No that's a pretty standard well-standard, if you go to lenovo/dell/etc. they generally will say 1-3 dead pixels is within normal conditions.
These guys are selling this at a loss (or near loss), they're trying to be upfront to lower the number of returns - and more importantly chargebacks and disputes.
Huh. I've only had one stuck pixel in my life and I was able to fix it by poking it with a pencil eraser. Guess I've been lucky. 3 in one screen is a lot.
Depends on how many pixels there are in total. I have two blue pixels on my 4K 28" display… if I'm able to see them, that means I'm sitting too close :D
It depends on what's actually wrong, but in some cases, yes. Sometimes it's possible to unstick a pixel by just displaying the right sequence of colors; poking the screen is essentially a more brute-force variation of that.
