new laptop, dead pixel - acceptable?
We've just bounght a new laptop/notepad (NEC), but discovered that it has a single dead pixel in the middle of the screen.
We're taking it back now to the local store with the expectation that it will be swapped for another machine but, not being very up with notepad issues, I was just curious to learn from others:
1. Are dead pixels common on laptop screens?
2. Are dead pixels strictly a hardware failure, or can they be software related?
3. Can dead pixels be repaired, or is it always a case of swapping the screen for a new one?
4. Can we expect that, over time, dead pixels on our laptop will 'naturally' increase?
Thanks - just curious!
