With the advancement of display technologies and improvements in manufacturing processes, the occurrence of dead pixels has reduced significantly. However, it’s still a possibility with any display device. Some display manufacturers provide warranties or guarantees against dead pixels for a specified period.

In addition to being a visual nuisance, dead pixels can also affect the overall performance of the display.
