    Create or download an image that's all white. Make it full screen. Look for pixels that aren't white.

    Is that easy to do? Spot the incorrectly colored pixels, I mean?

    I'd use black and white as a minimum. Screen brightness all the way up too

    If you don't know how to spot dead pixels, and don't seem to really even know what you're looking for, why are you doing this to yourself? We've all seen these symptoms before with screens, battery life, CPU temps, etc. - you're headed for computer hypochondria. Just enjoy your new computer.

    Seriously, if the OP hasn't noticed any dead pixels yet then they can't possibly be that annoying of a problem, if they exist.

    My monitor has a dead pixel towards the bottom left. It looks blue when everything else is white. I guess that means the red and green pixels are out, so actually I have two dead pixels. I only notice it every couple of months. It looks like the smallest possible speck of dust. I've tried pointing it out to some other people and they can't even see it. I'd be nuts to be upset about this problem.
