Will a monitor be replaced for one dead pixel?

Usually not under warranty. Most published policies tolerate around 5 dark sub-pixels — including Dell's zero-bright-pixel program. One dark pixel is a good reason to use the retailer's return window instead.

Which monitor brands have a zero bright dot policy?

From the brands' own pages: Dell's Premium Panel Exchange lines (whole warranty), HP Z series and Series 7 Pro, ASUS ProArt PA (36 months) and ROG Swift PG (first 12 months), AORUS (first 12 months), BenQ's zero-bright-dot models and Acer's BM series. Lenovo ThinkVision P and T Gen-40 owners should contact Lenovo for even one bright pixel.

Do OLED monitors have different pixel policies?

Often, yes. ASUS excludes its OLED models from zero bright dot (up to 3 bright for 24 months), Gigabyte's dot table covers LCDs only, and Philips' 42-inch OLED manual allows zero bright but up to 35 dark sub-pixels. Check the policy for your exact model.

How do I make a dead pixel warranty claim?

Run a full-screen colour test, photograph each defect on the colour that shows it best, and note its position. Count bright and dark defects separately, then contact the brand's support with the serial number and proof of purchase. Within the retailer's return window, a return is usually faster.

What is ISO 9241-307 Class 1?

ISO 9241-307 is the standard for testing electronic displays, including pixel-defect classes. Class 1 is the strictest commonly used class. The standard is a paid document; AOC and Lenovo describe Class 1 in their own policies, and most brands don't state a class at all.

Dead Pixel Warranty Policies by Monitor Brand

We checked 14 monitor brands' own websites. Dell replaces a display for a single bright pixel during the whole warranty on its Premium Panel Exchange lines (UltraSharp, P, newer S, G and most Alienware). HP Z series, ASUS ProArt and BenQ's zero-bright-dot models also allow zero bright pixels; ASUS ROG Swift and AORUS do for the first 12 months. Most other policies tolerate 2–3 bright and about 5 dark sub-pixels before replacing anything, and Samsung (US), LG (current US models) and Apple publish no number. Inside a retailer's return window, returning is usually simpler than a warranty claim.

How to read these policies

Bright beats dark. Almost every brand is stricter about bright (always-lit) defects than dark ones, because a bright dot on a dark image is far more visible. Even Dell's zero-bright program tolerates up to 5 dark sub-pixels.

Sub-pixels vs pixels. Most policies count sub-pixels (one red, green or blue element). A full-pixel defect — all three sub-pixels stuck — is usually not tolerated at all. ViewSonic counts whole pixels.

Zero-bright-dot promises are narrower than they sound. They often apply only to premium or creator lines, and on ASUS ROG Swift and AORUS only for the first 12 months.

ISO 9241-307 is the international standard that defines pixel-defect classes, but the text is paid and few brands cite a class. AOC states Class 1 as its threshold and Lenovo says its monitors meet Class 1; the class descriptions here are those brands' own summaries.

Check the return window first. A retailer return doesn't depend on pixel counts at all, which makes it the easiest route for a new monitor with any visible defect.

Policies vary by region and change over time. Each row links to the page we read; confirm on your region's support site before you claim.
