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's not that dead pixels are common, instead that it's hard to guarantee none will occur at n% across a population of screens.
wait, you can just poke them away?
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.
And I’d bet that won’t work anymore with screens that are behind a sheet of glass
