FAQs
How do I test a dead pixel before a warranty claim? +
Use full-screen solid colors and inspect the same point on white, black, red, green, and blue. A dead pixel usually stays dark while a stuck pixel may remain colored.
Should I return a monitor for one dead pixel? +
For a new monitor, use the return window first if the defect bothers you. Warranty policies vary, but retailer return periods are usually the cleaner path.
Should I buy a new monitor after warranty denial? +
Only if the defect affects real use and repair or return is unavailable. One edge pixel may be tolerable; a central defect is harder to ignore.
Repair path
