How to Document Screen Defects for Warranty
Create useful notes and photos for seller or manufacturer support when reporting dead pixels, bleed, lines or screen defects.
Quick answer
Useful warranty evidence shows a repeatable screen symptom under realistic conditions. Record the model, serial number, purchase date, test page, color or pattern, brightness, screen location and whether the issue appears after a restart or on another source.

Write a reproducible description
State what you see, where it appears and which test reproduces it. Use terms such as fixed dark pixel, bright colored pixel, edge light, vertical line or repeated touch gap instead of a vague description.
Take honest supporting media
Use a focused photo that includes enough of the screen to show location. Avoid extreme exposure that exaggerates black levels. A short video can show motion, flicker or touch failures that a still image cannot.
Keep policy details separate
Seller returns and manufacturer warranties may use different deadlines and pixel thresholds. Evidence supports the request, but only the applicable policy determines eligibility.
How to verify it
- Record model, serial number, purchase date and current settings.
- Repeat the symptom with the most relevant test page.
- Capture a realistic photo or short video plus the defect location.
- Contact the seller or manufacturer with the concise reproduction steps.
