Handle scratches and dead spots on laptop screen

The first thing to do when buying a smartphone, laptop or LCD TV screen is to check the dead pixels.If you buy a branded product such as a Dell monitor, Asus laptop or Samsung smartphone, you will be guaranteed a one-time replacement within the warranty period.So you need to know how to check or handle dead pixels on the screen.The two most annoying problems with the most common screen when you use a laptop are scratches and dead spots.Here are some ways to handle them.

A scratch may be created by you, maybe they are available when you buy it. So, before choosing to buy, do not forget to turn off your computer screen and turn the screen in the light directions, you will easily detect these scratches, even if they have been 'processed'.

In the process of use, you must pay attention to sharp objects, most often office supplies and . nails, when bringing them near the screen. For safety, the best way is to use a screen protector. It's better that you have to replace another patch when they are scratched, rather than losing the value of the computer.

Worst of all, when your screen scratches, use vaseline grease (available at pharmacies). The procedure is to clean the screen with a suitable solution, then apply the Vaseline to the area with the scratch, and finally clean the excess fat, leaving only a sufficient amount of vaseline in the scratch.

Another reason is that for models, such as IBM, there is a mouse pointer between and above the keyboard, when you close the screen and seal the device too tightly in the bag, the mouse control button itself. This will scratch the screen. Using a keyboard cover pad before closing the lid will help you prevent this 'accident'.

On the dead spot on the screen, there are two forms: either they die (ie, dead pixels) - meaning you always have a black spot at that location, or they are stuck (stuck pixels) - that is, they only represent one color, not all color states.

You also need to detect these dead or dead spots before choosing to buy a laptop. A free, compact program that runs on floppy disks, CD or USB called Dead Pixel Locator (How to detect dead spots on the Desktop) will help you detect these dead spots by displaying the screen. with turn the standard colors. Each manufacturer has a limit on the number of dead spots that can be on the screen at the factory (usually four). If you exceed this limit, you can request another product.

Distinguish dead pixels (irreparable) and pixels (editable)

A pixel is a light colored dot that cannot be updated when neighboring pixels change. This pixel image is most prominent when the rest of the screen is black and it is different from the dead pixel. A pixel is a single color such as red, green or blue and the dead pixel is black. Although a pixel pixel can be processed, dead pixels are rarely editable. A pixel is nearly dead and only when the sensor gets hot, these points are called hot pixels.
