Dead pixel possible after 3 weeks of usage?

[vigu360]

I bought a 2011 iMac and after 3 weeks and after the graphic display software update there seems to be a dead pixel on my screen. I'm wondering whether it's a dead pixel or dust? It's so tiny that if I take a closer look seems like dead pixel. Can you guys share some insights whether the display does get dead pixels by usage and not manufacturer defect?

no I didn't but upgraded the video driver. Is there a tool to release it or something?

I had the exact same problem, after 2 weeks of use there was one dead pixel. Now all of a sudden it seems to be gone like it was never there

I've noticed that the iMacs are really good at getting rid of dead pixels by themselves. Including the iPads. In the store I work we tend to leave them on for a couple of weeks just to repair themselves. No one quite understands IPS displays 😛
