A dead-pixel count does not decide the outcome by itself. If the seller’s return window is still open, check that first. If it is closed, read the exact warranty for your monitor model.
The seller, manufacturer, product condition, region, and defect type all affect what happens next. A seller may accept a return even when the manufacturer would allow the pixel under its warranty policy. A warranty denial does not mean you imagined the problem; it may mean the issue did not meet that policy’s terms.
Start with the deadline, not the pixel count
For a new monitor with a visible issue, timing matters. A seller return or exchange can be the practical first path while the listing’s deadline is still open. After that, the manufacturer’s written policy usually matters more.
Marketplace, third-party, open-box, refurbished, renewed, clearance, and final-sale listings may have different deadlines or claim handlers. Check the exact listing rather than assuming the store’s standard policy applies.

| You bought a separate protection plan | Read that contract for coverage, exclusions, deductibles, shipping, and claim handling |
Identify what you are actually seeing
People often use “dead pixel” for every screen problem. That can send you to the wrong policy or the wrong test. First classify the symptom.

| What you see | Where it belongs next |
|---|---|
| Bright, dark, or stuck colored dot | Use the Pixel Test, then read the exact pixel policy |
| Fixed bright corner or edge | Use the Backlight Bleed Test and read IPS Glow vs Backlight Bleed |
| Persistent taskbar, logo, or HUD shape | Use the Burn-In Test and check the exact OLED terms |
| Broad tint, clouding, or uneven gray | Use the Screen Color Test and document the issue during normal use |
| Flicker, lines, power, or port failure | Follow manufacturer troubleshooting or contact support |
| Crack, pressure mark, liquid, or impact | Check damage and protection-plan terms rather than ordinary pixel tolerance |
What bright, dark, and stuck pixels mean
A monitor pixel contains red, green, and blue subpixels. A bright dot may be a subpixel that stays on. A dark dot may be a subpixel that stays off. A stuck pixel or subpixel may remain fixed in one color.
The wording in a policy may not match the wording in a forum post. Look for terms such as bright dot, dark dot, full pixel, subpixel, stuck subpixel, cluster, adjacent defect, and combined total.
Run the Pixel Test before counting a tiny dot or contacting support. Test against more than one background so you can describe whether the point is bright, dark, or color-specific. The test helps you describe the issue; it does not decide whether the seller or manufacturer must accept a claim.
Why there is no universal dead-pixel number
Pixel policies can differ by:
- Bright versus dark defects
- Full pixels versus subpixels
- Total count
- Adjacent or clustered defects
- Native resolution
- Product family
- Premium guarantees
- Warranty period
- New versus refurbished condition
Current U.S. policies show why a generic number is unreliable. ASUS’s Zero Bright Dot program applies only to select displays and focuses on bright dots; it does not treat every dark dot the same way. ViewSonic publishes resolution-based pixel limits and explains that its warranty remedy may involve repair or replacement, including refurbished parts or components.

Treat those as examples of policy variation, not as rules for another brand. The row for your exact monitor is the one that matters.
How to find the policy for your exact monitor
- Copy the exact model number from the monitor, settings menu, receipt, or product page.
- Confirm that you are reading the U.S. policy.
- Find the manufacturer warranty or pixel-policy page.
- Confirm the product series and native resolution.
- Check bright, dark, full-pixel, subpixel, cluster, and combined-total language.
- Check the remedy: refund, repair, replacement, equivalent unit, or refurbished unit.
- Save the policy with the date you accessed it.
Do not rely on a generic brand table, forum post, or old screenshot when the current model policy says something different.
Seller return versus manufacturer warranty
The seller may decide whether the monitor is eligible for a return or exchange under the listing’s terms. The manufacturer may decide whether the issue meets its warranty definition of a defect. Those are separate decisions.
If the return window is still open and the issue bothers you during normal use, document it and contact the seller. If the return window is closed, use the exact manufacturer policy and describe the defect using its terminology when possible.
Do not publish or assume one universal return period. The exact listing, seller, condition, and purchase date control the deadline.
Do protection plans cover what the warranty does not?
A paid protection plan or service contract is separate from the manufacturer warranty. It may add coverage, but it may also duplicate the original warranty during the first year or exclude cosmetic and below-threshold pixel issues.
The FTC recommends checking the contract’s cost, coverage, exclusions, deductibles, fees, duration, administrator, and claim process before buying. FTC warranty guidance FTC service-contract guidance
Check whether the plan covers:
- Pixel defects below the manufacturer threshold
- Panel failure, lines, flicker, power, or port failure
- Image retention or OLED burn-in
- Accidental damage
- Deductibles, shipping, service fees, and replacement limits
- Repair, replacement, refurbished replacement, or payout
If it is not listed in the contract, do not assume it is covered.
Document the issue before the deadline
Test and document early. Do not wait until the last day of the return window, and do not press the panel, rub the dot, twist the chassis, open the monitor, or pry at the bezel before you have evidence.
Save:
- Model number and serial number
- Order number, purchase date, seller, and condition
- Return deadline
- Exact defect category
- Pixel count, color behavior, location, and clustering
- Normal-use photo and close-up evidence
- Test pattern, brightness, picture mode, room lighting, and test date
- Warranty page, protection-plan terms, support case number, and instructions
Use Document Damage for Warranty for the broader evidence workflow. This page is about which coverage may apply; that guide is about building the record.
Common situations
If the return window is still open and the issue bothers you during normal use, start with the seller. If the window is closed, move to the exact manufacturer policy. If the symptom is unclear, run the relevant ScreenDetect test before describing it in a claim.
One bright colored dot on a new monitor
Document it, check the seller deadline, and then check the bright-dot policy only if you are keeping the monitor past the return window. A premium bright-dot guarantee helps only when the exact model qualifies.
One dark dot below the published limit
The manufacturer may allow it even if you reasonably decide that you do not want to keep the monitor. If the seller return remains open, that is usually the simpler path.
Several dots close together
Count them, record their locations, and read the cluster, adjacent-defect, and combined-total language. The total count may not be the only rule.
Fixed bright corner, broad tint, or uneven gray
Use the relevant display test and document the issue during normal use. Do not force a backlight, glow, or uniformity problem into a dead-pixel count.
Persistent OLED taskbar, logo, or HUD shape
Run the Burn-In Test and read the exact OLED warranty or protection-plan terms. Do not describe it as a dead pixel.
Crack, pressure mark, liquid, impact, or opened monitor
Document the condition and check accidental-damage or protection-plan terms. Ordinary manufacturer warranty coverage may exclude physical or customer-caused damage.
What to do now
If the seller deadline is still open and the issue is unacceptable, document it and contact the seller today. If the window is closed, open the exact model warranty page and submit the evidence using its terminology.
If the policy is unclear, ask support for a written answer. If you still need to identify the symptom, run the relevant ScreenDetect test before filing the claim.
FAQ
How many dead pixels qualify for a monitor warranty?
There is no universal number. Policies may separate bright and dark dots, full pixels and subpixels, clusters, resolution, product family, and premium guarantees. Check the exact model policy for your region.
Does one dead pixel qualify for a return?
It may not qualify for a manufacturer warranty, but a seller may still accept a return or exchange while its return window is open. Check the listing terms and deadline first.
Is backlight bleed covered under warranty?
That depends on the seller, model, policy, and how visible the issue is under normal conditions. Backlight bleed is not decided by a dead-pixel count, so use the Backlight Bleed Test and the exact return or warranty terms.
What is the difference between a bright pixel and a dark pixel?
A bright dot usually describes a pixel or subpixel that stays on, while a dark dot stays off. Policies may treat them differently, so use the manufacturer’s terminology when you file a claim.
Do protection plans cover dead pixels?
Some may, but a protection plan is a separate service contract with its own exclusions, deductibles, fees, and claim process. Read the contract instead of assuming it improves the manufacturer’s pixel policy.
What should I document before returning a monitor?
Save the model, serial number, order details, seller, condition, return deadline, policy text, defect description, test settings, normal-use photos, close-up evidence, and any support case number.
