This cannot be said if the said item is of generic brand. Without further ado, here are 6 free tools to detect and fix dead or stuck pixels.

Stuck (Fixable) vs. Dead Pixels ( Not Fixable)

A stuck pixel is a bright dot of colour that fails to update when neighbouring pixels change. Stuck pixels are most noticeable when the rest of the screen is black. Stuck pixels are different from dead pixels. A stuck pixel is a single color – red, green, or blue – all of the time. A dead pixel is black instead. While it’s often possible to “unstick” a stuck pixel, it’s much less likely that a dead pixel will be fixed. While a dead pixel may simply be stuck at black, it’s possible that the pixel isn’t receiving power at all. A faulty pixel displaying the color white all of the time is known as a “hot pixel.”
