Take a nice
look at your notebook computer screen. Do you find some tiny dark spots? You could have dead pixels. One of the most expensive parts of your notebook computer is the LCD screen.
LCDs are highly sensitive and any amount of pressure, touching or handling may damage it. As such, dead pixels arent an uncommon thing. Apparently, some degree of dead pixels is to be expected. Still if you have a lot of them, it would be classified as a defective screen. So, how do you determine if you have dead pixels?
Before we go there, contruct
sure its not just dust. Clean your screen first. The best way to do that is to use a soft cotton cloth - no rags or paper towel as they can scratch your screen easily. Moisten the cloth with plain old water and wipe the screen gently.
Side note: Ive also tried maintaining my screen dust free of cost with a Swiffer Duster. These are inexpensive, very soft and they pick up the dirt not just re-distribute it. It has worked well. Of course, this will not take care of smudges or dried on dirt. So you will
still have to utilize the cotton cloth and water combo sometimes.
Once youve cleaned it, you may run a quick check with a free of price
software called Dead Pixel Buddy. Its basically a very simple document
that will rotate your screen through all the basic colors. This way you can tell if a pixel on your screen is not displaying properly. One tip, you might want to get a help of a friend. Two sets of eyes are better than one especially since pixels tend to be miniscule.
You might
also do a low technology
way by changing your desktops background color to black, white, red, green blue and yellow, checking the screen each time you change the colors. This is of course not fool proof especially if you have tons of icons on your desktop but its a dazzling backup check if you dont have Internet access to download the document
or whatever the case might
be.
If you do find dead pixels, dont panic yet, as mentioned earlier, a small amount of dead pixels could be inevitable but if you have a lot of them and your notebook computer is still under warranty, this could be
a great instant to call up the manufacturer and ask for assistance.
