Perhaps a "bit" paranoid.
I'm running 3 monitors bought across at lest 7-8 years.
Got the first Dell 2405FPW brand new directly from Dell when they first came out for about $1200 as I recall. It has 3 dead pixels that it had the day I opened the box. Not nearly enough for Dell to replace it (ugh). They are really only visible with a full white screen though so it has never been a big deal and I LOVE the monitor otherwise.
Got the 2nd 2405FPW a few years ago used on E-Bay for around $300 and the 3rd one only a month or so back, again from E-bay for $120 when I decided to buy the W2 stand and go wide. They both are great. Have not found a dead pixel yet.
In part, maybe I just got lucky and I think in part they are a pretty decent quality monitor. They work together very nicely.
NOTE: The "reset to factory default", base color settings on the three don't match up (very noticeably different). I had to go in the screen menus and manually set the brightness, contrast and RGB values the same on each one and they all look identical by doing it that way. No idea why they have different 'default" color/brightness/contrast values set in their firmware.

On the other hand, I have 5 identical dell 20" monitors that I set 4 up in a quad stand at work. 1 of the quad just would NOT match colors/brightness with the other three no matter what I tried but luckily I had the 5th one available to swap that odd one out with and resolved the issue.
So it can go either way.
