What is a dead pixel?

I kept in mind one time when I had a client who purchased from me a new Neo laptop. We all knew that the laptop he bought from us was a brand new one and I can attest to that because it was fully sealed and covered. Since my client was so excited, he didn't open and check it for a test instead he toke it away from me like a snatched. As time goes by, he went back to me and decided to ask for replacement. I immediately called a technical support and the sales representative of the product and discussed about his complaint. Unfortunately, one to three dead pixels is not covered for their policy. So, the brand new laptop which he toke and ran it away from me can't be replaced anymore. Lesson learned, take it slowly but surely. Don't be a snatcher. hehehe
Remember that notebook manufacturer have their own policy on how many dead pixels warrants a return and replacement. Neo considers a screen defective only if it has three or more faulty pixels and even Mac PC will do the same policy. The problem is, most people are not aware of this policy before they get their notebook and falsely assume that one dead pixel is good enough to ask for a replacement, but this is generally not the case. Well, LCD screens are the most likely component to contain noticeable flaws in the form of the dead pixels. There are 3.9 million sub-pixels (red, green and blue) on a standard 1280x1024 resolution LCD monitor, and each of these is a transistor. Occasionally these individual transistors responsible for carrying current to a pixel will either short out or remain open resulting in what is called a dead pixel. Dead pixels are rare and largely go unnoticed by the user. By the way, If you are planning to buy anything for your special love ones, don't forget to visit my store. You can buy online.
