How to Spot Dead Pixels in New Electronics Before You Buy

# Tips for Checking Dead Pixels When Buying New Electronics

- **Test with Full Screen Colors:** Make your screen completely white, black, red, green, or blue using paint, a website, or full-screen images (F11). This makes dead or stuck pixels easier to spot.
- **Use Multiple Colors:** Cycle through different colors to identify anomalies like stuck pixels.
- **Official Standards:** Dead pixels are normal; displays are rated by ISO 13406-2 standards, with Class I having no dead pixels, and Class II allowing a few. Avoid Class III or IV.
- **Return Policies Matter:** Buy from vendors with good return policies; many allow returns without reason within a certain period, especially online.
- **Check Before Purchase:** Inspect for dead pixels on arrival; consider using dedicated test videos on YouTube or specialized websites like [Eizo Monitor Test](https://www.eizo.be/monitor-test/).
- **Be Vigilant During Travel:** When packing fragile electronics or screens, test immediately after unpacking to detect potential damages from transit.
- **Know Your Rights:** Minor defects like dead pixels are often considered returnable issues, especially under regulations like EU’s "free from minor defect" rule.
- **Avoid Accepting Faulty Displays:** Some stores claim an "acceptable limit," but many argue zero dead pixels should be standard. Don’t settle—return if defective.
- **Post-Black Friday Strategies:** Wait until after sales to buy electronics at a better price and ensure they've been thoroughly checked.
- **Additional Tips:** For laptops, monitors, or TVs—examine carefully upon receipt. If defective, contact customer service or file chargebacks if necessary.
