AOC Dead Pixel Policy
AOC monitors follow the ISO 13406-2 Class II standard for pixel defects. Under this policy, a small number of defective pixels is considered within manufacturing tolerance and does not automatically qualify for a warranty replacement.
AOC's acceptable defect thresholds under Class II:
- Type 1 (bright dot): Up to 2 defects — within tolerance
- Type 2 (dark dot): Up to 2 defects — within tolerance
- Type 3 (partial bright sub-pixel): Up to 5 defects — within tolerance
A single dead pixel in a corner of the screen typically falls within AOC's acceptable range. Multiple defects, or a single defect near the center of the display, are more likely to result in a successful warranty claim — particularly when escalated directly to AOC support.
AOC AGON Gaming Monitors
AOC's AGON gaming monitor lineup (AG275QXN, AG274QZM, and similar) also operates under ISO Class II. There is no published zero dead pixel guarantee for AGON monitors. Higher-priced AGON models may receive more flexibility from AOC support for single-pixel defect cases, especially when the defect is documented to be in a high-visibility area.
AOC does not currently offer a separate premium pixel guarantee for any of its product lines — standard ISO Class II applies across the board, including AGON.
How to File an AOC Warranty Claim
- Run the dead pixel test and document the defect on both white and black solid color backgrounds.
- Note your monitor's model number and serial number (printed on the sticker on the rear panel).
- Contact AOC support through their regional support portal (aoc.com).
- Submit a warranty ticket with photos, your proof of purchase, and serial number.
- AOC typically responds within 5–10 business days.
If your defect count falls within ISO Class II tolerance, AOC support may decline a replacement. Providing clear documentation that the defect is in a high-visibility area — center of screen or within primary work zone — can improve your outcome. Escalating to a supervisor is also worth attempting for borderline cases.
Frequently Asked Questions
Does AOC replace monitors for one dead pixel?
Not automatically. AOC uses ISO Class II tolerance, which permits up to 2 dark and 2 bright pixel defects. A single dead pixel may not qualify unless it is in a particularly prominent location or the model is a higher-end AGON unit.
Does AOC have a zero dead pixel guarantee?
No. AOC does not currently offer a zero dead pixel guarantee on any of its monitor lines, including AGON gaming monitors.
How do I contact AOC for a warranty claim?
Visit aoc.com and navigate to the Support section for your region. You will need your monitor's serial number, proof of purchase, and clear documentation of the pixel defect. AOC offers online ticketing in most regions.
