Dead Pixel Warranty — Is Your Screen Covered?

Whether a dead pixel qualifies for warranty replacement depends on the brand, the number of defects, and — critically — how quickly you report it.

Most manufacturers follow ISO 13406-2 Class II, which permits a small number of pixel defects and only covers warranty replacement above a minimum threshold — typically 3–5 bright dead pixels. Dell's Premium Panel Guarantee and Apple's case-by-case policy are the most lenient. The single most effective action is to report the defect to your retailer within the first 30 days.

The ISO 13406-2 Standard — Why One Dead Pixel Often Isn't Enough

Display manufacturers defend their warranty thresholds by citing ISO 13406-2 (now ISO 9241-307), an international standard that classifies LCD panels by allowable pixel defect counts. The standard defines four classes:

Class	Bright defects / M px	Dark defects / M px	Typical products
Class I	0	0	Medical, military, aviation displays
Class II	2	2	Consumer monitors, laptops, TVs (most common)
Class III	5	15	Budget panels, commercial signage
Class IV	50	150	Industrial / outdoor panels

Under Class II, a 4K monitor (8.3 MP) can technically have up to 16 bright defects and still be within specification. This is the legal basis on which manufacturers decline single dead pixel claims. However, the ISO standard describes what is technically permissible during manufacturing — it does not prevent a brand from offering a more generous warranty, which is exactly what Dell, Apple, and some ASUS ProArt lines do.

Dead Pixel Warranty by Brand

Apple	Pro Display XDR: case-by-case, typically generous	Case-by-case — single bright pixel often approved within 30 days	MacBook: same case-by-case policy; Genius Bar discretion	Lenient
Samsung	Class II — typically 3–5 bright pixels required	Case-by-case — single bright near center often approved	Standard Class II threshold	Standard
LG	UltraGear: Class II (3–5). Some pro displays more lenient	Case-by-case; report within 30 days for best outcome	Standard Class II	Standard
ASUS (ROG / ProArt)	ROG: 3-pixel bright threshold. ProArt: more lenient on content creator lines	N/A	Standard Class II threshold	Standard
HP	EliteDisplay: more lenient. Consumer: Class II (5+ defects)	N/A	EliteBook: lenient. Omen/Victus/consumer: Class II	Standard
Sony (Bravia / Xperia)	N/A	Case-by-case; Xperia support contact recommended within 30 days	N/A	Standard
Google Pixel	N/A	1-year warranty; single bright pixel typically approved; Preferred Care extends to 2 years	Pixelbook: case-by-case	Lenient

Policies change. Check the manufacturer's current warranty documentation for the most accurate thresholds — particularly for newer product lines.

The Retailer Return Window — Your Best Option

The most reliable path to replacement for a single dead pixel is the retailer return window — typically 14–30 days from purchase. During this period, most major retailers treat a visible dead pixel as a legitimate reason for a no-questions exchange, regardless of the manufacturer's ISO threshold.

Amazon

30 days

Return as "defective" — no restocking fee

Best Buy

15–30 days

My Best Buy+ members get extended window

Apple Store

14 days

Genius Bar also available for assessment

Test any new display immediately — within the first 24–48 hours of unboxing. Use the dead pixel test before you have used the device long enough to feel attached to it. Returning a monitor after one day is far easier than after three weeks.

How to Make a Dead Pixel Warranty Claim — Step by Step

1
Run the test and document
Use the dead pixel test tool on a white background and photograph the defect clearly. Note the date it first appeared and that no physical damage occurred. Take at least three photos: white background (shows dead pixels), black background (shows stuck pixels), and one showing the pixel location relative to the screen center.
2
Check your coverage status
Find your serial number (usually under the device or in Settings → About) and check warranty status at the manufacturer website. Confirm whether you are within the standard warranty, an extended plan (AppleCare+, Samsung Care+), or the retailer return window.
3
Contact the retailer first if within the return window
Retailers (Amazon, Best Buy, Currys, Apple Store) are more flexible than manufacturer warranty channels within the first 14–30 days. 'I received this device with a dead pixel' is a simpler conversation with a retailer than a warranty claim with a manufacturer. Always try the store first.
4
File the manufacturer warranty claim
Contact the manufacturer support channel — online chat or phone, not email. Have your photos, date of purchase, and serial number ready. Describe the defect as a pixel defect (not a stuck pixel or manufacturing defect — let them categorise it). Ask specifically whether the defect qualifies for warranty service.
5
Escalate if the first agent declines
If the support agent cites the minimum pixel threshold and declines, ask to speak with a senior technician or escalate to the device quality team. A single bright pixel near the center of an expensive display is genuinely disruptive — describe your use case (design work, coding, gaming) and the impact of the defect. Many first-level declines are reversed on escalation.

Special Cases That Almost Always Qualify

Dead pixel line (full row or column)

A row or column driver failure producing a full line of dead pixels is a severe manufacturing defect. Report it to the manufacturer — it almost always qualifies for replacement regardless of the standard pixel threshold.

Dead pixel at screen center

A pixel defect directly in the center of the usable screen area is significantly more disruptive than one at the edge. Frame your claim around usability impact — "it is directly in the center of my work area" — rather than the pixel count.

Multiple defects on a new device

Two or more pixel defects appearing within days of receiving a new device points to a manufacturing batch issue. Document all defects together and claim them as a group — the total count is more likely to meet the threshold.

Before You Claim — Try the Fix Tool First

If the pixel is stuck (colored) rather than dead (black), a 10–20 minute session with our stuck pixel fix tool sometimes resolves the issue without any warranty claim. Try two sessions before contacting support — and crucially, do not attempt physical pressure methods before claiming, as evidence of tampering can complicate your case.

First: confirm the defect with a test.

Photograph the defect on a white background — that image is your warranty claim evidence.

Frequently Asked Questions

Can I return a monitor for one dead pixel?+

It depends on the brand and when you bought it. Within the retailer's return window (usually 14–30 days), most stores will exchange for a single visible dead pixel — especially near the screen center. After that window, you're dealing with the manufacturer warranty, which typically requires 3–5 defects. Dell's Premium Panel Guarantee is the exception: one bright pixel qualifies at any time within the warranty period.

Does Apple replace iPhones for a single dead pixel?+

Apple doesn't publish a minimum threshold. In practice, a single bright stuck pixel near the center is often enough for a Genius Bar technician to approve a replacement display, especially within the first 14–30 days. One dark dead pixel near the edge is less likely to be approved. AppleCare+ strengthens your case significantly.

What is the ISO 13406-2 dead pixel standard?+

ISO 13406-2 (updated as ISO 9241-307) classifies displays into pixel-defect classes. Class II — the standard most consumer monitors and TVs carry — permits approximately 2 bright and 2 dark defects per million pixels. On a 4K panel (8.3 MP), that is roughly 16 technically permitted defects. Manufacturers use this standard to justify their warranty thresholds.

Does a dead pixel warranty cover stuck pixels too?+

Yes. Manufacturer warranties cover all pixel defects — dead (permanently black), stuck (fixed color), and hot (permanently white). The warranty does not distinguish between types; it counts total defective pixels against the threshold.

Is a dead pixel covered if the screen is cracked?+

No. A cracked screen indicates physical damage, which voids the display defect warranty on all brands. If the glass is intact but pixels are dead underneath it — from impact that didn't crack the outer glass — this is a grey area. Report it as a pixel defect (not mentioning the impact) if the glass is visibly undamaged.

Will a manufacturer repair a dead pixel line under warranty?+

Almost certainly yes. A full horizontal or vertical line of dead pixels indicates a row or column driver failure — an obvious manufacturing defect. This typically qualifies for warranty replacement regardless of the brand's standard pixel count threshold. Document it with photos and report it promptly.
