Dead pixel on laptops screen

Dead pixel on laptops screen

Hello Howel.

Dead pixels are transistors in the LCD panel that are permanently off.  If your panel is TN (the most common type) it will appear as a white dot on your display.  Dead pixels are usually due to a manufacturing defect.  If you find dead pixels on your monitor (especially when it is brand new), it is best to check out the warranty and returns policy of your manufacturer and have it replaced if it falls within their warranty conditions.  Some manufacturers specify the number of dead or defective pixels that can be considered "replaceable".  If the number of dead pixels is below the limit, then I'm afraid you are out of luck.

To answer your question, aside from protecting your laptop screen from hard bumps, rough handling and exposure to excess moisture (i.e., don't spill anything on it), there is not much you can do if the dead pixels are the cause of a manufacturing defect.  If the number of dead pixels increase, avail of your manufacturer's warranty.

Hope this helps!
