I bought a used monitor (Dell P2217H) and it came with this defect, I can´t return it becasue is used







I don´t know if are dead or just stuck pixels, i investigate and apparently, stuck pixels can be fixed via software
One is grey and other is half blue and half red

You can try and work with a white background and see if the pixels are black. Similarly, on a black background, if the pixels are white, then you've got yourself a monitor with dead pixels. I've read on other threads and seen in person that the monitor you currently have suffers from dead pixels.

But if the pixel is gray, ¿Is dead or stuck?
I know pixels in green, red or blue are stuck, and black ones are dead, but what´s the case if is gray or half one color, half another?
