If you have a dead pixel on an AOC monitor, here is the short answer: AOC uses ISO Class II tolerance, which permits up to 2 dead pixels before a warranty replacement is guaranteed. A single dead pixel — particularly in a corner — may be declined. But a centre-screen defect or multiple defects gives you a solid case, especially if documented clearly.
Run the dead pixel test above before contacting AOC support. Photos taken during the test (on white and black backgrounds) are exactly what AOC warranty requires.
AOC's Dead Pixel Threshold — What the Numbers Mean
AOC follows ISO 13406-2 Class II across all product lines, including AGON gaming monitors. The permitted defect counts before AOC is obligated to replace your screen:
| Defect type | What it looks like | AOC tolerance |
|---|---|---|
| Type 1 — bright dot | Always-on white or coloured dot | Up to 2 |
| Type 2 — dark dot | Always-off black dot | Up to 2 |
| Type 3 — partial sub-pixel | Dim or partially lit sub-pixel | Up to 5 |
What this means in practice: One dark dead pixel anywhere on the screen technically falls within AOC's tolerance under ISO Class II. AOC support may still approve a replacement as a goodwill exception — particularly if:
- The defect is in the centre of the panel or within your primary work area
- The monitor is a higher-priced AGON model (AG275QXN, AG274QZM, etc.)
- You have documented proof and are persistent with escalation
AOC AGON Gaming Monitors: Any Special Policy?
AGON monitors carry no zero dead pixel guarantee — they follow the same ISO Class II standard as the budget AOC line. This is a meaningful difference from competitors like LG (which offers a zero bright pixel guarantee on OLED models) and ASUS ROG (which offers limited zero-defect coverage on select ProArt models).
If you own an AGON Pro or high-end AGON unit with a centre-screen dead pixel, AOC support is more likely to make a goodwill exception than on a budget AOC 24G2 — but this is not published policy, and you may need to escalate beyond the first support agent.
How to File an AOC Warranty Claim
AOC typically responds within 5–10 business days. If your ticket is declined and you believe the defect genuinely impacts usability, request escalation to a senior technician and emphasise the defect's location relative to your primary viewing area.
AOC vs Other Brands on Dead Pixel Coverage

| Samsung | ISO Class II | No |
Frequently Asked Questions
Does AOC replace monitors for one dead pixel?
Not automatically. ISO Class II allows up to 2 dark and 2 bright defects. A single dead pixel in a corner will likely be declined. A single defect at screen centre on a high-end AGON model is worth claiming — document it clearly and be prepared to escalate.
Does AOC have a zero dead pixel guarantee?
No. AOC does not currently offer a zero dead pixel guarantee on any product line, including AGON Pro gaming monitors. Standard ISO Class II tolerance applies across the board.
Is AGON covered better than standard AOC monitors?
Officially, no — same ISO Class II policy. In practice, AOC support may show more flexibility on expensive AGON models for goodwill replacements, but this is not guaranteed.
How do I contact AOC for a warranty claim?
Visit aoc.com → Support → select your country → submit a ticket. You will need your serial number, proof of purchase, and photos of the defect on white and black backgrounds. AOC offers online ticketing in most regions; phone support availability varies by country.
What if AOC declines my claim?
Request escalation to a senior support agent. Provide detailed documentation of the defect location relative to screen centre. If the monitor was purchased from a retailer, you may also be able to pursue a return or exchange through the retailer's own policy within the return window.
