal advice. Use the policy for your exact model, purchase country and purchase date.

Learn the policy language

Pixel, subpixel and partial defect

A full pixel normally contains red, green and blue subpixels. Warranty documents often count subpixel defects rather than only complete pixels. A tiny partial anomaly may be treated differently from a full subpixel defect. This distinction explains why the number you see in a policy may not match an informal “dead pixel” count.

Bright, dark and stuck

A bright subpixel remains illuminated when it should be dark. A dark subpixel fails to illuminate when it should be visible. “Stuck pixel” is common informal language, but support teams may require classification using their own bright/dark definitions and test backgrounds. A red, green or blue point can be a subpixel defect rather than a complete pixel.

Zero bright dot does not mean zero defects

Zero Bright Dot or similar coverage often applies only to bright defects, eligible models, a particular time period or specific regions. Dark defects may use a different threshold. Never infer full zero-defect coverage from the product-line name alone.

Policies changeThe examples below illustrate how policies differ; they are not a warranty decision. Confirm the current official page for your exact model and country before buying or filing a claim.

How major manufacturer policies can differ

Dell: Dell’s current display pixel guidance says eligible Premium Panel Exchange displays have zero tolerance for bright pixels or bright subpixels during the applicable warranty period. Dark defects and standard displays use model-specific criteria. Dell also distinguishes partial subpixel anomalies.
ASUS: ASUS policy pages show that general, Zero Bright Dot and professional-series coverage can use different bright/dark criteria. Models and rules vary by region, and ASUS directs buyers to the relevant model warranty information.
BenQ: BenQ states that standard coverage applies when defects exceed the published specification. Selected models or regions may include Zero Bright Dot coverage, while standard thresholds and evidence requirements differ.
LG: LG publishes regional pixel policies with allowable bright and dark defect criteria. The thresholds shown by LG support pages differ by market and sometimes by resolution or product category.

These differences are why a search result saying “five pixels are allowed” is not enough. It may refer to another model, old policy, different defect class or different region.

Check and document the defect correctly

Clean the screen and remove a screen protector only if doing so is safe and permitted.
Set native resolution, disable overlays and use a comfortable normal brightness.
Run the fullscreen dead pixel test on black, white, red, green and blue.
Confirm the dot stays in the same physical location after changing colors, apps and inputs.
Record whether it appears bright, dark or colored and count each distinct location.
Take one photo showing the full display and another close view. Avoid camera exposure that creates false bright points.
Save the model, serial number, receipt, purchase date and original photo files.

Do not press, rub or tap the panel. Physical manipulation can damage the display and complicate a warranty claim.

How to make the claim

Open the official support page for your purchase region and locate the exact model’s warranty terms.
Check bright and dark criteria separately, including any central-zone rule, clustering rule or coverage period.
Contact the seller first when the product remains inside its return or exchange window.
For manufacturer support, describe the defect neutrally and provide the requested test photos and identifiers.
Keep the case number and written response. If support rejects the claim, ask which policy section and defect count were applied.

Frequently asked questions

Does one dead pixel qualify for replacement?

Sometimes. A single bright defect may qualify under eligible zero-bright-dot coverage or a seller return policy, while one dark defect may remain below the manufacturer threshold. Check the exact terms.

Can I use a browser test as warranty proof?

It can provide clean test backgrounds and help document location, but it does not make the warranty decision. Support may request its own diagnostic procedure and photographs.

What if the policy changed after I bought the display?

Keep the warranty document supplied with the product and the terms available at purchase. Ask support which version applies to your serial number, region and purchase date.
