Good day,

For those of you that have experience with dead pixels, are they always manufacturing defects present from the beginning, or can they appear over time?

Basically, if I buy a monitor in store and verify that it has no dead pixels, am I (relatively) safe?
 
Dead pixels can appear over time. There is no guarantee that your display will never develop dead pixels.

I suppose I've been very lucky that my old 19" Planar PX191 monitor that I bought back in 2002 has never developed any issues whatsoever. Still using it today as a secondary monitor (right now in fact). However, this was a top of the line monitor back in 2002. I paid $650 for it when it was on sale. I think most 19" monitors back then were priced at $300 - $450.
 
LCD's can develop dead or stuck pixels at any time. I've only had one on a laptop that developed three dead pixels, after several years of use.
 
Just how common are dead pixels? The only thing keeping from ordering a LCD monitor from Newegg is their dead pixel policy and I'm curious just what my odds are of my monitor having this problem.

Depends on the brand. Also the reviews of a monitor are a pretty good sample to roughly determine the percentage of that model that has a dead pixel(s).
 
I had one show up on a monitor I just got a few days after getting it. When I got the monitor I checked all the colors and all were present. A few days later I noticed one near the edge of the screen and know it wasn't there before. It is a single pixel near the edge and doesn't draw attention to itself so it isn't returnable. It is unfortunate but I can live with it.

Back a few years ago I had a monitor I used for a couple years and then it suddenly started loosing pixels near the center of the screen. It was weird they were all adjacent to each other and over the course of a month or so died until there was a big splotch of dead pixels. The monitor was out of warranty so I just replaced it.

So in my experience I would say they could appear at any time.
