Dead Pixels

[B.W.]

What are dead pixels on a TFT display, what do they look like. With a new
laptop do you expect to have some?

B.W.

Permanently black or permanently white.
If you have either, sometimes a small tap on the back of the screen fixes
it.

The industry standard allows a limited number of bad pixels on a new screen.
Some factors are location, total quantity, quantity adjacent etc.
Check your manual and/or contact the manufacturer for details.
If you call, do not be satisfied with what you may be told, ask for a web
reference.

Another popular method is massaging the dead pixel with a finger. This
involves covering the finger with cloth (such as a soft glove or soft cotton
rag), gently pressing on the LCD display directly over the dead pixel, and
rocking the finger in an up/down or side to side motion. I first read about
this method several years ago and have used it twice to successfully fix
dead pixels.

Just don't poke your finger through the screen.

Permanently black or permanently white.

The bit may be permanently black or white, but the colour (made from
multiple bits) may not be. I have a dead pixel that is permanently red.

There was an article about this on news.com a while back. Various
vendors have different policies, but they typically replaced the LCD
monitor only if there were more than 6-10 dead pixels.

LOL! You did notice I carefully added the word "gently" to those
instructions - a disclaimer to prevent someone coming back to scream at me
after pressing too hard. A person will have to press in on the screen, but I
do hope they use a little common sense when doing so.
